Abstract:
The present disclosure is directed to a system and method for tracking tampered with RFID tags. In some implementations, an RFID tag includes a tearable substrate including at least a portion of an RFID circuit. The portion of the RFID circuit is substantially destroyable in response to at least an attempt to remove the tag from a surface. In addition, the RFID includes an adhesive layer adjacent at least a portion of the tearable substrate and configured to affix the tag to the surface.
