Wouldn't it stand to reason that you could be tested once per day, in the parking lot to a mall or some other shopping establishment, and thereafter _verify_ that you had been tested that day for the remainder of your commercial transactions?
Thinking in those terms, 10 minutes per day is not so great of an imposition. We could formalize it and create drive-through test centers where you drive up, spit into the tube, have a bar code on your phone scanned, and drive off. On your way to the mall you get a text message with your results. Everywhere else you visit that day scans your phone upon entry and confirms that you've been tested.
