PROBLEM TO BE SOLVED: To provide a technique for managing prepaid points which are usable at a plurality of stores.
SOLUTION: A user 50 deposits money in a deposit account 24 corresponding to a point ID. A control part 16 once confirming the deposit in the deposit account 24 issues corresponding prepaid points and adds them to a common point storage part 10. The user 50 is able to move them to individual prepaid points which are usable only at a specified store. The control part 16 subtracts the moved points from the common point storage part 10 and adds them to a store-A individual point storage part 12 and a store-B individual point storage part 13. Further, transfer of the amount corresponding to the moved points from the deposit account 24 to a store-A account 32 and a store-B account 42 is indicated.
