BitFlow Backs FF-OCT Fingerprint Scanning System

BitFlow Backs FF-OCT Fingerprint Scanning System

BitFlow is starting to promote a new fingerprint scanning system based on optical coherence tomography, or OCT. The system was pioneered by researchers at the Langevin Institute in Paris, and essentially analyzes patterns of interference that arise when light reflects on the rough surface of the finger. By going a step further and comparing images…
