PURPOSE: A method for paying a price using a purchase card is provided to pay a commodity price without an additional payment terminal by reading information of a purchase card and a supplier ID card through a credit card terminal mounted in a store of a commodity purchaser, and executing an account transfer from an account of the purchaser to an account of the supplier. CONSTITUTION: Card information is read through a credit card terminal mounted in a purchase store(S10). It is judged whether the card is a purchase card(S20). If the card is a purchase card, card information of a supplier ID card is read(S30). Transaction details are received for paying a commodity price(S40). An account transfer is requested to a bank business processing system(S50). The bank business processing system executes an account transfer(S60), transmits processing results to a taxation business server, and transmits an account transfer result to the credit card terminal(S70). The account transfer processing result is received from the bank business processing system(S80).
