METHOD FOR OFFERING PAYMENT SERVICE ON PDA USING ACCUMULATED MONEY

摘要

PURPOSE: A method for offering a payment service on a PDA(Personal Digital Assistant) using accumulated money is provided to improve a use degree of the accumulated money and the PDA, by supplying a coupon and a bar code to the PDA, and enabling payment of a product and service using the coupon and the bar code. CONSTITUTION: The coupon and the bar code are displayed on the PDA(S500). A clear button on the PDA is clicked so that validity of the coupon and the bar code can be checked(S501). When the clear button is clicked, the PDA is connected to a web server automatically(S502). The web server determines whether the coupon and the bar code are valid(S503). If the coupon and the bar code are not valid(S504), this information is sent to the PDA(S505). If the coupon and the bar code are valid and thereby the payment of the product is made, a code number database is updated(S506). A payment money database of an allied company is also updated(S507). A used coupon is deleted from the PDA automatically after the payment(S508).
