ABSTRACT:
An arrangement for providing protection to wireless portable transponders (including resonant tags such as RFID tags) from unauthorized interrogation by employing a mechanical arrangement for disabling reception by or from the antenna of the transponder. The tags can be protected from receiving or providing unauthorized or unwanted information. Contemplated are mechanical arrangements that permit the owner to decide when reception/interrogation of personal or other information is not desired by employing the provided mechanical disable control arrangement. Also broadly contemplated herein is the altering interrogation characteristics of RFID tags to such an extent that they may still be read at a close range instead of the original range, and this result of this altering is visible to the user.
