A server includes a database that stores, in association with user identification information for identifying the user who purchases or uses goods or services, the number of points that are assigned to the user according to the purchased or used goods or services and that can be used to purchase goods or services. The server divides the points stored in association with the user identification information into user's own points that only the user can use; and other's points that other users other than the user can use, before storing the points in the database. |
