The information processing device connects with an external device by a first connection unit and a second connection unit different from each other. An identification information specific to the information processing device is transmitted from the information processing device to the external device via the first connection unit, and further transmitted from the external device to the information processing device via the second connection unit. The information processing device compares the specific identification information received from the external device with specific identification information for comparison, stored in advance, to determine whether or not the information processing device and the external device are in a simultaneous connection state in which the information processing device and the external device are connected by the first connection unit and the second connection unit. |
