ABSTRACT:
An identification protocol that includes multiple identification methodologies is used to isolate and identify a radio frequency (RF) transponder. In accordance with a preferred embodiment of the present invention, the RF transponder includes a memory device, an RF front end, a random number generator (RNG), a counter, and a signal processing circuit connected thereto and programmed to operate in accordance with an identification protocol (or portions thereof). If multiple RF transponders are transmitting their ID numbers simultaneously, the radio frequency identification (RFID) base station may chose to resolve these conflicts later by transmitting the {a} Next_Cycle command, which moves the transponders back to a ready state. Alternatively, the {a} Fail command can be used to isolate and identify individual RF transponders. Once the transponder is isolated, it can be acknowledged and/or move to a 20 data_exchange state by transmitting a Read_New, FAK, PAK or AAK command, each one having unique characteristics.
