Fingerprint Scanner Does Not Scan All Clients

Modified on Thu, Jun 21, 2018 at 3:43 PM


  • The Fingerprint Scanner does not work well on about 6 to 8% of people. Some professions such as machinist, dock workers, doctors, nurses, and cooks have damaged skin from chemicals, scarring, burns, and near constant hand washing removing natural oils.

  • For these clients, the salon can use the little finger instead of the index finger. They will just need to scan the little finger in place of whatever finger they normally use.

  • The client can also use a small amount of hand moisturizer - not sanitizer this can dry the skin further - to replace some of the oils.

  • You will also want to ensure that the scanner is clean.

Cleaning Fingerprint Scanner

  • You can safely use a tissue, paper towel or cloth to wipe down the window. To remove stubborn dirt, you can wipe the window with a cloth dampened with a soap solution. Squeeze out excess liquid before wiping with the damp cloth.

  • Cleaning agents like glass cleaners and anti-bacterial wipes may be used without harming the sensor. However, as with most plastic material, the housing of the unit may be damaged if strong solvents, acids, or caustic solutions are used.

  • Do not pour liquids directly onto the sensor or device, as the liquid might seep into the underlying components and cause damage.

Apply the sticky side of a piece of adhesive cellophane tape on the window and peel it away. If necessary, gently wipe the window with a cloth (not paper) dampened with a mild ammonia-based glass cleaner to remove any milky haze.

Never do the following:

  • Clean the reader window with paper.
  • Pour glass cleaner directly on the reader window.
  • Use alcohol-based cleaners.
  • Submerge the reader in liquid.
