<p>After electrical connection of a predetermined contact part is confirmed, information for identifying the communication party is generated before radio communication, and the information for identifying the communication party is exchanged between communication devices through the predetermined contact part. The problems, e. g., of security of when the communication devices conduct one-to-one radio communication are solved, the communication party is reliably identified, and an increase in cost is suppressed.</p> |
