I might be an idiot but... how about automatic doors? (that you don't have to touch)

You want some WiFi app thingie? Ok, link the automatic doors to the nearest gel dispenser and when the ratio of door opening/dispenser use gets too low, the door only opens after the dispenser has been used.

Hospital doors are used a lot. Automatic doors tend to break or fail unsafe, have limited fire protection and are expensive to maintain.

My brother-in-law sells doors to hospitals by a wonderful coincidence. Heard so much about the damn things it's depressing.

Big Brother class 0 is the automatic doors don't open till you sanitize (connected over wifi). Or your phone/tablet disconnects from the wifi network 5 minutes after sanitization.

Big Brother class 1 is your smart wifi nametag displays how long its been since you used hand sanitizer for everyone to read.

Big Brother class 2 is it also goes on your permanent record for review time and of course malpractice lawsuit time via wifi.

Big Brother class 3 they kill the infected you and spin up a new instance.
