What Are Palm Vein Biometrics?

Palm vein biometrics, a relatively new player in the biometric security arena, uses the unique patterns of veins in the palm to identify individuals. This method stands out for its non-invasive, hygienic approach to personal identification, leveraging the fact that the pattern of blood vessels in each person’s palm is unique and stable over time.

How Do Palm Vein Biometrics Work?

The technology behind palm vein biometrics is sophisticated yet straightforward. When near-infrared light is transmitted through the palm, it is absorbed by the haemoglobin in the blood, making the veins appear as a black pattern against the lighter background of the palm. This pattern is then converted into a biometric template and stored for future comparison. The process is fast, secure, and, most importantly, non-contact, making it particularly appealing in the post-pandemic world.

Why Are Palm Vein Biometrics Gaining Popularity?

The rise in popularity of palm vein biometrics can be attributed to several factors, including their high level of accuracy, difficulty to forge, and the non-contact nature of the scanning process.
