PROBLEM TO BE SOLVED: To provide a discrimination system at a low cost appropriate to discriminate a relatively small number of kind. SOLUTION: This discrimination tag is provided with a first and a second resistors 2 and 3 provided on a insulating board 1, and a setting means 7 for setting the resistance value between a second and a third conductive patterns 5 and 6 at the predetermined value. Voltage is applied between a first and the second conductive patterns 4 and 5 to discriminate the voltage detected from a third conductive pattern 6. With this structure, a discriminating device 10 for discriminating the discrimination tag can be formed of electric circuit parts without requiring optical parts, and manufactured at a lower cost in comparison with a conventional optical reading device to provide a discrimination system at a low cost. |
