"Palm vein patterns are unique with each individual and aside from size, the vein patterns do not change over a person's lifetime. As the veins are internal in the body and have a wealth of differentiating features, assuming false identity through forgery is extremely difficult, thereby enabling an extremely high level of security. Furthermore, other advantages of palm vein pattern authentication include minimal impact from such factors as cold weather, injuries, skin chafing, and strong resistance to impact from changes in external environmental factors. Moreover, Fujitsu's system features contactless technology and does not require direct contact with the device. Simply suspending the hand in the air over the device is sufficient for reading and authentication. This hygienic feature makes it possible for numerous users to use the device without hesitance, as it is unnecessary to touch surfaces that others have come into physical contact with." [link]
