摘要

Systems (100) and methods (300) for selective device responsiveness using a plurality of control tags (132) affixed to a plurality of objects (102). The methods involve: receiving, by a plurality of control tags, a reporting command signal sent from an interrogation device via a communications link; and communicating a response to the reporting command signal from only those of the plurality of control tags which are (1) currently being moved, (2) have been moved within a first specified period of time, and/or (3) have a surrounding environment with at least one characteristic that has recently changed.
