1. A radio frequency identification (RFID) device comprising:

  • an RFID tag configured to store identification information;

    an antenna configured to support radio frequency (RF) communications;

    circuitry coupled to the antenna and the RFID tag, the circuitry configured to send and receive RF communications using the antenna;

    a display configured to present an output of a timer;

    an activation mechanism comprising a first electrical contact and a second electrical contact, the activation mechanism disposed in the RFID device such that;

    in a first configuration of the activation mechanism, the circuitry is electrically connected to the antenna through the first and second electrical contacts to enable RF communications using the antenna, andin a second configuration of the activation mechanism, an electrical connection between the antenna and the circuitry through the first and second electrical contacts is insufficient for supporting RF communications through the antenna,wherein placing the activation mechanism in the first configuration initiates the output of a timer on the display; and

    a deactivation mechanism comprising a switch disposed between the antenna and the RFID tag, the deactivation mechanism being separate from the activation mechanism, and disposed in the RFID device such that;

    in a first configuration of the deactivation mechanism, the switch connects the RFID tag to the antenna such that the identification information can be stored in or read from the RFID tag by an external device, andin a second configuration of the deactivation mechanism, the switch creates an electrical separation between the RFID tag and the antenna such that the identification information stored in the RFID tag is undetectable to an external device.
