Abstract:
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.
