Fingerprint Scanner Types
shows how collagen pushing between blood vessels creates ridges in the finger tip.

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
