They are a placebo.


I got scanned walking into a store, the dude goes “92 degrees, you’re good”…. uh, sure.


I once entered a gov’t research facility as a contractor in like October of last year. It was in a cold area so it was already like 20°F outside. You park pretty far from the office then walk in the cold wind for several minutes until you’re inside. Your face is like 70°F by the time you make it to the scanner. No way it would show someone has a fever.


Where are they being used? I haven’t seen any in Ireland. Also i remember from the beginning of the pandemic that people were just taking paracetamol to get arpund showing any signs of fever.


And taking someone’s temperature doesn’t prove anything since there are a lot of people who are asymptomatic.
