A palm vein scanner is a biometric authentication device that uses near-infrared (NIR) light to capture and analyze the unique vein patterns inside a person’s palm. This highly secure and contactless technology is gaining popularity in banking, healthcare, security systems, and corporate access control due to its high accuracy, fraud resistance, and hygiene benefits.

How Does a Palm Vein Scanner Work?
Hand Placement – The user places their palm above the scanner without touching the surface.

Infrared Light Illumination – The scanner emits near-infrared light, which penetrates the skin and is absorbed by deoxygenated blood in the veins.

Vein Pattern Capture – The reflected light is captured as a unique vein pattern image.

Data Processing & Encryption – The system converts the image into a digital biometric template and encrypts it for secure authentication.

Verification & Access – The scanned pattern is compared to stored data, and if matched, access is granted.
