A finger lock for door is a smart security device that allows entry based on biometric fingerprint verification. Instead of using traditional keys, users unlock the door by placing their finger on a scanner. This makes the finger door lock a much safer and more user-friendly option.

Because fingerprints are unique to each person, this technology significantly reduces the risk of unauthorized access. Once configured, it remembers authorized fingerprints and grants instant access when a match is detected.

The process behind a finger lock for door involves both hardware and software:

• Enrollment: The user scans their finger. The finger door lock stores this print as a digital map.

• Verification: When the person wants to enter, the scanner compares the fingerprint to stored data.

• Access: If the match is successful, the lock opens.

TCL integrates high-quality sensors and AI-powered algorithms in its products, ensuring quick and accurate recognition every time.

Each fingerprint is unique, making the finger door lock highly secure. No one can duplicate your finger the way they might steal or copy a key.

Forget about losing your keys or forgetting your code. Your finger is always with you, making access easier and safer.
