PROBLEM TO BE SOLVED: To specify the terminal as a communication opponent only by reading a code pattern displayed currently on one of terminals under a condition, in which self communication identification information is indicated as a code pattern for each communication opponent. SOLUTION: Each slave terminal 1 serves as a selective object as a communication opponent, generates bar code information as a display by converting self communication identification, and information to the bar code information. A master terminal 1 as a transmitting originator read out the bar code information displayed on any of the slave terminal 1 as a selective object for the communication opponent, decoding the bar code information to communication identification information, and specifies the communication opponent based on the communication identification information.
