From authentication of face masks to PPE gear to disinfectant tagging to Covid nasal and saliva tests The bonus is they can authenticate the test just like the face masks, Dotz Vs Covid ding ding
The other tests coming through that use machines, I still think I'd rather put my trust in a simple solution that can screen hundreds of people at once. You think about the breath where they blow into the device, Covid is an airborn virus if people are exhaling air the vurus speads during testing, If its just a saliva or nasal test its quick and the person puts his mask back on. The.machine test is complicated and machines break, or go out of calibration
I'd put my faith in a visual test over a machine test anytime.
