So I guess the world is going to turn into a Renaissance Venice, but with masks made out of retro reflector makeup and IR LED wearbles instead of papier mache and mystery.
Secret speakeasies were easily revealed by speaking about them.
I'm also joking, but only partially. It could be a fun gimmick. Check all your electronics in at the door, go through the doorway with an EMP zapper, and then enjoy a distraction free camera free evening. You get banned if you get caught sneaking in electronics and you might wreck your expensive phone, so why risk it.
