Taking Care of Your Fingerprint Reader

The fingerprint reader, while tolerant of residues left on the reader, performs optimally when kept clean!

How to Clean the U.are.U Fingerprint Reader

  • 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


Make sure you scan your index or middle finger, NOT your thumb.
