In the present embodiment, even when a hands-free device other than a genuine product and a conforming standard product is connected to the mobile terminal device 70, the non-contact IC tag 23 and the mobile terminal device 70 added to the hands-free device. Wireless communication is performed with the non-contact IC tag reader 21 provided in the device, and the identification ID 45a of the non-contact IC tag 23 attached to the hands-free device is the ID of the hands-free device of the genuine product and the conforming standard product. Communication with hands-free devices is permitted only when it is authenticated, and communication with hands-free devices other than genuine products and compatible standard products is prohibited. By prohibiting communication with hands-free devices other than genuine products and conforming standard products, impedance mismatch between the mobile terminal device 70 and the hands-free device, damage to communication data caused by differences in pin arrangement, Damage to the mobile terminal device main body is prevented in advance. Moreover, in this Embodiment, between the non-contact IC tag reader 21 provided in the fitting part with the external connection terminal 90 of the portable terminal device 70 and the non-contact IC tag 23 attached to the hands-free device. A communication method with a communication distance of several centimeters is adopted. As a result, when a hands-free device that is not genuine or compatible standard product is connected to the mobile terminal device 70 and communication is attempted, even if a genuine or compatible hands-free device is placed nearby, Thus, it is possible to prevent erroneous reading of the identification ID 45a without erroneously reading radio waves from the hands-free device.

As described above, in the present embodiment, it is possible to realize the portable terminal device 70 having extremely high reliability and safety.
