<p>PURPOSE:To attain an identification quickly and surely without excessive approaching by receiving an infrared signal of an identification information transmitted from an identification part, and identifying it. CONSTITUTION:An identification information SR is transmitted from the infrared ray emitting element 21 of an identification card 20 of this identification system 10, received at the infrared ray receiving element 32 of an identification device 30, and the card 20 is identified. Further, the information by an infrared light is transmitted from the device 30, received by the card 20, and a processing in accordance with the information is executed. In such constitution to execute the infrared communication, the identification can be executed quickly and surely without excessive approaching compared with optical or magnetic methods.</p> |
