PURPOSE: To provide a credit transaction management system which informs a credit card user of the interest and service charge at the time of transaction processing. CONSTITUTION: A terminal device 1 generates transaction data on the amount of the transaction and data for authentication including the card number, etc., of a card used for the transaction and sends them to a terminal controller 2. The terminal controller 2 sends the data for authentication to a CAFIS5 through a network and calculates the interest and service charge in a payment method included in the data for authentication from an interest management file upon receiving transaction permission as the authenticated result, thereby sending it to the terminal device 1. The terminal device 1 issues a transaction slip on which the interest and service charge regarding the credit transaction are printed. |
