摘要

When a management computer accepts a request for giving points from a giving source, the management computer confirms the expiration date of points of the giving source user, by referring to a user database that stores information of the number of points that a user has, and the expiration date of the points that the user has. The management computer accepts designation of a giving number of points and giving destination user from the giving source user, in a case where the expiration date of points of the giving source user has not passed. The management computer subtracts the designated giving number of points from the number of the points of the giving source user, stored in the user database, and adds the giving number of points to the number of points of the giving destination user, stored in the user database.
