Moist fingers and thumbs give better images than dry ones. If on cold,
dry days you have difficulty, for example, try moistening your finger
or thumb with your breath or a little lotion.
Very dry, dirty, fingerprints with cracks going across them or scarred
fingers/thumbs are obviously not recommended, since they will
obscure the fingerprint.
Always wait until the fingerprint scanner
turns on
to place your
finger/thumb on the scanning window. This is true for both
fingerprint enrollment AND verification.
When trying to enroll or verify fingerprints in direct sunlight, be sure
to shade the sensor with your shadow, so sunlight will not reflect off
of the mirror in the sensor.
