Problem Correction
How to select finger?
Use the index or middle finger to enroll; try the left hand
fingers if the right hand fingerprints are worn, damaged
or missing. If the user’s fingers are small, select the
thumb.
Poor Fingerprint Definition
Some people have fingerprint definition that is too poor
to verify. These employees should use Proximity
badge verification.
Dirty or Dry Finger
Wash hands with moisturizing soap or use hand lotion

Damaged Fingerprint
Use alternate finger with backup fingerprint template.
Bad Finger Positioning
Place finger in the middle of the sensor; keep finger flat
on the sensor and apply firm pressure; DO NOT touch
the sensor in an angled or tilted position, DO NOT slide
finger.
Fingerprint pattern change
For a user with a worn or injured finger, the
identification can be affected. Use an alternate finger
or select Proximity badge verification.

fingerprint sensor. Using a fingerprint overlay on the
