SYSTEM AND METHOD FOR PROCESSING PAYMENT ADMISSION OF CHECK CARD BY USING RELAY SERVER AND RECORDING MEDIUM

摘要

A system and a method for processing a payment approval of a check card by using a relay server, and a program recording medium thereof are provided to increase usability of a check card and a security account of a security company by using a relay server between a credit card company and the security company. A check card management server(1740) generates and transmits a debit payment approval request message including check card information and debit payment amount information to the relay server(1700) by receiving a check card approval request message. The relay server reads whether the payment account according to the check card is a bank or security company card by reading the check card information from the received message, and checks a balance of the read account by linking with an account management server(1770). The relay server determines availability for debit payment corresponding to a debit payment amount, and generates and transmits an approval response message corresponding to a determination result to the check card management server.
