Last updated: October 1, 2023

KEY TAKEAWAYS

During the mid-19th century industrial revolution, the lock sector experienced exponential growth. James Sergeant also invented the earliest prototype of a digital lock during this time. Back then, it was not equipped with any biometrics authentication software and could only lock and unlock doors at a predetermined time. Fast forward to today, digital locks have evolved into a popular security device known as smart locks. 

A smart lock is designed with the latest identification technology that can provide users with intuitive, complex, and smart identity management systems. On top of that, a number of these devices can easily integrate with your existing security alarm system. Continue reading the article below to find out how a fingerprint door lock system works. 

What Are Fingerprint Door Locks

Fingerprint locks are recognized as biometric door lock systems that scan a person’s fingerprints to determine whether to provide access or not. In order to readily identify someone, this electronic device stores the fingerprints of every authorized person. When that person tries to open the door, the lock will utilize their fingerprint as their personal access key and will unlock if the prints match. 

Most smart lock products are equipped with fingerprint scanners capable of storing several fingerprints of multiple people. This way, you easily provide property access to each user without duplicating keys. 

How Does A Fingerprint Lock System Work

In reality, the fingerprint lock technology operates using a simple method — scan your fingertips, convert it to fingerprint data, and store it as a numerical template. With this, your fingerprint will be saved as a numerical pattern and can be used to unlock the door without entering a numerical code or password.

It only takes a few seconds for the scanner to convert your fingerprint information into a numerical template that it can easily store and use. Once saved, the fingerprint lock system can use your template to grant you access in the future. However, remember that most lock systems can only effectively recognize your print if there is no obstruction between your fingertip and the scanner.

To set up your fingerprint lock, you must firmly place your fingerprint on top of the scanner. Give it enough time to scan your print before removing your finger. Repeat this process to grant security access to other family members or authorized people.   

Should You Get A Fingerprint Lock For Your Door

With its sleek design and advanced biometrics technology, many homes are now equipped with fingerprint door locks. Here are some advantages a fingerprint door lock provides for homeowners:

Cost-Efficient

Biometric security systems are nothing out of the ordinary. Instead of fingerprint scanners, some smart locks are equipped with iris scanners that utilize the iris to authenticate your identity and grant access. Other lock systems are voice automated. However, a fingerprint door lock is relatively cheaper than iris scanners and voice-based locks. At the same time, it incorporates most of the benefits associated with other biometric security systems.

Improved Security Features

A fingerprint door lock system provides unparalleled security and peace of mind. It is significantly more secure than a traditional deadbolt or a numeric keypad lock. Burglars can easily destroy your door handle or hack your electronic passcode to gain access to your property. However, with a fingerprint lock, the only access is through the use of prints that are nearly impossible to replicate or alter.  

Convenience

The fingerprint scanner only requires a few seconds to scan and recognize your print. It is a quicker and more convenient to unlock your front door than with physical keys or numeric codes. On top of that, you won’t have to worry about going to a locksmith to duplicate your key and give other people access. 

Easy Installation

A fingerprint door lock system does not require professional installation as it can easily fit into any door handle. Additionally, numerous design options, like satin nickel and brass, can complement any home’s architectural style. 

Reliable

Physical keys are likely to get misplaced or lost, especially when you travel often. They are also costly and a hassle to replace. On the other hand, each individual has their own set of prints that can’t be misplaced or replaced. Fingerprint authentication also results in fewer misidentifications compared to voice-based locks.

Smart Home Compatibility

Modern fingerprint door lock systems are now smart home compatible via Bluetooth or Wi-Fi. You can now easily manage your door lock system with integrated smartphone apps over your home’s WiFi connection. Others are designed to be compatible with Apple HomeKit, Amazon Alexa, and Google Assistant. With smart home compatibility, you can track who enters or leaves your home from anywhere, giving you complete control over your home’s security.
