(I ask because I worked a polling precinct on Tuesday and 99% isopropyl was how I disinfected the smartcards that unlocked the BMDs for voters and then got passed back to us; it definitely did not evaporate instantly on those cards).

I'd be interested in knowing whether anyone with expertise on this subject has thoughts on it. The boy is a biochem junior (and in my living room, because of coronavirus) and he doesn't have a firm answer on whether it would or wouldn't work.
