An IC card provided with a contact-type interface and a non-contact-type interface as the communication interface, and other electronic devices. The IC card identifies the kind of communication data communicated with an external device such as reader-writer, and decides on a communication interface that follows the identified communication data. Then, it is judged whether to switch the communication interface used communication for with the external device between the contact-type interface and the non-contact-type interface. And if it is decided to switch, the communication interface used for communication with the external device is switched.
