Abstract
A delivery service providing system includes an entrance and exit control unit, an identifier control unit, and a delivery service providing unit. The entrance and exit control unit inputs a ticket identifier of a user who has entered or exited a predetermined area and transmits the identifier to the identifier control unit. The identifier control unit registers the ticket identifier to a database and erases the ticket in case of exit. The identifier control unit receives an identifier set of a ticket identifier and a user's unit identifier from a user's unit, checks to judge whether an identifier set matching the received identifier set in the database. If the result is positive, the delivery service providing unit delivers digital contents to the user's unit. It then becomes possible to provide only the users existing in the area with the contents deliver service.
