Figure A-2 shows poor-quality fingerprints, characterized by smudged,
faded or distorted areas on the fingerprint. These conditions can be
caused by excessive dryness, wetness, insufficient pressure or scarring
of the skin at the fingertip.

The S900 fingerprint matching algorithm is capable of extracting the
correct minutiae without the benefit of a perfect print. However, the
positioning of the finger and the moisture and pressure of the fingerprint
are significant factors to consider when it is placed on the sensor. This
will help achieve a good consistent fingerprint match.
