A new generation of fingerprint technology leader

Fingerprint lock is a kind of intelligent lock with human fingerprint as identification carrier and means. It is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. Fingerprint lock is generally composed of electronic identification and control, mechanical linkage system. The * * and non replicability of fingerprint decide that fingerprint lock is a more secure lock among all locks at present. In addition to fingerprint identification, the fingerprint lock shall be equipped with an emergency mechanical key in accordance with state regulations. The product quality specification is mainly based on the public security industry standard of the people's Republic of China < General technical conditions of fingerprint anti-theft lock.

Fingerprint lock The new generation fingerprint technology leader

fingerprint refers to the uneven lines on the front skin at the end of the finger. Although the fingerprint is only a small part of the human skin, it contains a lot of information. These lines are different in patterns, breakpoints and intersections. In information processing, they are called "characteristic medicine has proved that these characteristics are Different, and these features are * * and permanent, so we can match a person with his fingerprint. By comparing his fingerprint features and pre saved fingerprint features, we can verify his real identity. Therefore, the above characteristics of fingerprint become more important evidence for identification and are widely used in public security criminal investigation and judicial fields. Fingerprint authentication is convenient, fast and accurate.

According to the anti-theft performance, the current popular fingerprint lock is divided into two types: ordinary fingerprint lock and fingerprint anti-theft lock. The common fingerprint lock is not much different from the original electronic lock, mainly using fingerprint authentication, butIt is not applicable to the existing domestic anti-theft door. This type of fingerprint lock does not have the hook of heaven and earth bar, and cannot use the anti-theft door heaven and earth security system (all the imported fingerprint locks do not meet the national industry standards, and can only be used for wooden doors). The other is fingerprint anti-theft lock, which has better security. It can be applied to standard anti-theft door, and can automatically or semi-automatically connect the anti-theft door with Tiandi lock system, without affecting the performance of the original anti-theft door.

According to the classification of identification carrier, fingerprint lock can be divided into two types: optical fingerprint lock and semiconductor fingerprint lock. The optical system is relatively stable and adaptable, which is mostly used in anti-theft locks; the volume of semiconductor is relatively small, and the recognition range is wider than that of optical system, especially for dry fingerprint users. However, the semiconductor fingerprint lock has higher requirements on the use environment, which is easy to scratch and scrap. Generally, it is used in places (such as banks) and products (such as mobile phones and laptops) under the supervision of special personnel. There are advantages and disadvantages of the two materials. Generally speaking, they are: optics are afraid of dryness and semiconductors are afraid of wetness.

At present, in the market, in addition to fingerprint identification, some of them are also equipped with password function, so this kind of fingerprint lock is often called fingerprint password lock. Fingerprint, password and emergency key can be opened separately. The password function depends on the security settings. The length of the password is between 4-12 digits. The number keys are generally 0-9 full digital input mode.

In addition to the door opening function, the fingerprint lock generally has the function of adding, deleting or clearing the fingerprint. The high-performance fingerprint lock is also equipped with a man-machine dialogue system such as LCD, which has a high level of intelligence and is relatively convenient to operate and can provide operation guidance, query and use records andSet parameters, set status and other functions. Fingerprint management generally implements hierarchical management. The administrator has all functions such as opening the door, adding fingerprint, deleting fingerprint, clearing fingerprint, querying usage record, setting system parameters, while the ordinary user only has the function of opening the door.

The power supply mode of fingerprint lock generally adopts 4 No. 5 alkaline batteries, which can be used for about one year (depending on the function, power consumption design, use times, etc.). The anti-theft fingerprint lock produced according to the industry standard shall be equipped with an additional emergency power supply interface, which can be externally powered by 9V laminated battery. Both batteries are available in supermarkets.
