摘要：
An RFID transponder is disclosed in which predetermined conductive portions will be removed from the transponder should the transponder be removed from a first object to which it is attached. The transponder has a first response to applied RF before the predetermined portions are removed and a second response after such removal. An RF detector can be used to scan objects with transponders to detect the first or the second response and thereby determine when a transponder has been moved.
