How Does Biometric Door Lock Work

The latest door readers can also use your smartphone to open the door.

How does biometric door lock work.

Basically fingerprint locks operate by scanning and converting your fingerprint data into a numerical template. How biometric fingerprint locks work human fingerprints are unique so a biometric fingerprint lock grants access only to the person with the correct fingerprint. 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.

Some biometric door locks also require you to input a personal key along with your fingerprint as an added confirmation of your identity. The access control readers use credentials which can be cards that fit in your wallet or thick lanyard cards with holes that can be worn around your neck or keyfobs that attach to your keyring. 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. Unlike traditional door locks they do not need a key since your fingerprint is the key to open up the door.

For starters it helps to know how a biometric lock works. 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. This process is then repeated every time you want to grant someone access. Safe access is granted to stored fingerprints and denied to any other unrecognizable prints.

Biometric fingerprint locks have a scanner to scan a fingerprint and allow access to a home. These recognition patterns are then encoded into a set of data points and compared against the existing database. The door readers control the electric lock and determine who enters the building. These types of scanners can be tricked by presenting a photo of the print.

There are the optical scanners and they in essence take photos of your finger and then store the photo for matching. The way fingerprint scanners scan is different actually. There are various ways of taking fingerprint scans. In essence these locks use scanning technology to copy and store fingerprints as computer algorithms in the lock s database.

Biometric door systems work by identifying individual biological recognition patterns such as fingerprints facial recognition and even body motion. In this case the characteristics used are the biological features of the personnel.
