Why Should you Consider Getting Fingerprint Door Locks?
In the event that you have a guest, housekeeper, and a door walker, you don’t need to make copies for each one of them. Simply share the code. Monitoring who enters your house and at what time also becomes easy. Nevertheless, one question remains. Out of all the possible methods, why should you consider getting fingerprint door locks?
That’s because it is quite secure. Remember that fingerprints are unique. Not even identical twins have similar fingerprints. In addition to being distinct, fingerprints are not easy to forge either. Some systems allow you to store up to 10 fingerprints, given the high chances of having more than one person in need of accessing the room or building.
As for the fobs, they are not that different from keys because you have to carry the card. On the other hand, wireless smart locks need to come as part of a smart home package, which is not cheap, because they lack a dedicated mobile app to control them.

How Does Fingerprint Door Lock Work?
The concept of how a fingerprint door lock works are quite simple. It is all about scanning the fingerprint data and converting it into a numerical value. Upon buying a fingerprint door lock, you will have to place your finger on its scanner. Since it is the first time, scanning takes place, and the equivalent numeric value is stored in the device’s memory. That should be done for all the people that you want to grant access to.
Once their fingerprints are stored, this is what happens when they try to access the entrance. Upon placing the finger on the scanner, its numeric value is recorded. However, instead of being stored, it is compared with the already saved values. If there is a match, access is granted immediately. On the other hand, if there is no match, the door won’t open. To achieve that, most fingerprint door locks use the Minutia matching algorithm.
It works by recording several minutia points on your finger during the first registration. Usually, they also take into account the positions as well as the directions of the minutia points. Most fingerprint door locks will show green and red LED lights when access is accepted and denied, respectively.
