A system for determining movement of an item bearing an RFID label. The system includes an RFID reader for receiving RFID label identification information from an RFID label associated with the item, and a computer for determining a location of the RFID label and the item by determining location information for the RFID reader, for determining a preferred location for the RFID label and the item, and for comparing the determined location with the preferred location to determine that the RFID label and the item have been moved.
