Biometric fingerprint door locks have been around for over 30 years, ever since fingerprint recognition software was reliable enough to provide accurate and constant recognition of scanned patterns. At first, these scanners were large and chunky and were used for military and high-security companies. Those locks were used instead of common locks for storage units.
Today, due to the advancement of recognition software and hardware, anyone and everyone can have a biometric fingerprint door lock and door access control system installed. There are many options to choose from, but we will concentrate on two model types, mortise and stand alone.
How a biometric fingerprint scanner works
Like in biometric gun safe, fingerprint scanners are considered today as simple machines to make; they employ a fingerprint scanning glass that you place your finger over to initially record your fingerprint into the database. The software then scans all fingerprints and compares them to the database of fingerprints in store, if the scan matches to a level of integrity accepted by the software, then the door mechanism is activated.
A fingerprint scan is a personal key, and when used will secure access to specific users. However, the scanner is only as good as the locking mechanism, so you must make sure you buy a system that fits into a mortise lock in place or comes as a complete unit. Now, once you buy a complete unit, you have to look at the lock and not just the scanner. Don’t let the fancy buttons, screen and lights take your eyes off the real issue, the lock.
Make sure that the lock is up to standard, made of durable materials and that it will secure your location properly. Also, check to see how the lock is powered, is it by battery or connection to the main power supply. Also, check if the system can be accessed by a security system network, or by wifi, Bluetooth or any other option that can make the system vulnerable, but at the same time more convenient.
Some models come with fingerprint scanning, keypad input, and key lock. Others will include access via a mobile device, a remote control, a smartphone, some keycard and other biometrics. Hybrids can deploy all systems together or only one to activate the system. This means that if you have a triple hybrid system, it will require three levels of activation to open the lock. Other triple hybrids only require one of three to open the lock. So, make sure you understand the levels of confidence and security you are buying.
Remember we talked about the lock, well this is important. Is the locking mechanism a mortise lock? in this case, the lock is inserted into a door pocket; this means that the unit fits into a mortise lock that is in place. Or is it a standalone? A stand-alone means its attached to a door such as a unit attached to a glass door and comes with the actual locking mechanism built in. Also, how secure is the locking mechanism, is it only a lock bolt, or is there a deadbolt?
Elements to Buying
When buying a biometric fingerprint lock, check for the brand and manufacturer. The brand name should be known; it doesn’t need to be a leading name since not all leading brands produce the best fingerprint locks. Check up online reviews and look for the reliability of the design. How many memory allocations it has, which will let you scan in more than one fingerprint. The final piece in the puzzle designs, certainly, you should buy one that looks good and fits in with your environment. Finally, check the price for your budget considerations. You will find that these locks are not as expensive as you think and are a great security device where you want extra privacy.
What did we look for?
To make life easier, we broke down what we wanted from the lock into four main categories:
- Software Capability; how versatile and reliable is the software?
- Hardware Reliability; how reliable and sturdy is the hardware?
- Lock Mechanism; how strong and smooth is the locking mechanism?
- Design; what does it look like (subjective of course)
Our review is based on these four categories, which will make life easier for all of us. With no further ado, let's take a look at the best biometric fingerprint locks you can buy online.
Check out these fingerprint door locks:

5. SAMSUNG SHS-H700 digital door lock keyless touchpad security
- Samsung Fingerprint Digital Door Lock
- Automatic sliding cover and wide touch pad screen
- US version with English Interface and Manual
- Mechanical override key
- 100 Fingerprints and 1 Access Code
Samsung is a name synonymous with excellence. So are their biometric fingerprint locks. There is not much to add when the name is Samsung, so let's go straight into the details.
The Samsung software package that comes with this lock includes a 100 fingerprint database, as well as 100 passcodes per user. This unit provides a double activation security measure, where you need to pass the fingerprint scan and the passcode as well. So, it’s a double security feature that makes this particular model very hard to overcome.
What is nifty is a sound linked digit code, this means you can set sounds to different digits so if you cannot see the keyboard you can at least hear it.
As with all Samsung products, they go through rigorous testing and checking. These locks are all electrical shock proof, circuit instability proof. They also added extra heat prevention where the mechanism can withstand the heat of over 60⁰C, in which case the lock will open automatically.
Now in our opinion, this is a problem, since thieves can use a small blowtorch and the door will be bypassed. What we did like is that is has a manual override when the system becomes unstable or stops.
The locking mechanism comes with a night/day lock on the inside, which is a great future since this secures the room when it is occupied. Another great feature is when the power runs out, there is an inlet that lets you open the door with a 9v battery. The system is used with a standard mortise lock, so you can insert this over any mortise unit you have in place.
Very smart, smooth looking design, which is what you would expect from Samsung.
A reliable model is coming from a reliable company with a lot of customer service

The Ardwolf M400 Security door lock system is a great home system for sophisticated users that want a bit more protection than a standard lock and key unit.

The Ardwolf uses an Optical Sensor and has a touchscreen keypad. The touchscreen is made of durable material that is easy to wipe against remaining fingerprint signs. The fingerprint scanner overlooks residues from previous prints.
The system operates from 4 AA Alkaline of 1.5V and can operate up to 5,000 times before replacement is required. It has a versatile temperature range of -15oC to around 55oC. The processor is an ST chip, which means it gives you fast and efficient processing power.

This is another Samsung digital door lock that comes with proven and reliable features. As a mortise lock unit, it comes with its own mortise locking mechanism, so you will need to take out the old mortise locks and replace them with this one. The system supports RFID, keypad, biometric (fingerprint), or Bluetooth.
The software provides you with any 4 to 12-digit number combination, and you can save up to 10 such passcodes. It is also RF ID ISO 14443A compliant, and you can add up to 20 Samsung key tags or cards. You can enter up to 100 fingerprints into the memory bank. The system requires two methods to operate the lock, a fingerprint and passcode combination.
This is a push-pull mechanism, dual way, which means you push from the outside and pull from the inside, which does not conform to fire regulations, and in my opinion poses a problem. There is no handle, so you cannot force the mortise lock to open without the proper code and authentication.
A very futuristic sleek design aimed.
An expensive item, but it is Samsung, and you do get quality. My only issue is that it poses a fire hazard threat since it pulls from the inside.

Biometric fingerprint locks are abundant on the market. There are pricey high brand models with multiple functions and are incorporated into the IoT. Other are simple locks that provide a biometric solution to a mechanical key.
The further development of IoT will introduce over the next few years comprehensive locking systems that link up to your smartphone and provide real-time metrics and control for ever day use. These systems are already in place in bespoke security systems but are leaking into the market as IoT grows.
The models we provided are low to middle range units, they are easy to install, and maintain and provide extra security to an adequate mechanical system. Just remember, the use of a biometric lock does rely on electricity, so if you do install a stand-alone unit with battery packs, make sure you check their power and replace batteries.
Another issue to remember, a biometric lock is not impregnable, and while it sounds so nifty and scientific, is in fact it’s just another method for operating a lock. Which means, all you are doing is replacing your key, if your lock is not strong the biometric unit will not make it any stronger.
