Hitachi Develops World's Smallest Finger Vein Authentication Device

Tokyo (JCN) - Hitachi has prototyped the world's smallest device that has been able to authenticate an individual's ID based on his/her finger vein patterns. Applicable to notebook PCs and PDAs, the prototype measures 39x34x15mm, 1/20 the size of conventional devices.

The company has applied its proprietary biometrics technologies that it has worked on since 1997, to develop the flat optical authentication system that sheds light from the back of a finger and monitors vein patterns by measuring light transmitting through the finger.
