PURPOSE:To eliminate the need of the allocation of a terminal address executed by a system supervisor at the time of increase/removal of a terminal by constituting this system so that a terminal system determines an address of the terminal system based on user discriminating information of a recording medium. CONSTITUTION:A host system 10 manages discriminating information 11 for discriminating uniquely a system user, and in a recording medium 51 distributed to the system user, the discriminating information is written in advance. Also, the respective terminals 50 are not provided with a prescribed terminal address and the terminal address is determined well-definedly by inputting the discriminating information. In such a way, the terminal address is not overlapped and the increase/removal of the terminal 50 can be executed freely, and also at the time of utilizing the terminal system, the validity of the user is checked by security information. |
