Finger vein reader is a biometric device that comprises at least one optical imaging unit designed to capture finger vein patterns of an individual and a digital signal processer that digitizes the captures finger vein patterns to be utilized as biometric features.
Finger vein authentication, introduced by widely Japanese banks is claimed to be the fastest and most secured biometric method.
The finger vein reader is as small as most fingerprint scanners (39 x 34 x 15 mm) and the raw data are processed to yield a small template. Because the device is measuring the light absorption of hemoglobin, it will only work with a live finger or hand.
Finger vein advocates counter that the transillumination of the fingers redness its vein pattern features to be highly distinct band enables greater accuracy.
Nevertheless finger vein systems do have at least some specific, incontestable advantage over hand vein systems –numerical superiority. Fingers have a 5:1 numerical advantage and 10- fingers offer a variety of application options.
In terms of research, it is easier to build a bigger pattern database. This is a big advantage because the number of people using such system increases, so the testing database of samples must be much larger than in the past.
