A non-contact IC can exchange information with a reader/writer by wireless communication. When the non-contact IC receives from the reader/writer a command indicative of restricting use of the non-contact IC, the non-contact IC sets itself in a state of restricted use. When in the state of restricted use, the non-contact IC can not exchange information with a reader/writer.

By concealing the existence of an area using a function (which is referred to as IC privacy function) capable of concealing the data area corresponding to each service (behaving as if the data area does not exist), an existing function provided in the contactless IC card, an access to the data necessary for a service can be inhibited, so as to control to inhibit (lock) use of the contactless IC card on a service-by-service basis.
