Classification: CPC G  H | IPC G  H

Claim 7:
8. A radio frequency identity (RFID) chip, comprising:
a processor;
a radio transceiver communicatively coupled to the processor;
a non-transitory memory that stores a generic identity shared with a plurality of other RFID chips and a unique identity that is not shared with other RFID chips; and
an application stored in the non-transitory memory that, when executed by the processor:
receives a first query for identity from the radio transceiver received on a first frequency band by the radio transceiver,
in response to the first query for identity being received on the first frequency band, reads the generic identity from the non-transitory memory and causes the radio transceiver to transmit the generic identity on the first frequency band,
receives a second query for identity from the radio transceiver received on a second frequency band by the radio transceiver, where the second frequency band is different from the first frequency band, and
in response to the second query for identity being received on the second frequency band, reads the unique identity from the non-transitory memory and causes the radio transceiver to transmit the unique identity on the second frequency band.
