Abstract
According to an aspect the present invention provides an RFID method to collate a set of objects. According to various aspects the method includes using an interrogator to radiate a field of radio-frequency energy to a correlated set containing at least a first object-transponder pair, energizing an ASIC portion of a transponder using energy received by said at least one transponder, and initializing the ASIC, and broadcasting an identity signal therefrom. According to an aspect, the interrogator an antenna and a unique ASIC.
Claims6
An RFID system comprising:
- an interrogator comprising a microcontroller, a transmitter, a frequency modulator, a receiver, and a single antenna;
- and a correlated set containing a plurality of first object transponder pairs, wherein each said first object transponder pair comprises an antenna and a unique ASIC;
- and wherein the interrogator generates a plurality of unique interrogation signals, each of the plurality of first object transponder pairs being responsive to one such unique interrogation signal.
