Biometric is the science of identification and recognition of humans on the basis of their physical attributes. The parameters for such identification vary from fingerprints to retina, from iris to voice.
However, over the years fingerprint has emerged to be the most useful parameter for biometric recognition. This has made the world sit up and take notice of the efficacy of a biometric fingerprint reader. Though initially developed for criminal identification by intelligence agencies, a fingerprint reader is today very much a part of every industry and corporate house which aims to safeguard its intelligence resource.
A fingerprint reader scans the impression left by the patterns of the ridges on a human finger and then matches it with the sample data already stored in the system. Now the patterns of the ridges in the human finger are extremely unique in nature. It has been observed that even the fingerprints from two different fingers form the same hand fail to give a match. This unique nature of fingerprints makes a biometric fingerprint reader the safest and most trustworthy device as far as verification is considered.
Moreover, with the advancement in the science of biometrics, new-age products such as a USB fingerprint reader and the like have ensured deliverance of clear and distortion-free images from even wet or scarred fingers.
As discussed earlier, fingerprint readers are no longer restricted for use by the federal agencies. Today, the method of fingerprint matching finds extensive application in a wide range of systems, one of the most popular being fingerprint attendance systems and access control systems. For instance in a clinical research organization the research laboratories become a restricted area meant to be used by researchers and authorities only. In such a scenario a fingerprint reader successfully serves the purpose of restricting admittance.
Also, in clinical trial studies, often cross-study participation of patients is not allowed. In these cases as well, a biometric fingerprint reader can be used to scan and enrol fingerprints of patients.
