What about the fingerprint lock now? Is it safe? Will you lock the door and never recognize your fingerprints again?

Although the fingerprint lock is essentially a mechanical lock, the motor is not only controlled by a simple built-in electronic program. After receiving the instruction, the motor will rotate and then open the mechanical lock. No lock is 100% anti-theft, as long as it is a lock, it can be opened, even in the bank vault! But there are still some criteria to judge a good lock, such as the most important lock core grade: the door of university dormitory is generally Grade A-if you lose it and don't want to take the key to the door, you can open the door directly with a meal card. Security doors are generally required to be class B or higher class C. It is said that the key of class C is lost and can't be matched, so we can only replace the lock cylinder and all the keys.

Smart locks sold in China must be equipped with mechanical keys, so the most important standard of smart locks is whether the lock core reaches Grade C or above. There are other criteria: Is fingerprint identification fast? Whether closing the door can automatically lock the door and so on.

Ordinary schools or factory dormitories generally use wooden doors, the most basic locks. Those door locks are generally class a. If you lose it and don't want to spend 5 yuan to get a key at the door, you can open the door directly with plastic sheets such as meal cards, bus cards and bank cards. Security doors are generally required to be above Grade B, especially the lock core of fingerprint security lock in Liu Fu has adopted the highest Grade C certification at present. Once the key is lost, it can't be copied in the market, so we can only replace the lock cylinder and all the keys.

Let's talk about the stability of the fingerprint identification module. First of all, both the optical version and the semiconductor version have high recognition and quick response. Liu Fu's products support biometric identification (in short, it is impossible to open the door by copying the finger module with plasticine, which is very common in foreign movies). Relatively speaking, if the finger temperature of the optical version is too low in winter, you need to put your finger in your mouth to open the door, so the consideration of semiconductors is not so obvious. Liu Fu's fingerprint identification module has a learning function, and the more it is used, the more accurate it is. Take ten thousand steps back. If one day you accidentally cut your finger fingerprint here, Liu Fu fingerprint anti-theft lock can also be opened with password, credit card and emergency key. The online version can also be opened through APP and bluetooth.

If you don't go home for a year or two, should you wait for the manufacturer to turn on the technology in case the fingerprint is locked? Don't bother, take out a modern low-headed charging treasure and connect it to open the door normally. Moreover, the battery of the fingerprint lock is only below 20%, and there is a low battery reminder every time you open the door.

Liu Fu fingerprint anti-theft lock is 9 times safer than most smart locks on the market. As for the introduction of safety, such as automatic door lock, outdoor cat's eye opening, indoor one-step door opening, etc., you can move to Liu Fu official website or online and offline stores for detailed consultation. I won't go into details here. I hope it can be adopted. Thank you!
