Abstract
A transaction processing system using a prepaid microchip card includes a customer's microchip card reader/writer for communicating with a customer's microchip card in which a balance is recorded, and a vendor's microchip card reader/writer that can be electrically coupled to the customer's microchip card reader/writer and is used for communicating with a vendor's microchip card in which a balance is recorded. A transaction is processed by deducting the amount of the transaction from the balance in the customer's microchip card and adding this amount to the balance in the vendor's microchip card.
