PROBLEM TO BE SOLVED: To carry out desired dealings with a sense of security. SOLUTION: When receiving the conditions of certain desired dealings from a customer computer (YES in S350), a server determines the reliability of a customer who has written the desired dealings, on the basis of the amount of credit line (S360). If reliable (YES in S360), the desired dealings are registered unless the same item with advantageous conditions is notified (S380-S430), and thereafter the desired dealings are notified on an electronic bulletin board not as the one belonging to the customer but as the one presented by a bank that is a server manager. |
