1. 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, reads the generic identity from the non-transitory memory and causes the radio transceiver to transmit the generic identity on the first frequency band,
detects via the radio transceiver radio signals in the first frequency band,
stores information about the radio transceiver radio signals in the first frequency band in the non-transitory memory,
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,
in response to the second query for identity, reads the unique identity from the non-transitory memory and causes the radio transceiver to transmit the unique identity on the second frequency band,
receives a request to upload stored information from the radio transceiver received on the second frequency band, wherein the request to upload provides the unique identity,
in response to the request to upload stored information, reads the information about the radio transceiver radio signals in the first frequency band from the non-transitory memory and causes the radio transceiver to transmit the information stored about the radio transceiver radio signals in the first frequency band read from the non-transitory memory on the second frequency band, and
after transmitting the information stored about the radio transceiver radio signals, deletes the information about the radio transceiver radio signals in the first frequency band from the non-transitory memory.
