How Fingerprint Door Lock Works?

Security has always been very important to people. In the past, we protected our valuable items by keeping them in secure places like dungeons. Now, we use advanced technology to protect our data with layers of security software.

Modern security involves using a variety of technologies, such as web-based security services, biometrics which uses distinctive physical characteristics to identify a person and personal gadgets that have security measures installed. The application of biometrics is one significant development in security technologies. As one of the first and most widely used biometric security systems, fingerprint door locks will be the subject of our discussion in this guide. 

What are Fingerprint Door Locks?

A fingerprint door lock uses electronic technology to grant access. It's a smart lock that doesn't require a key or magnetic card to enter a locked area. Instead, you gain access by scanning your registered fingerprint.

You may be wondering why a fingerprint door lock is preferable over traditional keys or other options. In addition to being dependable and simple to operate, fingerprint locks also remove the possibility of losing or forgetting your keys. These locks offer exceptional security since each person's fingerprints are distinct. Furthermore, you cannot simply forget or guess your fingerprints, unlike passwords. Thus, best fingerprint door locks provide a practical and safe method of keeping your house or place of business safe.

How Do Door Fingerprint Locks Operate?

Let's talk about how fingerprint locks actually work. These door locks with fingerprint readers scan and convert your fingerprint into a numerical template. This is how it works! Your fingerprint is transformed into numerical data and saved as a template the first time you touch your finger on the scanner. Each time an individual intends to gain entry, they place their finger on the scanner. The scanner then checks this fingerprint against the saved template. If it's a match, the door opens. If not, the door stays locked. Simple, right?

The key part of this process is matching the fingerprint using a method called Minutia matching. This involves finding specific points on your fingerprint, like ridges and their direction, and storing this information. When someone tries to unlock the door, the scanner compares their fingerprint to the stored template. If they match, a green light shows, and the door opens - usually in less than a second. Using advanced security like thumb scan door locks can be smart, especially for small businesses moving to new locations. These systems boost security, making employees and customers feel safe. Plus, you never have to worry about lost keys or forgotten codes, making fingerprint smart locks a great choice for business security upgrades.

How Safe are Fingerprint Door Locks?

Fingerprint locks are typically safe as it is more difficult to imitate someone's fingerprint than to copy a physical lock key. Unlike keys, you cannot lose your fingerprint. Biometric locks are more secure and convenient to operate than traditional locks. However, no lock can be completely secure. If someone attempts to force open a door, whether it has a biometric or traditional lock makes no difference.

What should I check for in door locks with fingerprints?

When choosing a fingerprint door lock, consider these tips:

  • Look for a backup option

  • Ensure the lock has a keypad or mechanical key slot. This way, if the fingerprint scanner fails (due to a cut or power outage), you still have a way to access your home.

  • Check the False Rejection Rate (FRR)

  • Avoid locks with a high FRR, as this could lead to more frequent failures in recognizing your fingerprint.

  • Opt for sturdy materials

  • Choose locks made of tough brass or steel over aluminum. These materials are harder to break with tools like a crowbar and provide better support for the thumb print locks system.

  • Consider power source

  • Check how the lock is powered. Some locks use batteries while the others can be connected to your home's main power supply. Select the option that suits your needs best.

  • Capacity for fingerprints

  • Look into how many fingerprints the system can store. This determines how many people can have access at once, which is important for securing offices or areas with multiple users needing access.


    Use Tips

    When you first touch your finger to the reader, it will save your fingerprint image. Repeat this each time you want someone to have access to your home. If the system recognizes the fingerprint, the door will unlock. If not, the person won't get in. Some readers also check heart rate and body heat to prevent misuse, making them more reliable.

    Sometimes, the reader might not recognize your fingerprint right away. If this happens, try these steps:

    • Keep your finger on the reader a little longer.
    • If you used hand cream, wipe and dry your hands.
    • Finger injuries can affect recognition, so save the fingerprints of several fingers from both hands.

    Bottom Line!

    Fingerprint smart locks work wonderfully. They're cost-effective, easy to use, and safe. All you need is your fingerprint; a key or password won't work. Many others can have access, and you can take it down at any time. Installing a fingerprint door lock is something you should think about for your business or residence. It will probably turn out to be a wise security investment.
