The future of secure authentication lies beneath the skin. The partnership between Rakinda and Evolute Fintech to deploy palm vein modules in mobile POS systems isn't just news—it's a masterclass in applied biometric security. Let's break down the technology.
How Palm Vein Recognition Works in a Handheld Device:
Infrared Scan: The POS terminal's module emits near-infrared light.
Hemoglobin Absorption: Deoxygenated hemoglobin in your veins absorbs this light, making the vein pattern appear as a dark contrast map.
Pattern Capture & Encryption: A specialized sensor captures this unique pattern, converting it into encrypted digital data (a template).
Instant Matching: During payment, a new scan is instantly matched against the registered template for verification.
Key Technical Advantages Over Other Biometrics:
Superior to Fingerprint Recognition: Vein patterns are internal, not left on surfaces. They are unaffected by minor cuts, dryness, or dirt—common issues with fingerprint scanners in rugged POS terminals.
Advanced Liveness Detection: The technology inherently requires blood flow, making it extremely resistant to spoofing using fake models or photographs.
High Accuracy & Speed: Offers a lower False Rejection Rate (FRR) and False Acceptance Rate (FAR), enabling fast, frictionless payments.
For fintech developers and system integrators, this collaboration opens new doors. Imagine building financial inclusion solutions for rural India with bank-grade security, or creating seamless retail self-checkout experiences.
