After the last burglary attempt, I was fed up with our current locking system.  My husband and I would leave for work in the morning, only to return to an empty house, with the remaining household goods in disarray. We had consulted a locksmith on how we could get better locks, but it seemed that the burglars got better. Someone recommended we change our door and install a biometric locking system. I was initially apprehensive about the technology,but it proved to be a worthwhile investment. Know I can enjoy peace of mind whenever I sleep.

How to do biometrics locks work?

A biometric lock uses a persons’ fingerprints to open the lock. Fingerprints are unique,and this prevents unauthorized entry. When you observe your finger, you will notice a set of ridges and valleys. The biometric will scan for unique patterns and if they match with what is on their database access will be permitted or denied. Unlike the key system that requires you to travel with a pair of keys, there is no chance of you forgetting your fingerprints at home.


A fingerprint template of authorized users is created the first time you install a biometric lock. The fingerprint pattern is converted into numerical data. At the heart of the biometric software is the matching algorithm. The biometric system captures minute data from the finger pad from various points. This eliminates chances of error. When your fingerprint matches with what is in the database a green light will be displayed.

While fingerprints are unique, they can easily be collected and used to gain access to a building where biometric locks are used. We leave our fingerprints whenever we hold a cup or bottle or when going to the lavatory. Someone can create a mold of your finger when they have your fingerprints. Some biometric locks have capacitors that check the pulse rate of the finger to ensure that it is a live finger.

If you have been itching to get yourself a biometric system be on the lookout for vendors who have built a reputation and who have been in the industry for long. Find a system that has a backup plan when your fingers are cut. The lock should also be made from high-quality materials like steel or aluminum. Lastly, you should check the biometric system power supply. You do not want to spend the night in the cold because there is a blackout. Their biometric system should have a backup plan like rechargeable batteries.
