Problems solved by technology
[0002] With the advancement of science and technology, identification devices are used more and more widely. Existing identification devices are generally carried out through electronic equipment, such as: identification through RFID (radio frequency identification technology), and the identified end often needs Provide identifiable information through electronic equipment; but if the identified terminal is set in an outdoor environment, such as: a base station, etc.; it needs to provide power for the identified terminal, which is extremely inconvenient to use, and the protection requirements of electronic equipment are relatively high. Set additional waterproof, lightning protection, and fire protection equipment, which greatly increases the cost of use

The invention relates to the photomagnetic information technology field, to be specific, relates to a photomagnetic information coding disc and an information reading device thereof. The photomagnetic information coding disc comprises a circular disc body, the surface of which is provided with an annular information storage area; the information storage area is constituted by more than two color lumps having different colors; the color lumps are used to form identifiable information after being arranged sequentially; the information storage area is provided with a magnet in an embedded manner. The photomagnetic information coding disc does not require a power supply, and does not require a waterproof device, a lightning protection device, and a fireproof device, and therefore use costs are greatly reduced, and popularization in a market is facilitated.
