A

To enable users to enjoy a plurality of services when there are a plurality of identification information.

The identification information UID read out of an optical disk is sent to the side of a server for management and the users can enjoy the contents for services prepared on the side of the server for management by as much as the number of pieces of the identification information. The users are able to judge a finite number of the services only by the number of pieces of the identification information. The contents ought to receive the services are the same contents or the contents different at every service. If the management of the number of service times is performed on the side of the server for management, the number of the service times etc., are eventually managed by referencing the identification information UID read out of the optical disk and therefore the management does not depend on an information terminal device for reproducing the optical disk at all.
