What is Biometric System
Biometrics is a branch of science, it is called biometrics, this word is made up of two Greek words bios and metron, in which bios means related to life and matros means to measure, in this technique to identify a person. For this, his biological data like thumb and fingerprints and voice and retina of eyes, impressions of nerves, etc. are used.

Why Biometrics is Necessary
Biometrics is necessary to protect the real identity of a person from the point of view of security, most of the cases of withdrawing money by changing ATMs in India have started where a person can withdraw money by knowing the password from behind and tricking you by changing your ATM But now biometric devices like fingerprint scanners are being installed on some ATM machines, which will withdraw money only after doing your biometric verification instead of a password.
There is someplace where a biometric machine is installed to prevent the entry of unauthorized people, where the gate opens only after your biometric verification is done.
Through this, such people can also be identified who are unable to reveal their addresses, such as small children. Aadhar card of every person is being made in India, which is based on this technology, in which the retina of the eyes and the house with their fingerprint. Address etc. information is also fed and if a child is lost due to any reason and his/her Aadhar card has been generated then his identity and address can be traced in seconds.
Biometric Attendance System (BAS) or Biometric Attendance is also being implemented in offices, school colleges so that people are present at their place on time and the system is improved.
How the Biometric System Works
Most optical fingerprint scanners are used to collect biometric data in the biometric system, in which the person's fingers are scanned by placing them on the scanner, then this fingerprint scanner is the fingerprint data in software. After this, the operator feeds these finger data along with other information such as name, address, etc., the next time someone places their finger on this fingerprint scanner Takes the image of his finger and matches the data with which the fingerprint data is already stored in the software, the information is revealed when the data is matched.
Optical Fingerprint Scanner
Optical fingerprint scanner uses the image to identify any fingerprint i.e. if a duplicate image is placed in front of it, it will also consider it as real as according to the news, instead of the original figure printed on the biometric attendance The rubber stamp of the key figure print is being prepared and used which looks like a real fingerprint optical fingerprint scanner.
Capacitive Fingerprint Scanner
Apart from this, the fingerprint scanner that is on your phone is a capacitive fingerprint scanner. It happens like the touch screen of your mobile phone works in exactly the same way and secondly, it makes a map of fingerprint in addition to its design, its bulge, and next time when capacitive fingerprint scanner. But if it is kept open, it quickly recognizes it.
