ABSTRACT:
A method to secure RFID card information consisting of a piezo electric element coupled to a transistor which is coupled across the antenna leads of a RFID tag, the transistor provides a short circuit or and open circuit across the antenna leads or antenna input leads of a the RFID chip. The transistor when not energized provides a short circuit on the RFID antenna. When the transistor is energized by a piezo electric element the short circuit is removed and the RFID chip can transfer data normally. Furthermore, the present invention includes a single integrated circuit package, being a single integrated transistor RFID chip package based on the transistor circuit design to operate specifically with a piezo electric element when used with a RFID tag.
