<p>A mobile tag reader (3) and method for tracking tags (2) for an inventory control and/or security of distributed assets. Radio frequency identification (RFID) tags (2) may be attached to stationary or moveable assets and communicate with one RFID tag readers (3, 11). The communication may provide information to a central or remote controller (10) about the identity, position and/or the status of the tags (2) and assets. The absolute positions of the tagged assets may be determined by the mobile tag reader (3) or central controller (10), and the absolute position of the mobile reader may be ascertained from communications with tags in fixed known locations. Typical applications are for indoor inventory control with the mobile tag readers being mounted to roving trucks, forklifts, or being carried by personnel.</p> |
