When identification and recognition of humans are based on their physical attributes, it is referred to as biometrics. It may involve fingerprints or DNA recognition or even iris recognition. Even one’s voice, gait or typing rhythm too at times serves as basic parameters for biometrics.
The process of biometric authentication through fingerprint matching is assumed to be the most successful and has become the latest trend all over the globe. A biometric fingerprint reader records the impressions left by the patterns of the ridges of the finger pads of a human being. A fingerprint is entirely unique to a certain person. Thus it authenticates people and stores the imprints to be matched further whenever required therefore assuring of the safest and most trustworthy method of verification. It has by far been the most reliable and accurate way of recognizing a person and has become an irrefutable parameter of identification.
With its growing popularity, today companies are coming up with new fingerprint readers based on newer technologies every day to make fingerprint identification process easier and hassle free. These USB fingerprint readers are equipped with optical sensors which are resistant to shock, corrosion or vibration and can sense the touch of a finger in its vicinity. The advanced technology ensures that under any circumstance, it can take a clear and distortion-free image of a finger irrespective of whether it is scarred, moist or even aged.
Fingerprinting is now utilized in many major areas. Airports, border security control, banks, schools, colleges, offices have currently resorted to fingerprinting. Fingerprint attendance has been adopted in many institutions including hospitals worldwide. Hospitals have even embraced fingerprint matching processes as part of access control. Biometric fingerprint readers are used to match previously recorded fingerprint data of the doctors, nurses and other staff of a hospital and permit their entry as that is the most secure method. Nowadays some hospitals even use the scanning and analysis of the sub-thermal palm vein patterns of their employees. This ensures that accurate identification is obtained even if there are cuts or abrasions on the skin.
