Multi-tier identities in an RFID chip

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.

A method of transmitting a first tier of information by a radio frequency identity (RFID) chip when hailed in a first frequency band and transmitting a second tier of information by the RFID chip when hailed in a second frequency band, comprising:

• receiving a first radio signal in a first frequency band by an application executing on a processor of a radio frequency identity (RFID) chip, where the first radio signal hails the RFID chip to transmit information;
• in response to receiving the first radio signal in the first frequency band, transmitting a first tier of information stored in the RFID chip in the first frequency band by the application;
• receiving a second radio signal in a second frequency band by the application, where the second radio signal hails the RFID chip to transmit information;
• and
• in response to receiving the second radio signal in the second frequency band, transmitting a second tier of information stored in the RFID chip in the second frequency band by the application, wherein the second tier of information contains different information than the first tier of information contains.
