PURPOSE: A payment processing system and a control method thereof are provided to process payment by using a special key corresponding to each transaction server, thereby not influencing other transaction servers even if a special key for one transaction server is leaked. CONSTITUTION: A credit evaluation management server(200) generates and stores a special key. The credit evaluation management server transmits the generated special key and a client unique ID to a transaction server(400). The credit evaluation management server provides client authorization identification information corresponding to the special key when information conversion about the special key is requested. A payment processing server(100) processes payment using the client authorization identification information. |
