Patent ID: 7916025

Claim:
A system for tracking the location of an object, the system comprising: an object tag comprising: an RFID device capable of storing object identification data; and a first RF transceiver device capable of accessing the stored object identification data and capable of establishing a network for the exchange of digital data with other object tags having same capabilities, wherein the networked object tags exchange at least a portion of the object identification data; and an operator tracking device comprising, a visible or audible notification device; and a second RF transceiver capable of wirelessly interfacing with the object tag RFID device and the first RF transceiver device, wherein the interfaced device is sensitive to the proximity of the tracking device, causing a corresponding visible or audible notification of the object tag's proximity to the tracking device; wherein the RFID device is passive and the first RF transceiver device is active, wherein the operator tracking device detects the active RF transceiver device at a first distance from the object tag, and the operator tracking device detects the passive RFID device at a second distance from the object tag, the second distance being within the first distance; wherein the network established between said object tags allows an operator using said operator tracking device to wirelessly interrogate an object tag attached to an object container to remotely examine the container's contents.
