PROBLEM TO BE SOLVED: To detect substitution of an integrated circuit even when a device for game and a server are incommunicable.SOLUTION: A collation system includes a management device, a first device for game, and a second device for game communicating with the first device for game and the management device. The first device for game includes an integrated circuit, and the integrated circuit stores own identification information. The second device for game includes control means capable of communicating with the integrated circuit and the management device, and the management device stores the identification information of the integrated circuit as collation information for collation. When the management device and the control means are communicable, the control means acquires the identification information from the integrated circuit to store it and transmits it to the management device, and the management device collates the identification information transmitted therefrom with the prestored collation information. When the management device and the control means are incommunicable, the control means acquires the identification information from the integrated circuit and collates it with identification information stored in first processing. |
