Abstract
An arrangement for providing protection to wireless portable transponders (including resonant tags such as RFID tags) from unauthorized interrogation by employing a mechanical means 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 means that permit the owner to decide when reception/interrogation of personal or other information is not desired by employing the provided mechanical disable control means. 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.
Claims32
A method of altering interrogation characteristics of a resonant tag, said method comprising the steps of:
- obtaining a resonant tag, the resonant tag comprising an antenna;
- and
- reducing a read range of the resonant tag via physically compromising at least a portion of the antenna of the resonant tag.
A resonant tag kit comprising:
- a resonant tag;
- said resonant tag comprising an antenna;
- and
- an arrangement for reducing a read range of said resonant tag via physically compromising at least a portion of said antenna.
A method of assembling a resonant tag kit, said method comprising the steps of:
- providing a resonant tag, the resonant tag comprising an antenna;
- and
- providing an arrangement which reduces a read range of the resonant tag via physically compromising at least a portion of said antenna.
