A method for managing payment tools is provided to enable a member shop to make a purchase contract with customers and enable the customers to receive more incentive from the member shop compared to non-contracted customers by enabling a credit card company or a financial company to make the purchase contract with the customer without high cost marketing. A server links/stores settlement tool information and contract information to a storage medium(205). The server calculates total contracted purchase data by reading contracted purchase data from the storage medium and summing up the read contracted purchase data(220). The server stores incentive data, which is provided to the contracted customer according to the calculated total contracted purchase data, to the storage medium by linking with the settlement tool information of the customer(245). |
