A mobile communication terminal includes a communication unit, a wireless communication unit, a contents acquisition unit, a contents storage unit, a verification unit, and an output permission determination unit. The communication unit communicates with an IC card. The wireless communication unit provides wireless communication using user information stored in the IC card. The contents acquisition unit acquires contents using the user information. The contents storage unit stores the contents in a form so as to be associated with user identification information acquired from the IC card. The verification unit verifies whether or not the user identification information acquired from the IC card matches the user identification information, which is stored in the contents storage unit so as to be associated with contents to be outputted. The output permission determination unit determines whether or not output of the contents should be permitted, receiving verification results obtained by the verification unit.
