Communication Device and Communication Method

摘要

The objective of the present invention is to provide a data processing apparatus that can employ together application programs for both a portable telephone and a contactless card terminal and that can communicate with an external device in accordance with a predetermined protocol by using, as needed, an appropriate-application program, and a data processing method that uses this data processing apparatus. A hybrid portable communication terminal, which serves as a data processing apparatus and comprises terminals having different communication systems, can employ together or selectively, as needed, an application program for a telephone terminal and an application program for performing various data processing procedures, with an external communication terminal, using close-range contactless communication.
