Multi-spectral optical fingerprinting using multiple, different images taken on a single reader
during a single finger placement offers the following advantages:
• Multiple authentication images at enrollment and during authentication
• Multiple scanning wavelengths
• Different optical geometries
• Surface and subsurface feature identification
• Surface penetration up to 1500 microns deep (1.5 mm)
• “Single reader, single finger placement” for authentication
• No extra user actions
Blood Vessels
Surface ridges form by
collagen pushing between
the blood vessels
