A system for processing credit card payment on a TRS(Trunked Radio System) network is provided to inquire a credit card at a lower communication charge than a usual mobile credit card terminal operated in a CDMA(Code Division Modulation Access) environment, and offer convenience of a general phone function and an interphone call between mobile payment phones. A mobile payment phone(100,100n) provides a phone function in a TRS network environment, reads card information from a magnetic stripe of a credit card, and receives a signature through a sign pad embedded in a display unit. A payment management server(200) stores sign information received from the mobile payment phone and a card approval number received from a financial server(500) by connecting to a central switch station(400). A relay station(300) connects the mobile payment phone and the central switch station. The central switch station connects a phone network(600) or a financial network by analyzing information requested from the mobile payment phone. The financial server determines approval by analyzing the credit card information received from the mobile payment phone. The phone network provides a phone service when the mobile payment phone is in a phone mode. |
