Abstract
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. The method comprises receiving a first hailing radio signal in a first frequency band by an application executing on a processor of an RFID chip, in response to receiving the first radio signal, transmitting a first tier of information stored in the RFID chip in the first frequency band by the application, receiving a second hailing radio signal in a second frequency band by the application, and, in response to receiving the second radio signal, transmitting a second tier of information stored in the RFID chip in the second frequency band by the application.
