An RFID device tester includes coupling elements for capacitively coupling a reader to an RFID device to be tested. The reader may power the RFID device by sending an outgoing signal, such as an outgoing AC power signal, which may be rectified and/or reflected by the RFID device, if the RFID device is operating properly. The outgoing signal may have a frequency that is different from the resonant frequency of an antenna of the RFID device. A reader in the RFID device tester detects the reflected and/or transmitted signal to confirm proper operation of the RFID device. The RFID device tester may be used as part of a roll-to-roll process, to individually test RFID devices on a roll of material. By utilizing short-range capacitive coupling, difficulties caused by simultaneous activation of multiple RFID devices may be reduced or avoided.
