How Does Biometric Safe Works?

As the crime rate rises, the security situation gets worse day by day. If you want an advanced type of security as the last defense against burglars and thieves, then a biometric safe is the best choice.

A biometric safe at home will offer you the most advanced security. It will also prevent disastrous consequences of having the most valuable thing at home getting stolen.

So, how does biometric safe works? We’ll discuss all of it and its advantages in this article.


What Is a Biometric Safe?

Technology has come a long way in recent years. It wasn’t long ago that biometric safes were only seen in sci-fi movies. Democratization of hi-tech products is making everyone enjoy its benefits to the fullest.

One of the wonders of technology is the biometric system. It helps keep valuables locked down through a variety of security measures. Usually, a home biometric safe comes in a high-grade durable metal casing with advanced locks. Their weight is also exaggerated for difficult mobility.

Biometric is actually a technical term to measure the physical characteristics of an individual. These characteristics fall under the category of face, eye, fingerprint and voice recognition, etc. Retina recognition is the most advanced among all these.

However, the most common biometric recognition pattern used nowadays is fingerprint. It has become so common that almost all modern-day mobile handsets come with one to unlock the phone and keep its information secure. So if you hear the term biometric safe, it will most probably be fingerprint safe.

How Does a Biometric Fingerprint Safe Work?

One of the remarkable features of humans is the unique fingerprint of an individual. Every human being has a unique fingerprint. A biometric fingerprint technology utilizes this singularity to provide security measures to anything.

The biometric fingerprint system has three components:


It scans the individual’s fingerprint and takes a detailed image in an encrypted digital format.


The biometric safe has a mini-computer inside that uses the information provided by the sensor and stores them.


It is basically whatever that connects the computer to the sensor. It helps identify and cross-match the new fingerprint with the old one.

Simply put, the sensor in the biometric safe will scan your fingerprint the first time and store it for future use. You then save that fingerprint as the sole authority of the safe.

The next time you want to open the safe, this scanner will read your fingerprint and crosscheck with the one stored before granting you authorized access to the lock in a second.

It should be noted that the biometric safe do not actually keep a conventional photograph of your finger. For the system to be effective, it needs to create a high-quality template of your fingerprints.

Sometimes the Biometric Safe system requires not one but two fingerprints so that in the event of any problem matching one finger the other can be used for reliable recognition.

Advantages of biometric Fingerprint Safe

Biometric safes are especially popular in the country now as gun safes. There are many advantages of keeping valuables in a biometric safe. Here’s a rundown of some of them:

Don’t Have to Remember the Combinations

One problem about password or combination-protected safes is that you have to remember them all the time. Especially in emergencies, people tend to forget the easiest of things. Many people complained about forgetting the combination exactly in those situations.

With a biometric fingerprint safe, you don’t have this worry anymore. All you need for the safe to open is your fingers. The only thing you need to do is simply place the fingertip on the scanner, and the safe will unlock in a second.

No Key to Lose

Another problem with safes having keys and locks is that you need to keep the key always to yourself so that it doesn’t get stolen or lost. Losing a traditional safe key is a great security risk. Besides, it is also expensive to open the safe without the original key.

With a biometric lock, you don’t have to worry about losing the key. The key to your lock is your own fingers. And nobody can make a fake copy of this unique key. You can be sure at any time or at any place only you have the sole access to the safe.

Fast Access

With a biometric safe, you can get faster access without needing to remember the combination or finding the key. In case of emergencies, these things make life difficult and take too long to open the safe.

This is especially true if it is gun safe. You don’t want to lose even a single moment in unforeseen circumstances needing a gun. The best biometric rifle safe will give you super-fast access to the safe right away.

More Secure

These biometric safes are usually more secure than any other safes since no one can steal the key or get a peek at the combination. You have the advantage of being the only person with authority to open the safe and no one else.

Disadvantages of Biometric Safes

No product can provide an absolute advantage to you. So as you might expect there are a few drawbacks of this technology as well.

Needs continuous power

It might cause a bit of a problem since the safe won’t scan your fingerprint without power and won’t open. Most biometric safes are battery-powered. So if you change them regularly when they get worn out, there shouldn’t be much problem.


Although the price has fallen a lot in recent years, still a biometric safe is much more expensive than regular combination or lock safes. However, considering the safety and security it provides, the money is worth it.

Final Words

With the world getting more lawless every passing day, keeping your valuables safer has become more necessary than ever before. The best way to keep them safe at home is by getting a biometric safe.

Knowing how a biometric safe works will put your mind at ease regarding the safety of your possession.
