ABSTRACT:
A device for deactivating an RFID portion on an identification tag and indicating that the RFID portion is deactivated. The present invention addresses current privacy concerns regarding potential use of RFID technology after the point of sale. The device for deactivating the RFID portion of an identification tag provides visual indication that the RFID portion is deactivated. The visual indication occurs without the use of additional equipment or electronics. The visual indication component of the present invention is easy to interpret, so that a viewer will be able to quickly determine whether the RFID portion of the identification tag has been deactivated.
