Digital Fingerprint Locks & Biometric Door Locks

Frequently Asked Questions

1. What is a fingerprint smart lock?

A fingerprint digital lock is an advanced type of lock that uses fingerprint scanning technology to unlock doors via fingerprint recognition, offering a keyless entry solution. This enhances security and convenience by allowing authorized individuals access with just a touch of their finger. So instead of using a passcode or physical key to unlock the door, the WELOCK Finger Print Digital Door Lock can store up to 100 fingerprints and allow you to manage access remotely through your smartphone (WELOCK WIFIBOX3 is needed), and you can place your thumb-scan door lock to unlock the door.

2. How do fingerprint locks work?

Fingerprint scan door locks operate by scanning and converting your fingerprint data into a numerical template.

The first time you place your finger on the scanner, the fingerprint template is saved and the data is converted to numbers. This process is then repeated every time you want to grant someone access. The next time someone places his/her finger on the sensor, it matches the data obtained through the finger with the pre-saved values. If a match is found, access is granted, and the door opens. On the other hand, if someone else is trying to get through, access is not allowed and the door remains locked. Easy enough, no?
