Sanitizing for Enrollment and Scanning on Fingerprint Readers

Use Best Practices for Hand Sanitation of Users

Instruct users to thoroughly clean their fingers and hands with an alcohol-based sanitizer. Alterantively wash with soap and water for at least 20 seconds. This must be done BEFORE and AFTER touching the device.

Ensure that the fingers and hands are completely dry before touching the device.

During enrollment or  verification phase for instance

Use Personal Protective Equipment when Touching the Hands of a User.

When touching the hands of individuals that need to be enrolled/verified, follow your local Health Agency protocols for the use of Personal Protective Equipment (PPE).


Sanitizing Fingerprint Readers

The following advice has been provided for the cleaning and sanitizing of Idemia (Sagem/Morpho) biometric fingerprint readers. A similar approach can be used for most other brands as well.

First, please note that it is NOT necessary to unplug the device to clean it.

  • Thoroughly clean your hands with an alcohol-based rub or wash with soap and water BEFORE and AFTER cleaning the biometric device.
  • Always use a new pair of gloves when cleaning the device, and immediately dispose of the gloves once finished.
  • Regularly clean and disinfect the fingerprint sensor, especially after someone exhibiting COVID-19 symptoms touches the device.

From the US Environmental Protection Agency list[2] of disinfectants for use against the Coronavirus, IDEMIA recommends either:
Windex® Multi-Surface Disinfectant or another similar product containing L-Lactic acid; or
Hydrogen peroxide : apply the disinfectant to a non-abrasive wipe.

IDEMIA recommends either:
Economizer® Wipers; or 3M Scotch-Brite® High Performance Cloth
Wipe the device surface and leave the surface wet with disinfectant for at
least 5 minutes.


  • Do not apply products containing bleach to the fingerprint sensor. This may
    permanently damage and affect the performance of the device
  • Do not use abrasive cloths or wipes (e.g., paper towels)
  • Do not spray liquid directly onto the sensor. Always spray cleaning solution onto a
    non-abrasive cloth, and then use it to wipe the sensor.

Other manufacturers suggest spraying a light coating of sanitizer on the readers and leaving it to dry for a few minutes. It is important that you do not put so much on, that liquid actually runs into the device.
