Abstract
Purpose
Using the theory, construct, method, moderator (TCMM) format, this framework-based review critically analyses the mobile financial services (MFSs) field through a detailed synthesis and analysis of a sample of mainstream empirical research published in various scientific journals within the period 2009–2020.
Design/methodology/approach
The authors followed a three-step structured approach suggested by Webster and Watson (2002) to search for the literature to synthesise the global perspectives on MFSs and their associated applications and systems. The literature research resulted in the identification of 115 most relevant articles.
Findings
The authors identified three major categories or domains within the MFSs comprising the entire spectrum of digital financial services. To facilitate the literature analysis, TCMM is developed and proposed as an organising framework. Moreover, the authors also developed and presented the comprehensive framework of MFS domains and explicitly identified 14 different research themes for future research in MFSs.
Originality/value
Prior attempts to synthesise and analyse mainstream academic research in MFSs have been scant and limited to a specific MFS domain: mobile banking or mobile payment. The authors synthesised a more extensive body of knowledge and provided a global perspective on the MFS field. Unlike the past literature reviews which followed traditional frameworks such as antecedents, decisions and outcome (ADO); TCCM; and 6 W Framework (who, when, where, how, what and why), the authors developed and proposed TCMM as organising framework.

1. Introduction
An exciting transition has been taking place within the banking and payment fields in the last four decades. Branch banking has been taken over by branchless banking with anytime – anywhere services. Net (short for Internet) banking has been transformed mainly into mobile banking. The automated teller machines (ATMs), point-of-sale (POS) terminals and payment cards have been replaced with near-field communication (NFC)-enabled and contactless mobile payment applications, including mobile wallets and wearables. The chat-bots and robo-advisors have created an intelligent mobile banking and payment culture in many developed countries. Nonetheless, the consumers of branchless banking in Western countries have shown greater reliance on Internet- and mobile-based access to their banking accounts and to other value-added services, such as investments, advisory services, loans and mortgages. Consumers in non-Western or developing countries, on the other hand, have started adopting and using the mobile phone to execute traditional retail transactions such as fund transfers and paying utility bills. Mobile money has in fact played a significant role in transforming the socioeconomic conditions of many underprivileged and unbanked population segments in non-Western countries (Glavee-Geo et al., 2019; Karjaluoto et al., 2021).
Given the increasing use of and demand for smartphones and mobile banking and payment services, research examining the consumer, management, policy and theoretical perspectives in the mobile financial service (MFS) area is underway (Chawla and Joshi, 2017). However, efforts have been made to synthesise a more extensive body of knowledge in the MFS field, albeit with a limited scope and purpose. For example, Shaikh and Karjaluoto (2015) conducted a domain-specific structured review in the mobile banking adoption field from 2005 to 2014. In the context of the Gulf Cooperative Council countries and based on 46 articles, Alkhowaiter (2020) produced a comprehensive literature review and performed a meta-analysis of the factors affecting the use and adoption of digital banking and payment methods. Dahlberg et al. (2008) published a framework-based review in the mobile payment services field based on 73 articles published within the period from 1999 to 2006. Kim et al. (2018) conducted a systematic literature review based on 54 academic research papers in the areas of MFS, financial inclusion and developments. Unlike the previous research efforts, where the synthesis of the literature was limited to a specific MFS domain (mobile payments, mobile banking) or region (Gulf Cooperative Council countries), the purpose of our research endeavour was to conduct a framework-based review of the literature on the global MFSs.
In addition, Paul and Benito (2018) used the antecedents, decisions and outcome (ADO) format in their review article; Paul and Rosado-Serrano (2019) developed and used the theory, construct, characteristics and methodology (TCCM) model and Xie et al. (2017) used the 6 W Framework (who, when, where, how, what and why). We, on the other hand, used the Theory, Construct, Method, Moderator (TCMM) model after considering the nature of the MFS field and the articles selected and included in this framework-based review (quantitative/survey and mix-method approach). Survey articles provide objective information concerning the theory, constructs, method and moderators used in such articles (Shaikh and Karjaluoto, 2015). Nonetheless, the purpose of introducing the TCMM model was to offer a new or better model while relying on the existing models, such as TCCM. Our suggested TCMM is somehow a close variant of TCCM model developed by Paul and Rosado-Serrano (2019). Another purpose of developing the TCMM framework is to evaluate the extent to which previous research within the MFS field had used moderators in their studies. Similarly, the TCMM framework considered the use of “moderators” as a special type of constructs that can help researchers to develop novel and interesting relationships between constructs in MFS research.
The synthesis of these moderating variables as envisaged in the TCMM model could identify the gaps such as which variable (including the control variables) has been used extensively and rarely. In addition, moderators provide new insights and contingency relationships amongst constructs without which new perspectives of a phenomenon could be hidden. Moderator effects occur in situations where the moderator (an independent variable or construct) changes the strength or even the direction of a relationship between two constructs in the model (Hair et al., 2017, p. 41). This framework-based review was meant to contribute to the understanding and distinction of various domains identified as falling within the wide ambit of MFSs. We offered new definitions of mobile banking, mobile payments and mobile money and proposed the TCMM model. We also developed and proposed a framework presenting the MFS ecosystem and explicitly identified the future research areas left unidentified by the research on MFSs to date.
While drafting the plan for the future research directions, we considered emerging themes such as pandemic (e.g. the COVID-19 pandemic), new regulatory frameworks (General Data Protection Regulations, Revised Payment Services Directive [PSD2]), technologies (wearables), methods (experimental), intelligent mobile banking and payment systems using chat-bots and the emergence of new demographic groups. The primary literature search resulted in 115 relevant articles published within the period from 2009 to 2020. The reason for the selection of a 12-year period for the review, from the beginning of 2009 to the end of 2020, is that MFSs received a significant boost only after the advent of the smartphone, which was introduced by Apple Corporation in 2007.
The major contribution of this literature review is the identification of three major MFS domains, which are defined as a wide range of traditional and value-added services, retail transactions, banking activities and information accessible through portable devices and wearables (Dorfleitner et al., 2019). These three domains comprising the entire spectrum of digital financial services are as follows: mobile banking services (including downloadable mobile applications), mobile payment services (including both proximate and contactless/remote mobile wallets and smart watches) and mobile money services (including branchless, short-message service [SMS], agency and money transfers). Moreover, we highlight herein several implications beneficial for banking and payment industry professionals (e.g. bank managers, digital marketing managers), regulators and policymakers. For example, the use of the TCMM model has identified several critical variables and consequences that affect consumer choices, behaviours, and attitudes towards the adoption of various MFS applications and systems. Therefore, bank marketing managers are better informed about the key factors that influence MFS adoption. This can help in the formulation and implementation of effective marketing strategies. In addition, MFSs have grown into a new subsector of the economy, supporting the financial inclusion programs started by government agencies in various countries. Our review has provided further insight into the different MFS domains, which would, for example, help regulatory authorities promote a cashless culture, document transactions, promote transparency, reduce the volume of the informal economy and reach out to the unbanked consumer segment.
For the organisation of the rest of this article, we present the research method that we used in our review in section 2 and define the frameworks and models widely accepted amongst the researchers within the MFS field and the choices of outcome constructs, moderators and determinants of adoption and use of MFSs in section 3. We then present a comprehensive framework of the MFS ecosystem in section 4, discuss the findings of the review and highlight their implications in section 5. We allude to the study's limitations and explicitly identify the future research areas in section 6.
2. Research method
To help identify the articles to include in our literature review, we relied on interdisciplinary journals and the journals in the business, marketing, retail, consumer behaviour and information system fields. Further, we employed the structured approach suggested by Webster and Watson (2002) to search for the most relevant literature within the MFS field, as presented and discussed below.
All the authors were made responsible for searching and including in the article the empirical studies that analysed the user behaviour, intention and beliefs in the pre-adoption, continuous use, sustained use or post-adoption of MFSs in different regions and markets, including developed, emerging and developing ones. This was done by scanning the abstract, introduction and method sections of the articles that were found. Articles on the most recognised multidisciplinary databases for peer-reviewed contents (Elsevier/ScienceDirect, ProQuest, Web of Science, EBSCOhost and Emerald) were accessed using different but relevant keywords, such as mobile financial services, mobile banking, mobile payments, mobile wallets, mobile money, agent banking, SMS banking, portable banking, branchless banking, banking for the poor, micro-banking and intelligent mobile banking.
We limited our literature search to the period 2009–2020. In total, the 115 most relevant journal articles (excluding conference proceedings and book chapters) were shortlisted and included in the review. The 115 articles thus provide a holistic overview of the MFS field and are considered valuable. The lead author summarised the articles in an MS Excel sheet with multiple columns for easy synthesis and retrieval of information. Some of these columns created in the Excel sheet featured the year of publication, context (location or research site), moderators analysed, theory/model/framework, construct/factors/antecedents and research methods that were used. The Excel sheet was subsequently examined by each of the remaining authors to ensure that the obtained articles were placed under the right categories. Finally, all the authors examined each article together to build a consensus before further analysis. Our analysis of the 115 articles included in our review revealed that the volume of published articles in the MFS field has increased since 2017. To be specific, we divided the 2009–2020 time period into three periods, each consisting of four years: 2009–2012, 2013–2016 and 2017–2020. In the first period, 31 peer-reviewed journal articles were published; in the second, 38, and in the third, 46.
During the data analysis process, each author performed a detailed analysis and interpretation of one domain from the proposed TCMM framework, and then wrote about the results of the analysis and interpretation in the findings section. The results of each author's analysis and interpretation were subsequently examined by all the authors for validation, synergy and consistency.
3. Findings
3.1 Mobile financial services
The term MFSs is used to represent an all-inclusive service portfolio for consumer segments accessing and using retail- and business-related banking and payment services on mobile devices. Considering the usefulness, ubiquity, convenience, outreach and low-cost benefits of MFSs, some authors (e.g. Dorfleitner et al., 2019) have used the term MFSs to refer to microfinance or transformational banking; the term has also been used for the consumers living in remote areas and popularly recognised as unbanked or underbanked.
Before the advent of smartphones in 2007, low-cost and feature phones were primarily used to communicate through voice calls or SMS messages. The emergence of smartphones with Internet connectivity marked the turning point in the banking and payment industry, expanded cell phone use for value-added services, revolutionised the financial industry and paved the way for the creation of various smart and disruptive business models. Consequently, in less than a decade since smart devices first made their way into consumers' everyday lives, mobile commerce and mobile payments have become mainstream, outpacing the traditional banking and payment models, including branch, ATM, net, POS and SMS banking, referred to collectively by Shaikh and Karjaluoto (2015) as an alternative or alternate delivery channels.
The three domains identified in the MFS field (i.e. mobile banking, mobile payments and mobile money), although sometimes cross paths and overlap their scope and usage with regard to the nature of the transactions (micro and macro), consumer–bank relationship (with and without a formal bank account), consumer segmentation or types (banked, under-banked and un-banked), access methods (remote and proximity) and mobile devices (smart and traditional or feature devices) used to access such services, they differentiate from each other (See Table 1). For example, mobile devices used for conducting mobile banking include cell phones and tablets. Therefore, accessing banking services from a laptop or a personal computer is not considered mobile banking, rather, laptops are largely aligned with the online/Internet banking category (Shaikh and Karjaluoto, 2015). Also, unlike mobile banking, a formal relationship between a person and a bank is not required in mobile payments. Third-party applications developed and provided by, for example, FinTech and telecom companies can be used to receive and send funds using mobile payment applications. Mobile money, on the other hand, is considered appropriate for that consumer segment which is popularly known as under-banked or un-banked (Glavee-Geo et al., 2019).
3.1.1 Mobile banking
In one of their highly cited articles, Shaikh and Karjaluoto (2015) offered a comprehensive definition of mobile banking: an innovative service for conducting financial and non-financial transactions using a mobile device, namely a mobile phone, smartphone or tablet. Earlier, the segregation between the financial and non-financial services in mobile banking was not evident, which enlarged the scope and purpose of mobile banking. Nonetheless, a summary of the mobile banking definitions appearing in the historical and contemporary literature is given in Table 2.
As evident from Table 2, the research has considered mobile banking an innovative channel; an application of the mobile commerce; a sub-set of electronic commerce; a cost-effective service available anytime, anywhere; and a natural evolution of electronic banking. These definitions of mobile banking when synthesised provided a new perspective on mobile banking technology, systems and services. This study, therefore, proposes the following definition of mobile banking:
Mobile banking, also referred to as cell phone banking, is an innovative and cost-effective application of mobile commerce with extended capabilities, which is used virtually by bank account holders using web browser or downloadable mobile application on smart phones or tablet with internet connectivity to access the traditional and value-added financial and non-financial services including funds transfer, investment advices, utility bills payment, balance enquiry, security alerts or notifications, new product or service promotion, conveniently anytime anywhere.
3.1.2 Mobile payment
Unlike mobile banking, the mobile payment technology and services were introduced to broaden the scope of payment services, including the value-added services using different payment technologies, such as radio frequency, NFC and the quick response code. The key to mobile payment, including the mobile wallet, is the downloadable application. According to Karjaluoto et al. (2019), the downloadable mobile applications for mobile payment contain several features and payment options, provide broader and more cost-effective service options and better protection, and primarily target banked and de-banked consumers. De-banked consumers refer to those who refuse to access and use various alternative delivery channels despite the availability of these to them and who refuse to maintain any formal relationship with any bank in the form not only of a checking account but also of a savings account (Shaikh and Karjaluoto, 2016). Most of these de-banked consumers are Millennials, Generation Z and Generation Alpha and rely on value-added mobile-only financial and payment services (Shaikh and Karjaluoto, 2019).
Prior research (Liébana-Cabanillas and Lara-Rubio, 2017; Ghezzi et al., 2010) has considered mobile payment applications star or killer applications in the mobile communication field; a business activity; a mobile wallet; and a contactless payment system. A summary of the definitions of mobile payment proposed in the historical and contemporary literature is given in Table 3. After synthesising these definitions, this study proposes the following definition of mobile payments:
Mobile payments, also referred to as mobile wallet, is anytime anywhere payment mechanism offered by banking and non-banking entities including FinTech, which can be executed seamlessly in a proximity and remote mode by anyone with a handheld device and peer-to-peer or mobile payment application to access the value-added services and conduct micro and macro payments electronically including funds transfer, utility bills payment, making donations, mobile balance pop-up etc.
3.1.3 Mobile money
Various terms have been used to represent mobile money services, such as branchless banking, banking for the poor, mobile transfers, SMS banking and agent banking. According to the World Bank Global Findex Database (2018), over 1.7 billion adults globally are unbanked. Yet, many of these unbanked people own a cell phone that can help them access formal payment and other financial services (Glavee-Geo et al., 2019).
Mobile money, defined as a financial innovation that provides transfers, payments and other financial services at a low or zero cost to individuals in developing countries where banking and capital markets are deficient and financial inclusion is low (Pelletier et al., 2020), has an enormous potential to reach the unbanked. It has been widely considered a crucial technology for escaping poverty and disparities. To obtain this revolutionary service's benefits, all that one needs is a feature phone with the standard network coverage. Unlike tellers, who provide customer service in bank branches, or ATMs, mobile money depends on an agent network and is based on a straightforward business logic: high volume, low value. This logic entails that mobile money promotes high transaction volume with low monetary value. This makes mobile money very different from mobile banking and mobile payment, both of which facilitate high-value, low-volume transactions. The explanation by Suárez (2016) and Heyer and Mas (2011) of the crux of mobile money and how it differs from the mobile banking and mobile payment technologies provide much relief. For example, mobile money can be implemented in emerging and developing countries where there are no financial alternatives or delivery channels available. The presence of any alternative delivery channel will dilute the mobile money initiative. Also, there must be a high mobile phone diffusion rate amongst a wider segment of the population destined to adopt and use mobile money. There must also be a sufficient demand for formal or documented financial services. A favourable regulatory environment supporting the market's supply side and technological innovation is required.
A summary of the mobile money definitions proposed in the historical and contemporary literature is given in Table 4. The synthesis of these definitions allows us to suggest the following more comprehensive definition of mobile money.
Mobile money, also referred to as branchless or agent banking, is a financial inclusion tool used in many developing and emerging countries by financially excluded rural or less privileged communities with no or limited access to formal banking services such as branches, ATMs, POS and Internet banking, to send and receive the funds and making micro payments across vast distances without being limited to location and time, using a feature phone with no internet connectivity using a simple short-message service (SMS) technology anytime anywhere.
3.2 Theory, construct, method, moderator framework (TCMM)
3.2.1 Theoretical underpinnings (T)
Figure 1 provides a snapshot of the theories, models and frameworks used in the MFS field obtained from the literature included in our review. Nonetheless, from the perspective of method (see Figure 2), the articles' synthesis revealed that most of the studies included in the review had used technology of acceptance model (TAM) and its modifications (35 and 30%) and unified theory of acceptance and use of technology (UTAUT) and its modifications (24 and 21%). Instead of relying on a specific model or framework, the authors of 17 studies (15%) made their theoretical models consist of various factors and relationships, and made explicit assumptions and caveats underpin them. These new hypothesised relationships between and amongst various factors have provided several theoretical contributions.
3.2.2 Constructs or variables (C)
Several constructs or variables (dependent and outcome) were used to examine consumer attitude towards adopting and using MFSs and similar technologies and their behaviour and intention regarding these. Understanding how these constructs and outcome variables affect the consumer decision-making process has always been a point of interest in academia and the industry. The synthesis of the 115 empirical studies in our review provided valuable information regarding this matter, and the use frequency of constructs such as perceived ease of use and perceived usefulness, effort expectancy and performance expectancy was quite obvious, especially after considering the frequent use of TAM and UTAUT and their modifications. Table 5 provides the frequency of use of the constructs in the MFS domain in our sample of studies published within the period from 2009 to 2020 (frequency >10). More specifically:
Perceived ease of use and its conceptually identical constructs (effort expectancy, self-efficacy and complexity) were found in 93 (81%) of the studies;
Consumer behavioural intention and closely related terms such as usage intention, intention to use and usage behaviour were found in 87 (76%) of the studies;
Perceived usefulness and its conceptually analogous constructs (performance expectancy, perceived performance and relative advantage) were found in 82 (71%) of the studies; and
Trust (including perceived trust) was found in 68 (59%) of the studies.
The psychological science variables such as social influence, which is considered akin or similar to the variable subjective/social norms, also received much attention from previous research. In total, 57 studies (50%) examined the effects of social influence, including subjective/social norms, on various antecedents/variables in the context of MFS adoption and use. For example, previous studies (Baptista and Oliveira, 2017; Oliveira et al., 2014) found that social influence positively affects consumer use intention and adoption of MFSs. The variable social influence reflects the notion that user behaviour is influenced by the way the peers, friends or family members value IT and the related services (Baptista and Oliveira, 2017), such as MFSs and their associated applications.
Considering the nature of online and mobile transactions, which are considered highly risky and prone to fraud and misuse, the variables perceived trust and perceived risk, both product-related factors, are also considered significant in the prior research, primarily affecting the adoption and use intention and the attitudes and behaviour of consumers. Consumer trust (initial, cognitive and emotional) was used as an independent and outcome construct in 68 studies (59%) while perceived risk was used 43 times (37%). Most of these studies examined the negative effect of perceived risk on various variables, such as attitude towards MFS adoption and use and behavioural intention to adopt and use MFSs (Glavee-Geo et al., 2017; Makanyeza and Makanyeza, 2017), relationship quality (Chen, 2012) and performance expectancy (Luo et al., 2010).
3.2.3 Methods and markets (M)
Most of the studies that were included in our review used the quantitative or survey method (103 studies or 90%), and a few used mixed methods (12 studies or 10%). Most of the studies were conducted in emerging markets such as China (16 studies or 14%) and India (11 studies or 10%), followed by Taiwan (8 studies or 7%), South Korea (7 studies or 6%) and Ghana (6 studies or 5%). Five studies (or 4%) were conducted in Iran, Malaysia and the USA. Of the 115 studies included in our review, only three (or 3%) conducted a multi-country assessment (See Figure 3).
3.2.4 Moderators (M)
In addition to the main constructs (independent or dependent variables), several moderators (also known as contingent variables) were used in the reviewed research articles to examine how a moderator could affect the strength of the relationship between an independent variable and a dependent variable. Research has divided these moderators into three major categories: (1) the demographic moderators gender, age, profession and income (Chaouali and Souiden, 2019; Glavee-Geo et al., 2017; Baptista and Oliveira, 2017); (2) the cultural moderators individualism/collectivism, uncertainty avoidance, masculinity/femininity and power distance (Baptista and Oliveira, 2015) and (3) the psychological moderators self-efficacy, perceived image, subjective norms, personal innovativeness (Mohammadi, 2015), trust and perceived risk (Chung and Kwon, 2009) (see Table 6).
For example, examining UTAUT2 with cultural moderators, Baptista and Oliveira (2015) provided new insights into the variables affecting the acceptance of mobile banking and how culture influences individual user behaviour regarding it. The study finding suggests that collectivism, uncertainty avoidance, short term and power distance are the most significant cultural moderators.
4. Comprehensive framework of MFS domains
The comprehensive framework of the MFS domains that we used in our review is shown in Figure 4. This proposed framework has identified the service dynamics and has segregated the services offered by mobile banking into two domains: financial and non-financial. This segregation was identified earlier by Shaikh and Karjaluoto (2015) in their highly cited article entitled “Mobile banking adoption – a literature review”. The financial services accessed and executed by the consumers include fund transfer, cash withdrawal and utility bill payment. Non-financial services include balance inquiry, receiving essential notifications, chat-bots and a conversation with robo-advisor. Chawla and Joshi (2017) classified MFSs and the associated offerings into three broad categories: banking services, payment services and value-added services. Banking services largely represent innovative and downloadable mobile apps and website and text banking. Payment services include peer-to-peer payment, utility bill payment and POS banking using NFC payment mechanisms. Value-added services include virtual wallets, advisory including virtual support, personal financial management, cloud storage and wearables.
The term customer dynamics refers to the classification of the consumers into different domains considering their choices, behaviours, habits, use purpose and level of access to the banking and payment technologies and alternative delivery channels. Banked consumers can access and use the products, services and channels anytime, anywhere. Un-banked consumers, on the other hand, have limited or no access to banking and payment services. Here, mobile money technology and services provided relief to many.
The demographic or regional dynamics or classification and user dynamics mainly imply the applicability and feasibility of offering various MFSs to the demographically dispersed population. More specially, reaching a demographically dispersed potential consumer base and providing them with formal banking services have always been challenging. This is true of many unbanked segments in Africa (Baptista and Oliveira, 2015). A novel retail mobile banking service initiative called branchless banking was introduced in the 1990s to several developing countries, such as Kenya and Ghana, and several emerging countries, such as Brazil and South Africa. For instance, the branchless banking scheme called M-Pesa introduced in Kenya in early 2007 was phenomenally successful (Dermish et al., 2011). It is now being considered a catalyst for much of the research done on branchless banking to date.
The institutional dynamics segregate all institutions that develop and deploy mobile-based financial and payment services, such as government and regulatory bodies, banking and microfinance entities and non-banking entities such as merchants, FinTech and third-party developers. In addition to the banking entities traditionally considered solely responsible for developing and deploying various banking and financial services and alternative delivery channels, the participation of non-banking entities in the MFS ecosystem is growing primarily due to the global recession in 2008 and the promulgation of PSD2 and open-banking regulation in 2018. This changing regulatory landscape has structurally disrupted the traditional banking ecosystem, transformed the retail banking and payment landscape, and has widened the scope and increased the use of MFSs.
Published in May 2018, PSD2 of the European Commission (EC) requires banking companies and credit unions to provide third-party app developers and service providers such as FinTech with access to their consumer data. This conspicuous development has transformed the banking and payment landscape, and thus also the bank–customer relationship. Moreover, these revolutionary guidelines will empower non-banking entities such as PayPal and technology titans such as Facebook to develop and deploy a wide range of banking, financial and payment products according to the needs and requirements of the consumers, thereby creating several challenges and competition for the diligently regulatory banks.
Concerning the COVID-19 pandemic and social distancing, as of this article's writing, the pandemic was still raging, and people worldwide were getting used to the new normal. The pandemic has created wide-ranging challenges and has worsened the situation for many traditional banking and payment players as it increased the demand for more digital, contactless, remote, safe and clean services. Consequently, the digital and remote retail payment services increased across the globe; consumers began availing of these services more frequently, and the use of publicly shared devices like ATMs and POS terminals was reduced exponentially. COVID-19 has boosted the demand for more remote services, including the demand for mobile-based financial and payment services.
5. Discussion
The consumer behaviour and fast-emerging mobile and contactless technologies have widened the differences amongst the three domains and have therefore enriched the financial landscape. For instance, the institutions have been segregated to provide financial services to consumers. Here, unlike the banking sector, which was traditionally responsible for developing and deploying banking services, including mobile banking, the FinTech companies such as PayPal and the technology titans (Google, Facebook) are offering digital payment options and undertaking several initiatives to provide a host of services to the consumers on their cell phones and tablets. Unlike mobile money services, mobile banking and mobile payment services are diligently regulated and largely developed and deployed by banking companies and credit unions.
The new regulatory landscape has created a new breed of financial institutions such as FinTech offering mobile banking and payment services. In addition, the primary devices used for accessing and conducting mobile banking are mobile phones and tablets whereas laptops and personal computers are used to access and conduct Internet banking transactions. Further, the analysis of the literature suggests that the research on the actual continuous use of MFSs is particularly relevant and essential for the financial services sector, including banking companies, mainly for two major reasons. Firstly, the relationship between a customer and an organisation changes over time. Customer relationships' dynamic nature is especially important in service industries that offer continuous services, such as financial and insurance services (Shaikh et al., 2015). Secondly, a huge investment underpins mobile telephone and technology development and implementation and the underlying purpose of this investment is to create a sustainable and long-term relationship with the consumers, which is possible only when the consumer accepts and continuously uses the company's technology, service or product.
Our research revealed a trend in the evolution, development and growth of the MFS field. A shift in mobile banking and payment research was also observed. For example, in the 1990s, non-empirical studies (essentially focussing on conceptual work) and practitioner-oriented work in MFS dominated the literature. In the early 2000s, empirical research (e.g. survey studies, case studies, field studies) started dominating the literature, showing the maturity of the field.
The context and the technical aspects of the studies published in the MFS field also vary. For example, in the 1990s, SMS banking started to dominate MFSs. In 2007, after the advent of smartphones and other smart devices, the changing regulatory scenarios in many countries provided greater depth and support to the banking and non-banking industries. Consequently, downloadable mobile banking and payment applications were developed, providing access to traditional and value-added services. These developments widened the scope and increased the use of mobile banking and payment applications and services. Academic research on such applications and services started appearing in mainstream journals in the early 2000s, and such research has been sustained to this day.
Similarly, PDA use in conducting mobile banking transactions faded away after the introduction of smartphones in 2007. The services offered through mobile banking services vary considerably in scope and nature. For example, mobile banking includes non-financial mobile accounting (e.g. mini-bank statement, balance enquiry, chequebook request, service notifications and saving beneficiary details) and other value-added services, such as mobile brokerage (selling and buying financial instruments) and MFSs (utility bill payment, fund transfer, making donations and insurance policy subscription).
Like ATM and Internet banking, branchless banking has been considered a separate alternative delivery channel in various countries, such as Kenya, Ghana, Brazil, India and Pakistan. To deal with the regulatory aspects governing digital banking, several developing and emerging countries have drafted a separate set of regulations on branchless banking. Other striking advantages associated with branchless banking are (1) unlike mobile banking, branchless banking does not usually involve cutting-edge technology and sophisticated services and (2) the branchless banking channel is used mainly for payments and transfers, not for savings or credit, but these additional services may be offered in the future.
For the banking industry, COVID-19 has accelerated the transformation of banking from paper-based to digital/online, with the consumers' banking preferences and financial sentiments rapidly evolving. It has also fast-tracked the digitisation program across the banking and payment industry. Notwithstanding, not many articles have examined the role played by the COVID-19 pandemic in promoting the digital culture. However, it has been widely accepted (Haapio et al., 2021; McKinsey and Company, 2020; Goodell, 2020) that the new normal has brought about noticeable changes in consumer engagement behaviour when accessing and using digital payment services, including MFSs. The same is also evident from the volume of publications of articles in the MFS field. Out of 115 articles published during 2009–2020 and included in this review, a noticeable increase in the publication of the articles in the MFS was noticed during the last four years, i.e. since 2017. This trend continues and further accelerated since 2019. This is perhaps due to the COVID-19 related crises and the consumer choices for more remote services using mobile applications.
5.1 Implications for theory and industry
Our systematic review has offered important theoretical contributions. Its initial contribution is the conceptualisation, validation and segregation of three major domains: mobile banking, mobile payment and mobile money. As explained earlier, each of these domains follows a different path and targets a different consumer segment. Consequently, this noteworthy finding provides the research in the field with an opportunity to highlight the importance of each of these domains for improving customers' attitudes, behaviour and intention regarding the adoption and use of MFSs and how each of these domains meet the consumer variant needs for more innovative and portable banking and payment services.
From a careful reading of the literature, it was observed that research has identified four distinct research streams: (1) consumer pre-adoption resistance behaviour towards business information systems (Laukkanen et al., 2009), (2) consumer pre-adoption acceptable behaviour towards business information systems (Hanafizadeh et al., 2014), (3) consumer post-adoption or continuous use behaviour towards business information systems (Bhattacherjee, 2001; Shaikh and Karjaluoto, 2015, 2016) and (4) consumer pre- and post-adoption behaviours towards business information systems (Kim and Son, 2009). Two major research domains, pre-adoption or acceptance and post-adoption or continuous use, were considered paramount when investigating MFSs globally. We also found that the individual acceptance of information systems remained a central and recurrent theme in consumer behaviour and business information system research in the MFS field (Bhattacherjee and Sanford, 2006), but little empirical evidence of the continuous or sustained use of MFSs is available. This is of much concern as the long-term development of MFSs relies on users continued use of them (Yuan et al., 2016).
Our TCMM framework-based review expanded the previous research by identifying and reporting the similarities amongst various variables, which provides vital information to the research when (1) constructing or modifying models or frameworks with added variables, (2) avoiding the overlapping of the variables and (3) seeking to improve the effectiveness and usability of the theoretical models. For example, our findings indicate that the variable perceived usefulness is akin to the variables performance expectancy, perceived benefit, relative advantage and perceived performance; perceived ease of use is similar to its antecedents effort expectancy, perceived self-efficacy and complexity; social influence is similar to subjective/social norm; facilitation conditions is similar to perceived behavioural control; perceived financial cost is akin to its antecedent perceived financial resources and perceived credibility is similar to its antecedents perceived security and privacy and structural assurance.
Another significant contribution of the TCMM framework-based review is the development of the “Comprehensive framework of MFS domains” as shown in Figure 4. We applied the TCMM framework to analyse MFS research and outline roadmaps for the future research in the three major research domains. Summarising the prioritisation of the variables affecting the consumer adoption and use of MFSs provide useful information for the research. For example, the results of our review suggest that the variables perceived ease of use (including effort expectancy, perceived self-efficacy and complexity), perceived usefulness (including performance expectancy, perceived benefit, relative advantage and perceived performance), trust, social influence (including subjective and social norms) and risk are the significant drivers of the behavioural intentions to adopt, resist and continuously use MFSs.
Our review suggests that consumers' decision to adopt and continuously use various innovative banking and payment services is primarily dominated by two major factors: the ease of use and usefulness of the services, which implies that the companies should simplify their offers and increase their customer utility. This will help the executives and marketing professionals effectively engage their customers across all touchpoints or alternative delivery channels to build customer commitment and achieve customer retention (Lemke et al., 2011). SMS-based mobile banking and payment services provide limited options and are considered less hedonic. Downloadable banking and payment applications provide high security and a wide range of services to consumers. Adding more hedonic features to SMS-based banking and payment, such as those that produce pleasure and provide leisure will increase the consumers' adoption and sustained use of such services, especially in emerging and developing countries.
The perceived value of MFSs has been sparsely used as an exogenous and endogenous variable in the extended research. In the simplest terms, price is what you pay for a service or product while value is what you get for what you pay. Particularly at the present time, when the benefits and advantages of MFSs are being considered, we believe that the industry players must have a clear understanding of what value creation means and must develop a value-minded approach. Unlike mobile banking and payment services, USSD- and SMS-based branchless banking services' uptake looks considerably high, especially in developing and emerging countries. Banking companies and other financial institutions should continue investing in the mobile money or branchless banking business and developing models of such to provide sustainable financial services, obtain an additional revenue source and increase their consumer base. After all, for most of the ‘bottom-of-the-pyramid underbanked and unbanked population’, it is either mobile or nothing (Dogbevi, 2010; Glavee-Geo et al., 2019).
6. Limitations and future research agenda
Our review was not without any limitations. One of its major limitations is the type of studies considered and included in the review. Although MFSs have received greater attention from academicians and practitioners of late, the practitioner-oriented articles published in renowned and predominantly practitioner-oriented journals were not considered and included in our review. In addition, our review was dominated by survey studies; non-survey studies were excluded from the review. Other study limitations and a comprehensive list of the future research directions are discussed below.
6.1 Mobile money, financial inclusion and the bottom-of-the-pyramid consumers
As evident from the TCMM framework and the resulting “Comprehensive framework of MFS domains” shown in Figure 4, few empirical studies on branchless banking (mobile money) were found, which were searched to contribute to the understanding of the bottom-of-the-pyramid consumers' adoption and use behaviour. In other words, the low levels of financial inclusion of a large number of mobile phone subscribers in emerging and developing countries make it imperative to investigate if an expansion of mobile phone deployment can generally contribute to social welfare, consumer well-being, greater financial inclusion (Ghosh, 2016) and the greater use of MFSs.
6.2 New methodical domains, including experiments and simulations
While a strong quantitative tendency characterised the articles that were included in our review, a few empirical studies grounded in a mix-method approach, including qualitative and quantitative methods, were found (cf. Lashitew et al., 2019). Quantitative modelling and measurement were used to explain MFS adoption and continuous use in specific contexts. Our review also showed the lack of certain methodological domains, such as experiments and simulations. Most of the cause–effect relationships implicitly argued for in the MFS literature were based on correlational studies. Future research may consider using other research methods, such as experimental research and simulation, in examining the various domains of MFSs. Methodological innovations in MFS research will provide robustness of the findings, a strong validation of theories and potentially new theory development.
6.3 Visualisation approaches and the mobile financial services field
Future studies should also consider using bibliometric networks to visualise publications within the three main fields (mobile banking, mobile payments and mobile money) with regard to citation, co-citation, bibliographic coupling and keyword co-occurrence. The visualisation approaches, such as the distance-, graph- and timeline-based approaches (Van Eck and Waltman, 2014), can help provide insightful findings in the area of MFSs.
6.4 Requirement of more comparative or multi-country assessments
Comparative studies of different countries can also help explore the differences amongst countries in consumer perceptions of the perceived value of MFSs due to the differences in culture, preferences, demographics and institutional contexts amongst countries. Although PSD2 was primarily meant for the European Union (EU) member countries, some non-EU member countries have also adopted it. Therefore, studies on the impact of PSD2 on the MFS users/consumers, banks and non-financial actors in non-EU member countries may be insightful. The possibility of PSD2 creating innovation opportunities and challenges outside the EU or the European Economic Community (EEC) cannot be underemphasised. Future studies investigating the impact of MFSs on consumers within and outside the EU/EEC will be useful to policymakers and managers for policy reforms and service design decisions regarding MFSs in such regions.
6.5 New regulations: the key driving force for mobile financial services
The EC developed and implemented PSD2 to create a safer and more inclusive and innovative European payment system. Amongst the many objectives of PSD2 are to protect consumers when they pay online and to promote the development of an innovative online and mobile payment culture (European Commission, 2015). Collaboration with FinTech presented strategic opportunities despite the initial technical challenges (Brodsky and Oakes, 2017). The implementation of PSD2 presents many worthwhile research possibilities. For example, future studies can investigate if the outcomes envisaged by the regulation have been met. The impact of PSD2 on banks, bank customers and non-banking actors can be better examined through qualitative interviews to contribute to the understanding of the directive's challenges and success factors. Large-scale quantitative data collection through a survey of MFS users/consumers in the EU member countries and beyond can help establish a robust relationship between the implementation success factors and/or barriers and their impact on customer value.
6.6 Open banking and mobile financial services
PSD2 implementation supports open banking. Open banking is a collaborative model in which banking data are shared through an application programming interface between two or more unaffiliated parties to deliver enhanced capabilities to the marketplace (Brodsky and Oakes, 2017). However, while open banking provides enhanced value and benefits to end-users, it also creates data security challenges. Future research in the MFS field can explore the impact of PSD2 on risk, data security and value creation. PSD2 is expected to usher in an entirely new financial service ecosystem and lead to fiercer competition between banks and non-banks, in which banks' roles may shift markedly (Brodsky and Oakes, 2017). Research examining open-banking models in the MFS field and their impact on customer experience is a future-study option.
6.7 Mobile financial applications
The research on the adoption and use of downloadable mobile banking/payment applications (mobile communication technologies are ubiquitous and span a wide range of applications) is highly limited, perhaps overlooked by the previous research. Future studies should consider investigating consumer attitudes towards and behaviour regarding the use of these applications against the backdrop of increased penetration of smartphones and increased use of innovative transactional applications for payment purposes.
6.8 New demographic groups, including millennials, generation Z and generation alpha
Our review showed that the previous studies in the MFS field also focussed on the impact of demographics (e.g. gender differences in MFS adoption/use). The new demographic groups (the millennials, generation Z and generation alpha) allow MFS research regarding such groups' needs, expectations and preferences. Research that also seeks to combine psychological variables with innovation adoption theories to better explain the MFS phenomenon will lead to new insights and will contribute to theory building. For example, the recently developed picky shopper scale (Cheng et al., 2021) differentiates between picky by acceptance and picky by rejection. Future research can integrate the picky shopper scale into studies comparing the shopping behaviours and innovation adoption of generation X, generation Y and the millennials using MFSs as a context.
6.9 Mobile money and the associated challenges
MFSs have seen many innovations and digital transformations in recent years. For example, mobile money (Glavee-Geo et al., 2019; Senyo and Osabutey, 2020) is a form of FinTech innovation that enables financial transactions through mobile services and is a driver of financial inclusion. Unlike formal banking services, mobile money technology relies on an agent network (Glavee-Geo et al., 2019). FinTech is a disintermediation force where disruptive technologies are the main drivers (Das, 2019). While mobile money agents play a vital role in this transformation in most of the countries where mobile money has been introduced, cases of fraud and other exploitative activities have been reported (Akomea-Frimpong et al., 2019). Future empirical studies can investigate the impact of such behaviours (fraud, exploitation) on the adoption and use of mobile money, and its ethical considerations. In addition, the mobile money agents' role as service agents also requires further research, most especially when the actions or inactions of the agents can have a significant impact on the service levels.
6.10 Non-financial value-added services
Much emphasis has been placed on examining the financial aspects of MFSs, and their non-financial aspects have been sparsely examined. Some of these non-financial services are real-time and important account messaging, including service notifications and alerts, which have created a new research domain dealing with non-financial transactions. Nonetheless, very few attempts have been made to consider the importance of non-financial services and the role that they play in providing a greater experience to the consumers. For example, examining the key marketing drivers of consumer experience with non-financial transactions available on mobile banking apps, Shaikh et al. (2020) found that the consumer awareness, usefulness and ease of use of non-financial transactions play significant roles in increasing consumers' sustained use of mobile financial apps. Future research may also examine the effect of the digital notifications in such apps on the attitudes and behaviours of consumers.
6.11 A dedicated scale for mobile financial services
On top of the future research endeavours mentioned in the previous sections, developing dedicated scales for MFSs will benefit both scholarly research and practice when such scales are used in the survey design. The development of dedicated scales for MFSs is thus recommended.
6.12 Mobile financial services and the COVID-19 pandemic
The COVID-19 pandemic has brought about significant disruptions in the social and economic lives of people all over the world. Social distancing, restrictions on mass gatherings and avoidance of physical touchpoints due to the risk of infection have led to a shift from paper-based and other physical touchpoint/contacts (e.g. ATMs) to online transactions. It can be argued that the COVID-19 pandemic has accelerated the digitisation process across the banking, payment and retail sectors. Future research should examine the role played by the pandemic in promoting a digital financial culture. Hence, future studies should consider the impact of the COVID-19 pandemic on digital financial transformation and digitalisation.
6.13 Artificial intelligence (AI)-enabled mobile financial services
The term artificial intelligence (AI) was coined by John McCarthy in 1957 and referred to computers with cognitive skills similar to humans, resulting in immense efficiency gains for firms that use it, and for their clients (Russell and Norvig, 1995). The popular AI tools used in the banking and payment industry include robo-advisors, chat-bots, conversational AI, biometric authentication, call centre agent matching, account management and fraud detection (Mistry, 2018). Despite these motivations, the impact and use of AI in the banking and payment sector have not been studied to date (Deubner, 2021). As such, with the rise of AI, the roles and behaviours of bank and retail customers need to be re-evaluated (Jakšič and Marinč, 2019). Despite the desire of the payment industry to have their customers interact with their AI-enabled solutions, it is unknown if their customers have the desire to do so (Payne et al., 2018), thereby leaving a huge research gap in the examination of such phenomenon. Therefore, future studies in the area of AI-based mobile banking and payment are recommended.
6.14 Artificial intelligence-enabled mobile banking and payment services (AI-MBPSs) and gender disparity
Future research on AI-MBPSs will be consequential if they will also examine gender differences in the adoption and use of AI-MBPSs, especially in countries traditionally considered to have a male-dominated society, with significant gender disparity. Such research may solicit the experiences of female customers when accessing and using AI-MBPSs, thereby providing deep insights into the role of gender in AI-MBPS adoption and use. To the best of our knowledge, no previous study has examined the gender differences in AI-MBPS adoption and use.
