ABSTRACT:
Systems and methods are disclosed for a tamper resistant RFID (radio frequency identification) tags that overcome the problems existing with previous RFID tags. The tamper resistant RFID tags described herein are particularly useful for tracking of liquid propane gas (LPG) containers and/or other types of containers or objects. Removal of the RFID tag, after it is attached, will destroy and/or render inoperable the RFID transponder within the tag so that removal and re-use is not practical or possible. One key feature of this tamper resistant RFID tag is the use of adhesive materials with differing adhesion characteristics with respect to the container material (e.g., metal) and the housing for the RFID tag (e.g., plastic) so that the RFID tag will tend to be destroyed when removal is attempted.
