Palm vein technology uses the unique vein patterns in a person's palm for biometric identification and authentication. An infrared scanner reads the vein pattern and compares it to a registered template for verification. The technology is highly secure with a very low false acceptance and false rejection rate. It has applications in banking for ATM access, personal computers for login verification, and in hospitals and libraries for security and access control. The technology provides reliable and accurate identification without issues of forgotten passwords or codes, and no two individuals share the same vein pattern.
