The Finge was already in development prior to COVID. The onset of Covid brought the need to avoid touching things that had been touched by others into sharp focus.
Currently this is achieved by wearing gloves but these to do not work very well on touchscreens; or using hand sanitisers after making direct contact with the contaminated surface.
The Finge provides a barrier for the wearer at the time of use but continues to provide a barrier when not in use as it is housed in a pot attached to a retractable lanyard.
