As a high-tech product, the Fingerprint Scanner mainly relies on electronic technology and biometric technology. The simpler the environment in which these technologies operate, the better they will perform. On the contrary, the more auxiliary functions there are, the less stable the main functions will be. Therefore, when choosing a Fingerprint Scanner, we only need to choose these functions. Today, the editor of the Fingerprint Scanner manufacturer will explain in detail which functions a Fingerprint Scanner only needs to have. Ang sulud mao ang mga musunud:

1. Turn on fingerprint
Fingerprint Scanner, as the name suggests, the most basic function is to open the fingerprint. Currently, Fingerprint Scanner on the market are generally opened through semiconductor fingerprint heads. The semiconductor Fingerprint Recognition Time Attendance module only recognizes live fingerprints, which is very safe.
Semiconductor fingerprint heads can penetrate the skin and hair layers, so the silicone simulated fingerprints circulating on the Internet are basically useless. The advantage of identifying living fingerprints is that fingerprints cannot be copied or copied. The semiconductor Fingerprint Recognition Time Attendance module has high sensitivity and recognition accuracy.
The semiconductor Fingerprint Recognition Time Attendance module is composed of tens of thousands of capacitors. It forms fingerprint data by collecting the distance from the fingerprint ridges and valleys to the contact plate. Compared with optical scanning, the semiconductor Fingerprint Recognition Time Attendance module can collect fingerprint details more accurately and speed up the collection. .
The semiconductor Fingerprint Recognition Time Attendance module has a high recognition rate. The normal use of the optical fingerprint head will be affected by dry fingerprints and wet fingerprints, causing recognition errors and making it impossible to identify fingerprints. Semiconductors can avoid these problems to the greatest extent.
In addition, semiconductors also have the advantages of low power consumption and small size, which are of great help in reducing the power consumption of Fingerprint Scanner and reducing the size of locks.
2. Information management function
The main function of information management is: users can add, modify and delete user information at will. User information mainly includes fingerprint information, usage information, etc. When a user uses one of these functions, other functions are not affected. If you can use fingerprint + password at the same time, or password + swipe card, you can better guarantee the double password.
This function can effectively improve the convenience of the Fingerprint Scanner. For example, when a relative needs to stay for a few days, as long as the relative's fingerprint is entered, the relative can freely open the door and enter and exit freely without having to configure a key for the relative. After the relative leaves, the door cannot be opened as long as the fingerprint information is deleted. If a nanny or confinement nanny is hired at home, the fingerprints of the nanny or confinement nanny will be deleted after resigning, so there is no need to worry about the nanny stealing the keys.
3. Key to open
Many consumers will think that there are many keys that can open many functions, and using a Fingerprint Scanner is for convenience. If you add a key opening function, what is the difference between it and an ordinary lock? Is the safety performance guaranteed? In fact, this is a national regulation for security reasons-smart Fingerprint Scanner must have a key opening function before they can leave the factory.
After all, Fingerprint Scanner are electronic products, and electronic products will travel or run out of power. To prevent fires or other disasters from destroying electronic circuits, the state mandates that Fingerprint Scanner be equipped with key-open functions.
4. Dummy password function
The dummy password function allows you to enter any number before and after the correct password to open the door when using the password, which can effectively prevent the password from being peeped.
5. Anti-pry alarm function
When damaged by external violence, an alarm will automatically sound to alert neighbors. I don't think any thief would continue to pick the lock when the alarm sounds continuously.
