1. An apparatus comprising:

  • a radio-frequency identification (RFID) transceiver configured to automatically switch from a readable state to a quiescent read state upon being read and to remain in the quiescent read state while provisioned with reader-based power but to automatically revert from the quiescent read state to the readable state upon losing reader-based power for at least a particular length of time and then being re-powered with reader-based power;

    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, the read-state changer including;

    a control circuit configured to switch the RFID transceiver from the quiescent read state to the readable state; and

    a user interface that operably couples to the control circuit, such that the control circuit responds to a user assertion of the user interface by switching the RFID transceiver from the quiescent read state to the readable state.
