Patent ID: 8230233

Claim:
An information processing terminal comprising: a first IC card chip constituted by a first control unit, a first storage unit configured to store applications to be processed by said first control unit, a first encryption unit configured to encrypt data created by any of the applications in said first storage unit before outputting the created data outside the chip, and a wireless control unit configured to permit noncontact wireless communication with a reader/writer; a second IC card chip constituted by a second control unit, a second storage unit configured to store applications to be processed by said second control unit, and a second encryption unit configured to encrypt data created by any of the applications in said second storage unit before outputting the created data outside the chip; a terminal control unit configured to control data communication between said first IC card chip and said second IC card chip; wherein said first control unit is configured to only execute low-load applications of which a processing load involved in data communication with said reader/writer is less than a predetermined level, without intervention of said second IC card chip and said terminal control unit, and said second control unit is configured to execute only applications of which the processing load is above the predetermined level, and wherein low-load applications are loaded from said second storage unit into said first storage unit in accordance with a load command issued by said terminal control unit.
