I doubt that this would happen.
It could be done with "google glasses" like devices too, why do you think it will not happen? Because of existing laws or because there is no money for a big corporation to extract?
1 some people complaining that EU will block innovation if it is not allowed to do face recognition on public places or without consent. This people want to "disrupt/innovate"
2 we have the theory that people will wear masks so facial recognition is impossible
So 1 and 2 can't happen at the same time, if the guys from 1 need to innovate then they need no masks , if 2 will happen then the guys from 1 are complaining for nothing because the virus fucked up their disruptive ideas.
Sorry if I was unclear before.
