Abstract
A server receives a card ID of a credit card, a credit amount, and a terminal ID for identifying a shop terminal from a shop terminal. The server acquires a corresponding user ID from the card ID, to find out whether this user has approved that location information can be acquired from his/her mobile terminal. In the case where the user has approved that location information is acquired in advance, the server acquires a mobile phone number from the user ID, to know a location of the mobile terminal with use of this mobile phone number. The server acquires a shop ID from the terminal ID (fixed-line telephone number) of the shop terminal, to be able to acquire a shop location from the shop ID. The server compares the location of the mobile terminal and the location of the shop, to judge whether or not conformance is made.
