Fujitsu, which is good at identity recognition, recently launched their latest product - a new identity recognition system, which uses metrological biology knowledge and combines palm vein recognition and fingerprint recognition. Together, it only takes 2 seconds to identify a user from millions of people. Different from the general fingerprint recognition system, this system requires the input of fingerprints and vein information of the users three fingers, but it can achieve more accurate identification. In addition, this system is modular, that is, the vein recognition system can be added to the existing fingerprint recognition system to expand the functions of the original system.
