<p>To provide an improved management structure of memory devices storing service-use applications. A card for a memory device applied to use various services is provided as one child card or more corresponding to each of the services, a parent card stores data for child-card issue management, and the child-card issue processing is executed based on the parent card, such as parent card authentication. An issue certificate having a parent-card digital signature is stored in the child card, the issue certificate contains a service code and a child-card identification, and thus it becomes possible to confirm a service set in the child card based on the issue certificate as the parent-card signature data. <IMAGE></p> |
