Patent ID: 10546286

Abstract:
The purpose of the present invention is to transfer value, the balance of which is managed by a server, to a terminal that does not have online connection function. An electronic money server 2 records the balance of a value in a state in which the balance is related to an electronic money card 4 or a portable terminal 5. An off-line payment terminal 7 is not provided with communication network connection function and cannot communicate with the electronic money server 2 directly. On the other hand, the portable terminal 5 can connect to the electronic money server 2 via the Internet 3. Thus, the off-line payment terminal 7 connects to the electronic money server 2 by using the portable terminal 5 as a relay device by using the communication network connection function of the portable terminal 5 at the time of payment. In this way, the electronic money server 2 can connect to the off-line payment terminal 7 and make payment by using the value of the account of the portable terminal 5.
