The newly developed sensor by Fujitsu is unique for its compact form factor, being 5.2 mm thinner and 56% lighter than conventional sensors.
This makes it easier to incorporate into a broader range of electronic devices, including the thinnest of today’s notebook PCs and tablets. This, in turn, helps to expand the range of potential applications for palm vein authentication.

Compared to finger veins, palm veins are more numerous and create complex patterns, resulting in a higher volume of data. Consequently, the system’s recognition accuracy is extremely high, with a false-negatives rate of 0.01% (a single retry) and a false-positives rate of 0.00008%(3).
Furthermore, the fact that the system uses an individual’s thicker veins allows for stable operations over time. Lastly, the system is contact-free, helping to reduce any existing psychological burdens placed on users.
