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 can 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.
