RFID Applications can be used to monitor and manage the movement of the finished products throughout a supply chain. RFID tags can be attached directly to the items and materials or they can be attached to the containers that carry them. Pallets, trailers, totes, carts, cargo containers, and reusable transport items can all be tagged. Readers placed throughout a facility can monitor movement and location of inventory, thus providing real time data. Since RFID tags can be used to identify each individual item, enormous amounts of location-tracking data are generated. With such data, object movements can be modeled by movement graphs, where nodes correspond to locations and edges record the history of item transitions between locations.
