Abstract
The claimed invention is directed to a contactless card, an inlay for a contactless card or a circuit embedded within a contactless card containing a radio frequency identification ('RFID') circuit that is only actuated when the card is flexed. The RFID circuit comprises an antenna comprising a first conductive lead, a second conductive lead; and an RFID chip connected to the antenna. A dielectric layer having an aperture is embedded in between the antenna and a bridge, the aperture in the dielectric layer being situated between the first conductive lead and the second conductive lead of the antenna. Normally, the bridge is biased away from the first conductive lead and the second conductive lead. When the card is flexed, the bridge is biased into contact with the first conductive lead and the second conductive lead thereby completing the circuit.
