How do you open a door handle with your fingerprint?

Fingerprint scanners are being used more and more. They’re on many phones, and now you can even use one to open your front door. A fingerprint is unique; the chance of someone having the same fingerprint as you is 1 in 64 trillion. Even identical twins, who share the same DNA, will have completely different fingerprints.

There are various ways a fingerprint can be read to unlock something. For example, an optical scanner uses light to create a highly accurate image of the fingertip. There’s also the capacitive scanner, which uses electricity instead of light. Both are examples of biometric scanners, which use a physical characteristic of a living being. In a fingerprint door lock, this is your finger, of course, but a biometric scanner can also scan your eye — like Face ID on phones.

Benefits of a fingerprint door lock

A door lock that you can open with your fingerprint offers many advantages. Some are easy to imagine — like not having to carry a key anymore — while others are less obvious. Below, we’ve listed some of the key benefits:

• No forgotten keys: The most common reason people get locked out is because they forget their key. They close the door behind them or lose the key along the way. With a fingerprint door handle, this problem disappears — your key is always with you, attached to your hand.
• High security: Since a fingerprint is unique to you, a fingerprint door lock offers a high level of security. No one can open the door without your finger. Keys can be stolen or copied, but doing so with a fingerprint is much more difficult.
• Multiple users: Most fingerprint door locks allow you to add multiple users. With the Klink Smart One, you can add up to 300 fingerprints to the system. This is ideal for households with many guests or office buildings where you don’t want to constantly open the door for visitors.
