Abstract
An RFID apparatus for communicating with at least one RFID transponder is provided that has an RFID transceiver for radiating and receiving RFID signals and a control unit that is configured to encode RFID information into the RFID signal in accordance with an RFID protocol or to read it from the RFID signal and in which a singulation process is implemented to give a command to only one respective RFID transponder. The singulation process in this respect checks a communication parameter of the RFID signal itself that is independent of RFID information encoded in the RFID signal.
