Abstract
At a mobile terminal apparatus provided with a non-contact IC, flexible communication is carried out between the external reader/writer , non-contact IC and the internal application manager controller, and a program designated in the form of a push from the external reader/writer is activated and executed in a smooth manner at the mobile terminal apparatus. Normally, the non-contact IC cannot communicate with the application manager controller during communication with the external reader/writer, and cannot communicate with the external reader/writer during communication with the application manager controller. A specific command is transmitted from the external reader/writer together with information specifying a prescribed application during communication between the external reader/writer and the non-contact IC. When the specific command is received, the non-contact IC shifts to a communication state enabling communication with the application manager controller. The application manager controller captures and executes information specifying the application at the timing of the transition.
