ABSTRACT:
A container assembly for tracking a radio frequency identification tag (20) generally includes at least one container (22), an RFID tag (24) associated with the container, and an RFID signal transmitter (26) associated with the radio frequency identification tag. The RFID signal transmitter is capable of transmitting an RFID response signal (1044). The assembly further includes a tracking signal transmitter (28) associated with the RFID signal transmitter. The tracking signal transmitter is capable of transmitting a tracking signal (1046), and the tracking signal is different at least in part from the RFID signal.
