Abstract
A smart card stores secure data, such as monetary values, and selectively transfers the secure data to or receives the secure data from a compatible smart card. The smart card includes a data storage device that stores the secure data. An identification input system receives identification input from a user. Control circuitry is responsive to the identification input to transfer secure data into the data storage device from a compatible smart card or to transfer secure data out of the data storage device to a compatible smart card when the control system determines from the identification input that the transfer is authorized. A data transfer interface in an edge of one card couples directly to a like interface in a slot of the other card to enable the secure data to be transferred between the two cards when the two cards are moved relative to each other.
