1. A container assembly in a system for tracking at least one radio frequency identification tag, comprising:
- (a) a container having a container body;
(b) a first radio frequency signal transmitter of the at least one radio frequency identification tag associated with the container, wherein the first radio frequency signal transmitter is capable of transmitting a first radio frequency signal; and
(c) a second radio frequency signal transmitter of the at least one radio frequency identification tag associated with the container, wherein the second radio frequency signal transmitter is capable of transmitting a second radio frequency signal different at least in part from the first radio frequency signal, wherein the first and second radio frequency signals transmit at different signal frequencies, wherein the first radio frequency signal carries identification data and the second radio frequency signal carries tracking data, and wherein the first and second radio frequency signals transmit at different signal strengths.

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.
