Abstract
Provides protection to wireless portable transponders from an unauthorized interrogation by employing a mechanical member. Transponders include: cards, fobs and RFID tags that a persons may carry. Such transponders generally have means for receiving and storing electronic and other information, commonly in binary form using memories as in electronic circuits, etc. The invention is designed to provide privacy of electronic information and yet permit the information to be queried at the users discretion. The cards and tags can be protected from receiving or providing unauthorized or unwanted information. The invention provides the mechanical member with means that permit the owner to decide when reception/interrogation of personal or other information is desirable by employing the provided mechanical enable/disable control means.
