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.
Claims15
An RFID apparatus for communicating with at least one RFID transponder, the RFID apparatus comprising:
- 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 a singulation process is implemented in the control unit, with the singulation process being adapted to give a command to only one respective RFID transponder,
- wherein the singulation process checks a communication parameter of the RFID signal itself that is independent of RFID information encoded in the RFID signal.
A method for communicating with at least one RFID transponder, wherein RFID signals are transmitted to the RFID transponder and are received by the RFID transponder, wherein RFID information is encoded in the RFID signals in accordance with an RFID protocol, and wherein a command is given to only one respective RFID transponder on the basis of a singulation process,
- wherein the singulation process checks a communication parameter of the RFID signal itself that is independent of RFID information encoded in the RFID signal.
