Infection protection

Antimicrobial coatings reduce the risk of infection significantly. Our coating approach and the use of copper(I) oxide as an antimicrobial agent are proven measures that not only kill bacteria and viruses but also do not impact the fingerprint quality, harm human skin, or damage the fingerprint scanner in any way.


Durable and robust against abrasion and cleaning



Nontoxic and non-sensitizing to human skin

Highest image quality

No loss in fingerprint quality


Copper(I) oxide is officially listed as biocidal agent in the European Biocidal Directive 98/8/EC

How does the antimicrobial coating work?

The antimicrobial coating is applied by using Combustion Chemical Vapor Deposition (CCVD) at atmospheric pressure. This process enables a gas phase reaction of inorganic particles. Copper(I) oxide is used as the antimicrobial agent. During the vaporization process the antimicrobial coating composition is applied to the fingerprint scanner. After several passes, the optimal coating thickness is achieved.
