Palm vein technology uses the unique vein patterns in individuals' palms for biometric identification and authentication. An infrared scanner reads the vein patterns and converts them into encrypted data points for verification. It has a very low false acceptance and rejection rate due to the uniqueness of palm vein patterns. Some applications of this technology include ATMs, laptops, passports, and areas requiring high security. Its advantages are high security, low cost, and lifelong usability. However, it is still relatively expensive compared to other biometric technologies.
