SOLUTION: A customer (user terminal part) G establishes and registers the account of a financial institution B through a certification server (storage agency) D. A contract is made among a non-life insurance company, the certification server D and the customer G for securing the credit of a contract joining store S when debt is not fulfilled. The insurance company adds 2% to commodity price and the certification server D receives the transfer charge of one hundred and several ten yen, for example. The contract joining store S recognizes the existence of ID/password of the customer through the certification server D by receiving the will of the payment of commodity price by the customer.
