Technology involving biometrics has long been used for security measures as well as convenience in identification. It is currently being used in workspaces, airports, and government documents around the world. 

How it Works 

Biometrics involves the process of measuring and identifying a person through his unique physical characteristics.

A person’s identity can be distinguished by a specialized machine through his or her fingerprints, hands, eyes, voice, signature, and other facial characteristics.

Thus, it offers a greater complexity of requirement for admission compared to passwords and codes which can easily be forgotten by the users.


Biometrics can easily identify a person without having to worry about forgetting numbers and codes. It is much more convenient than passwords as well as a physical ID because there are chances that it might be left at home or worse, lost. In offices, biometrics are used to input your time in and time out at work while just using your fingerprints. It is quick, convenient, and less hassle for users.

Issues in Biometrics

Many people have raised their concern against biometrics. Many were concerned about the physical changes that a person’s body naturally undergoes as they age that might not be recognized by the biometric. However, many have also defended its use by expressing that fingerprints, handprints, and eye characteristics do not deteriorate its uniqueness compared to other parts of the body. 

Unreliability of Biometrics

Another major concern that some have regarding biometrics is the threat of the utilization of fingerprint identifications which can possibly result in fraud and identity theft. Leaks and hacks will occur. Replication could exist too where the owner’s identification method would be copied that other users will also access even though it was unauthorized. So far, there aren’t any major cases where biometrics was used to instigate a severe crime.
