Abstract:
1. An inventory tracking system comprising: a multi-directional RFID reader positioned along a passageway connecting a product storage area and a retail floor area, wherein the RFID reader includes a plurality of multiple directed sensors, wherein each of the plurality of multiple directed sensors is directed to detect along the passageway presence of an RFID tag associated with a product at multiple discrete positions as the product and the associated RFID tag travel along the passageway, and wherein said RFID reader has a time stamp function operable to assign a time stamp to each discrete detection of the multiple discrete positions detected; a background server communicably connected to the RFID reader, wherein the RFID reader includes a transmit function operable to transmit to the background server RFID detections, sensor identifications and associated time stamps; and an executable inventory control application operably residing on the background server, wherein when executed, the inventory control application determines a direction of travel of the product and the associated RFID tag based on RFID transmissions.
