24.5 Authentication unit (Biometric type) (AU-101)
• A finger vein pattern is used for personal identification.
• Vein patterns are inside the body and cannot be visually recognized. This makes vein
patterns extremely difficult to forge or falsify. The vein pattern authentication system can
provide high security.
• With ultra-red LED radiation, a finger vein pattern is captured by camera and its image is
created. The vein pattern image is registered and a person can be identified if the per-
son's vein pattern matches the registered one at the time of user authentication.
