Should I Buy a Fingerprint Door Lock?

Advanced Fingerprint Identification

Fingerprint recognition is a fairly new technology. It is now being used to access all sorts of things, the most obvious of which is our smartphones. Unlike a number code, your fingerprint is unique and difficult to mimic.

Moreover, every person is born with a different set of fingerprints. This makes fingerprints a good and reliable biometric identification method.

Easy Installation

These smart locks come with a lot of advanced features, starting with fingerprint scans to sensors that detect intrusion. But the ease of using these smart locks is what’s important too.

Most smart locks only require a screwdriver for installation. Also, they do not require hard wiring, which makes them super easy to mount.

Access for Multiple Users

If you have a physical lock at home, you will have to make multiple copies of the key to give every member of your family access. If you forget to carry your key one day to the office, you will have to wait for your wife to arrive back from work. 

But with these smart locks, you do not need a physical key. Moreover, you can grant access to anyone in your family. Most of these smart locks have storage for 100+ fingerprint profiles.

Remote Access

If your friend or a distant relative is visiting your town for a few days, you can give them access to your home using the mobile app that most of these smart locks come with.

Common Features to Consider

Access Mechanisms

And secondly, they come with digital keypads. For preventing peeking, these keypads can jumble the position of the digits randomly.

High Security Grades + Encryption

Moreover, to ensure they can prevent theft, they also are tested for intrusion. If you are getting a smart lock with Wi-Fi compatibility, try and go for one with standard encryption protocols.

Battery Powered

When buying a smart lock, try to get one with backup batteries. This way, you will be able to retain all your user data during a power outage.


Geo-Fencing refers to the technology of creating an electronic fence around a certain boundary. This technology is used to make smart locks aware of the location. As geo-fencing educates smart locks about the structure of your home, it can trigger an alarm when it detects any anomaly too.
