The present invention relates to a payment processing system. The present invention comprises: a wireless terminal for receiving resident registration number from a purchaser when a purchase order is inputted for a certain product by the purchaser through an app, and for requesting payment process based on the purchase order with a corresponding key - which is a key for producing encoded sentence for resident registration number inputted by the purchaser - and a service server - which is a server providing services corresponding to the app; and the service server for producing the corresponding key when the corresponding key request is received from the wireless terminal through a communications network and for transmitting the same to the wireless terminal. The wireless terminal, using the corresponding key received from the service server, produces the encoded sentence encoding the resident registration number. Also, the wireless terminal transmits the encoded sentence to the service server in a message oriented (MO) method. The service server processes the payment for the payment request of the purchaser if the phone number of the wireless terminal outputting the encoded sentence in the MO method is identical to the phone number of the wireless terminal requesting the corresponding key. |
