What is a Biometric Reader
A Biometric Reader is a device installed on doors and is use to detect a body part such as your fingerprint, retina, facials, etc. in order to gain access to a room. For example, your fingerprint is scanned by sensors that identifies the unique mapping of your fingerprint and compares it to a fingerprint of you stored on the database. Once your fingerprint is scanned an authenticated with a matching print, the door will be unlocked.
The benefit to this is that you don't have to carry a key and worry that it will can get lost, you don't have to carry a key card, or have to remember a sequence of numbers, becasuse everything you need to open the doors to a biometic reader is right at your fingertip.
Biometric Readers are great for Residential and Commercial use.
