Society requires new solutions to reduce the probability of COVID-19 cross-infection as people resume their daily lives. However, common touch surfaces have been shown to contain significant viral and microbial contamination. The SARS-CoV-2 virus can be present on plastic and glass surfaces for several days and multiple users of the same touch surfaces creates a continuous biological load that leads to cross-contamination, despite periodic cleaning.Studies have shown that touch screens of mobile phones belonging to medical staff in COVID-19 wards have a \>80% chance of containing the SARS-CoV-2 virus. It is almost certain that people with COVID-19 will have a highly contaminated mobile phone screens. If they then use public transport ticketing machines, the contamination will pass to that surface, as is the case with other forms of touch screen.A new form of transparent coating has been developed using vacuum coating that is extremely biocidal. These new anti-viral coatings will be tested on ticket machines used widely in transport, and thus break chains of transmission arising from numerous people touching the same surface.
