Finger vein authentication uses leading-edge light transmission technology developed by Hitachi to undergo pattern-matching and authentication. Near-infrared light is transmitted through the finger and partially absorbed by hemoglobin in the veins to capture a unique finger vein pattern profile, which is then matched with a pre-registered profile to verify individual identity.

Hitachi''s patented light transmission technology enables high-contrast vein "maps" to be captured without interference from wrinkles, lines, roughness, dryness or other imperfections on the surface of the skin. Only a small amount of biometric data is thus needed for pattern-matching, allowing Hitachi to deliver one of the world''s fastest and most accurate personal authentication systems in a small, affordable, and user-friendly package.
