ABSTRACT:
An apparatus and method for providing a radio frequency identification (RFID) card, the card including a card inlay; an antenna positioned on the card inlay, a RFID integrated circuit (IC) on the card inlay, a pressure-sensitive switch including an electrode structure located on or in the card inlay and coupled to the antenna and the RFID IC via the electrode structure, the pressure-sensitive switch having an electrical resistance that varies with a pressure applied to the switch, and a dam of material in a vicinity around of the pressure-sensitive switch to provide a barrier against a lateral pressure being applied to the switch.
