How Does Biometric Door Lock Work

How biometric fingerprint locks work human fingerprints are unique so a biometric fingerprint lock grants access only to the person with the correct fingerprint.

How does biometric door lock work.

In essence these locks use scanning technology to copy and store fingerprints as computer algorithms in the lock s database. Some biometric door locks also require you to input a personal key along with your fingerprint as an added confirmation of your identity. Biometric door systems work by identifying individual biological recognition patterns such as fingerprints facial recognition and even body motion. There are various ways of taking fingerprint scans.

They use readings unique to each individual like fingerprints or retina scans when granting access. Based on this biometric locks can recognize and separate different users. Biometric fingerprint locks have a scanner to scan a fingerprint and allow access to a home. Biometric locks long the stuff of sci fi movies and high security commercial use biometric locks are now making a foray into the world of ordinary business and home security use as well.

How it works like most electronic access control systems in singapore the biometric door access system uses a programmed template and a set of characteristics to limit the entry to an area. These types of scanners can be tricked by presenting a photo of the print. For starters it helps to know how a biometric lock works. Safe access is granted to stored fingerprints and denied to any other unrecognizable prints.

Biometrics can use physical characteristics like your face fingerprints irises or veins or behavioral characteristics like your voice handwriting or typing rhythm. Once you place your finger onto the scanner for the first time the conversion into numerical data takes place and the fingerprint template is saved. Instead of using something you have like a key or something you know like a password biometrics uses who you are to identify you. The way fingerprint scanners scan is different actually.

The door readers control the electric lock and determine who enters the building. The latest door readers can also use your smartphone to open the door. This process is then repeated every time you want to grant someone access. These recognition patterns are then encoded into a set of data points and compared against the existing database.

Unlike traditional door locks they do not need a key since your fingerprint is the key to open up the door. In this case the characteristics used are the biological features of the personnel.
