System and Method for providing payment service of pre-paid card used-fare based on open interface using portable communication terminal

摘要

A system and a method for providing a prepaid card payment service based on an open interface using a mobile terminal are provided to enable a user to safely and easily pay a taxi fare by using the open interface provided from a telecommunication provider. A billing server(200) stores/manages account information of an SP and the user. A user mobile terminal transmits payment approval information inputted by responding to taxi fare payment request information. An SP mobile terminal transmits a fare payment request signal including a mobile number of the user mobile terminal according to service use of the user. Each open service application server(520,540) transmits the payment request information if the payment request signal is received, and transmits a payment request signal if the corresponding payment approval information is received. An open service gateway(400) transmits the received payment request information to the user mobile terminal and processes taxi fare payment by withdrawing an amount from the billing server according to the payment request signal.
