Fingerprint Authentication System (cont’)
Proper Finger Placement
While the matching algorithm of the fingerprint authentication system is quite tolerant to non-optimum
finger placement, centering the core on the sensor will give the best possible performance.
The fingerprint ridges curve
around the tip of the finger.
The fingerprint “core”.
Find your fingerprint cores and verify that the core location of your fingerprints is approximately as
shown above. Most fingers will follow this general rule. If your core location is very different, adjust
your finger placement accordingly.
If the identification software can not find the fingerprint core, you may be able to solve this problem
simply by using a different finger.
The fingerprint “core”
is approximately under
the beginning of each
fingernail, or about half
way from the knuckle
to the fingertip.
