Abstract
A smart card stores monetary values and selectively transfers monetary values to and receives monetary values from a compatible smart card. The smart card includes a data storage device that stores data representing monetary values. Control circuitry controls the transfer of the monetary values into the data storage device and controls the transfer of the monetary values out of the data storage device. A data transfer interface couples directly to a like interface on the compatible card to enable data to be transferred between the smart card and the compatible card. A system for electronic transfer of monetary values includes first and second smart cards. Each of the first and second smart cards includes a data storage device that stores data representing monetary values.
