Biometric systems quintessentially make use of unique human physical characteristics for the purpose of identification and verification of individuals trying to gain access into restricted areas. Most commonly, they check for attributes such as voice and facial patterns, eye scans and fingerprints. Ruling the roost among biometric devices are fingerprint scanners.
It is a known fact that no two fingerprints can be alike, and each fingerprint consists of unique patterns made out of ridges and furrows. A Fingerprint Scanner recognizes these patterns to identify the individual trying to gain access to a particular area or a piece of restricted information.
There are multiple reasons behind the raging popularity of fingerprint scanners vis-a-vis alternative biometric devices. Some of them are enumerated below.
1. When compared with devices such as those that use voice patterns for identification, it is evident that fingerprints are more secure. For starters, voices may be easily emulated and they tend to change with a person’s age and health conditions. An example of the latter is when an individual catches cold or suffers from a sore throat. On the other hand, fingerprints remain constant unless tampered with, thus mitigating the risk of access granted to unauthorized and fraudulent individuals.
2. Fingerprint scanners use high-resolution optical imaging systems to identify the finest of patterns, hence ensuring maximum accuracy in identity verification.
3. Today, these biometric systems are no longer bulky and can even be incorporated into touch-based smart phones and laptops. USB fingerprint readers are also commonly employed in medical information systems and e-commerce-based applications.
Because of these benefits, fingerprint scanners enjoy global acceptability among international immigration bodies and consulates. This adds to their image; if they are secure enough for security bigwigs, they become automatically desirable amongst corporate houses, government bodies and such other organisations.
