Are fingerprint door locks safe?

When it comes to fingerprint door locks, safety is always a top priority. Many people value the aesthetics and security value of the space where the lock is installed. Here are the outstanding features of this type of smart lock.

Fingerprint door lock is safe thanks to high security features

Modern fingerprint door lock versions are capable of recognizing fingerprints with absolute accuracy. In biometrics, each person's fingerprints are unique, and no two people's fingerprints are ever identical. Therefore, when using a fingerprint door lock, you will not have to worry about duplicate or fake fingerprints. In addition, only the installed fingerprint can open the door.

Some high-end fingerprint locks are also equipped with an alarm feature when an intruder breaks in. In this case, the owner can detect dangerous situations and handle them promptly to ensure safety.

Smart automatic door lock

Currently on the market, there are many fingerprint door locks equipped with smart automatic door locking feature. Accordingly, the lock will automatically close the latch after a few seconds from closing the door. If you install this automatic feature, your home will be safer and avoid the case of strangers breaking in due to forgetting to lock the door.

In addition, today's smart fingerprint door lock models not only use fingerprints to open the door but can also be combined with many other forms. Some other security methods that can be combined with fingerprint unlocking are magnetic cards and passwords.

Control activities in and out of the house

When installing and using fingerprint door locks, users have the right to control activities in and out of the house. In fact, fingerprint locks are like electronic devices. They can allow you to record the date, time, people entering and leaving the house... Moreover, you can decide who can open the door by setting up fingerprints, or through your smartphone to set the feature to open the door to the house within a certain period of time.

This type of lock is especially convenient for parents who want to monitor their children's activity schedules.

Solve the worry of forgetting or losing keys

Using a fingerprint door lock will be very convenient for those who are forgetful or often lose their keys. You can save time and effort because you don't have to carry around keys like with traditional door locks.

How fingerprint door locks work

Fingerprint door locks work by scanning fingerprint data and converting it into a digital template. The fingerprint template is saved when the user places their finger on the reader and performs a fingerprint scan to unlock the lock. Access to the device is granted if a match is found with the stored information and the door is opened. This process is repeated every time you want to grant access to the lock to someone.

The fingerprint lock is quite simple to use. You just need to activate the fingerprint scanner, then place your hand on the scanner screen and you will open the door.

Although there are many outstanding features, fingerprint door locks also have certain limitations. You need to remember that not all types of doors can be installed with fingerprint locks. Before deciding to use them, you need to measure the appropriate door thickness.

Moreover, you should also pay attention to choosing genuine, quality fingerprint locks to avoid buying fake, unsafe products.
