Lock cylinder: A class C lock cylinder is preferred, with a high anti-theft coefficient.
02 lock body
Lock body: The lock body is made of stainless steel, which is safe and reliable.

Functional Part
1. Fingerprint identification
Semiconductors should be selected for fingerprint recognition, false fingerprints are rejected, and the safety index is high. Secondly, look at the recognition time, the recognition rate of dry and wet fingers, it is acceptable to recognize fingerprints within 1.5 seconds and don’t consider it beyond that. Fingers are dry in winter, and the recognition rate is also high. Wet fingers are more sweaty than fingers that have been completely soaked in water. Can not buy optical fingerprint recognition.
2. Password
False password function. For example, if the password is set to 6 digits, the password is 654321. When you enter the string of numbers 18946326+654321+86986, the door can also be opened, as long as the continuous and complete real password is included to unlock it. You can enter the beginning and end passwords at will. Even if there are people around you when entering the password, it is difficult to remember the password to avoid embarrassment and password disclosure.
3. Swipe card
For those who have missing fingerprints and are difficult to identify, they can directly swipe the card to unlock it. The card should choose an encrypted anti-copy card. The encrypted card will not be copied by the NFC of the mobile phone, which is safe and reliable. If the card is lost, just delete the lost card directly.
4. Key and power supply port
To prevent the fingerprint lock from being reminded of low battery, if you still forget to change the battery, you can use the key to unlock it in an emergency. There must be an emergency power supply. In case the battery of the fingerprint lock is out of power, it can also be temporarily charged with a power bank.
