PROBLEM TO BE SOLVED: To eliminate the anxiety of a game hall side about the use of a portable communication terminal by a user and to prevent a fraudulent action using a false portable communication terminal in a game machine capable of providing various kinds of information and services by using the portable communication terminal. SOLUTION: The game machine is provided with a communication means for connecting a portable telephone (HP) communicably by a cable and a discrimination means for discriminating the authenticity of the portable telephone. The discrimination means discriminates the authenticity by receiving authentication data for which the model code is ciphered from the portable telephone while the portable telephone is connected and deciphering them, and in the case of a proper connection, reports that effect by making lamps (104) flicker or the like. Thus, whether or not the use of the portable telephone by a player is proper is easily identified and the anxiety of the game hall side is eliminated. COPYRIGHT: (C)2006,JPO&NCIPI
