Abstract
A personal memory card the size of a standard plastic credit card is usable in a variety of applications, from custom repertory dialing to storage of individual medical and/or banking records. Although the card looks and feels much like an ordinary credit card, the personal memory card includes a computer, an electrically erasable field-programmable read-only memory and also circuitry for inductively receiving a power signal and capacitive transferring data signals between the card and a card reader/writer located in an associated station. No direct ohmic electrical contact is made between the card and the reader/writer for transferring power to the card or for transferring data to and from the card. The card is also reprogrammable by the associated station with new and different data as desired.
