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.
