How Does Biometric Door Lock Work

Biometrics can use physical characteristics like your face fingerprints irises or veins or behavioral characteristics like your voice handwriting or typing rhythm.

How does biometric door lock work. 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. Biometric fingerprint locks have a scanner to scan a fingerprint and allow access to a home. Basically fingerprint locks operate by scanning and converting your fingerprint data into a numerical template.

The way fingerprint scanners scan is different actually. Safe access is granted to stored fingerprints and denied to any other unrecognizable prints. There are the optical scanners and they in essence take photos of your finger and then store the photo for matching. 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 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. 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. This process is then repeated every time you want to grant someone access. The door readers control the electric lock and determine who enters the building.

Based on this biometric locks can recognize and separate different users. These types of scanners can be tricked by presenting a photo of the print. In essence these locks use scanning technology to copy and store fingerprints as computer algorithms in the lock s database. There are various ways of taking fingerprint scans.

Some biometric door locks also require you to input a personal key along with your fingerprint as an added confirmation of your identity. 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 latest door readers can also use your smartphone to open the door. For starters it helps to know how a biometric lock works.

These recognition patterns are then encoded into a set of data points and compared against the existing database. They use readings unique to each individual like fingerprints or retina scans when granting access.
