RE:Anyone following KNR needs to see this...
Yeah, it's a cute concept and all but how does cleaning the device affect the reliability of detection, what about amputees, or how does it help buildings that have inbound/outbound shipments making sure the environment itself is covid free? Say you got some packages delivered to your office that came from an unknown infested place, now you got that in your building and you won't know until x amount of time until little johnny and the crew mates scan their finger that may or not be reliable depending on how the unit is cleaned and sanitized hundreds and thousands of times a day. KNR set up to an HVAC system to continously monitor air is a much better system imo.
