Fingerprint Readability
Fingerprint scanning is affected by a variety of factors, some that can
be controlled and others that cannot:
- Age - As people age, they lose collagen which
makes their fingerprint harder to read.
- Occupation - Manual laborers can sometimes wear
down fingerprints on one or more fingers.
- Ethnicity and Gender - Some women and
ethnicities have very faint fingerprints.
- Environment - Extremely dry environments cause
fingers to become dry.
- Hygiene - Frequent hand washing or use of
hand-sanitizers ca dry out the skin, making fingerprints harder to read.
People with difficult-to-read fingerprints may wish to press
slightly harder, hold their finger on the reader slightly longer, touch
their forehead before touching the reader (skin oils aid in
readability) or register and use one of their other fingers.

Taking Care of Your Fingerprint Reader
The fingerprint reader, while tolerant of residues left on the
reader, performs optimally when kept clean!
Cleaning U.are.U Readers
Apply the sticky side of a piece of adhesive cellophane tape to the
window, and then peel it away, OR
Gently dab the fingerprint reader window with a cloth that has been
dampened with a mild ammonia-based glass cleaner, such as Windex. (Do
not use paper!)
Protect Against the Risk of Damage to Your Fingerprint Reader
- Do not pour any liquid directly on the reader window.
- Do not use alcohol-based cleaners.
- Never submerge the reader in liquid.
- Never rub the window with an abrasive material, including paper.
- Do not poke the window coating with your fingernail or any other
item, such as a pen.
Proper Use of Your Fingerprint Reader
Most of the unique, repeatable fingerprint information is located in
the "pad" of your finger, not in the "tip". Flat finger placement as
shown below will result in fast and accurate fingerprint authentication.
