Abstract: Reading data from, writing data to and storing data in an IC card, utilizing an external Read/Write unit. An IC card (12) is provided. The IC card (12) comprises a rigid substrate (86) and electrical components (88) disposed on the substrate. A card coil (32) is provided about the periphery of the substrate (86) and is placed in a coil form (94). Card capacitive plates (24) and (26) are disposed on the bottom of the substrate (86). Power circuitry is provided for receiving inductive power from the card coil (32) and generating a regulated power supply voltage for powering the electrical components (88). I/O circuitry is provided for capacitively coupling data via the card capacitor plates (24) and (26). A cover (130) is also provided for covering the electric components (88) on the substrate (86). An IC card Read/Write unit (14) is provided. The IC card Read/Write unit comprises a receptacle (16) shaped similar to the substrate (86) of the IC card (12).
