What a good Fingerprint Scanner must have

Lock is a well-known furniture item, and everyone must know its function, which is safety and prevention. So for Fingerprint Scanner, I don`t know if you have an in-depth understanding of them. Next, I will tell you the standards for inspecting Fingerprint Scanner:

1. Voice operation prompts simplify operation
The voice operation prompt means that each link has a human voice to prompt the operation, which simplifies the operation and allows people who do not understand the operation to follow the prompts to complete the operation step by step. I think this function is very useful for the elderly and children.
2. Double protection of fingerprint verification and key
The state stipulates that Fingerprint Scanner must have a key-opening function before they can leave the factory, mainly for security reasons. Fingerprint Scanner are electronic products after all. Electronic products may go on business trips or run out of power. In order to prevent fires or other disasters from damaging electronic circuits and putting people in danger, the state mandates that Fingerprint Scanner must be equipped with a key opening function. . A Fingerprint Scanner without a key-to-open feature is a dud.
3. Optical collection is more widely used than semiconductor collection
It is understood that fingerprint unlocking on the market now generally uses optical fingerprint collection, and a few use semiconductor collection. Semiconductor collection technology is rarely used in the field of Fingerprint Scanner because it is easily affected by static electricity, sweat, dirt, finger wear, etc., has insufficient stability, is not resistant to wear, and has a short lifespan. Since optical collection can collect from multiple angles and in all directions, it can achieve good accuracy, clear fingerprint graphics, stable recognition, and effectively improve the instability of semiconductor collection. Therefore, it is widely used in Fingerprint Scanner.
4. The anti-pry alarm function is effective for home security.
The anti-pry alarm function can be said to be one of the Fingerprint Scanner functions that is effective in improving home security. When the Fingerprint Scanner is damaged by external violence, an alarm will automatically sound to remind community security. Better ones can even automatically send warning messages to the owner's mobile phone, or directly contact the police station to automatically call the police to prevent thieves from breaking into the house.
