一、Core Technology Revealed - Why the Finger Vein?
Finger vein recognition technology uses near-infrared light to illuminate the finger, capturing the unique internal pattern of its blood vessels. As a biometric feature located deep within the body, each person's vein pattern is entirely distinct—even identical twins possess different patterns. Compared to easily replicated or worn fingerprints, environmentally susceptible facial recognition, and passwords prone to forgetting or leakage, finger veins offer a safer, more reliable “living key.”
By capturing the unique patterns of the subcutaneous vein network for identity verification, it offers the following significant advantages:
Inherent Uniqueness: Veins lie deep beneath the skin, their patterns determined by DNA. They are unique to each individual and remain stable throughout life, making them extremely difficult to replicate or steal.
Liveness Detection: Clear imaging is only possible with normal blood flow, effectively ensuring the subject is alive and preventing spoofing attacks.
Contactless Experience: No direct sensor contact is required, enhancing hygiene and user experience while preventing device wear.
Wide Applicability: Unaffected by skin surface conditions (dryness, moisture, damage), it offers excellent adaptability for the vast majority of individuals.
