Abstract:
An apparatus (such as but not limited to an RFID tag) includes an RFID transceiver that is configured to automatically switch from a readable state to a quiescent read state upon being read and to remain in the quiescent read state at least while provisioned with reader-based power. The apparatus further includes a read-state changer disposed locally with respect to the RFID transceiver and configured to switch the RFID transceiver from the quiescent read state to the readable state notwithstanding current availability of the reader-based power.
