The invention relates to a method for recognizing temporally variable functional states, e.g. in the course of a programming process, in RFID systems comprising at least one transponder or remote sensor and at least one base station which transmits data and/or power to the transponder or sensor by means of a carrier signal. According to the invention, at least one receipt symbol is transmitted by the transponder or sensor to the base station upon reaching a predetermined process state. As a consequence, no unfavourable worst case scenario has to be provided for chronologically controlling temporally variable processes because the base station is able to clearly recognize the beginning and end of the process as well as the state thereof. RFID systems or remote sensor systems can thus be controlled more quickly and more securely, resulting especially in reduced costs.
