ACOUSTIC WAVE AND RADIO FREQUENCY IDENTIFICATION DEVICE AND METHOD
First Claim
1. A wireless identification method comprising:
- receiving at an acoustic wave and radio frequency identification device an acoustic wave signal of a first frequency and a radio frequency signal of a second frequency, wherein the acoustic wave signal and the radio frequency signal are received from an acoustic wave and radio frequency identification reader, and the first frequency and the second frequency are different frequencies; and
responding to the receiving by transmitting at least one of an acoustic wave identification (AWID) or a radio frequency identification (RFID) from the acoustic wave and radio frequency identification device.
