ABSTRACT:
A transponder apparatus having an identifier associated therewith includes a receiver for receiving an RF signal transmitted by an interrogator, a power source and a processing unit that is operatively coupled to the power source and is capable of being in an inactive, sleep state (low current draw) and an active state. The transponder apparatus also includes a buffer device that is structured to: (i) receive an information signal based on the RF signal from the receiver, (ii) determine whether the information signal includes the identifier, and (iii) cause the processing unit to move from the inactive state to the active state and transmit at least a portion of the information signal to the processing unit only if it is determined that the information signal includes the identifier. An associated method is also provided.
