Abstract
This invention relates to a transaction processing system including a host computer (1), a transaction device (2), a first customer card (3) and a second customer card (4). The first card (3) and the second card (4) directly transfer information representing monetary values between them on the basis of signals verifying a transaction processing received from the host computer (1) through the transaction device (2). When the information representing the monetary values are exchanged between the first card (3) and the second card (4), the host computer (1) updates the balance of the account stored in the host computer (1).
