Vaccine passport, coming up.

Maybe, people who got the vaccine need to show id or end up end up wearing a visible patch to enter grocery stores.

You need to register for everything this day an age. Heck, you give your name, e-mail and phone number when making reservations. 

What's wrong with taking down information for contact tracing should a customer end up testing positive. 

Then the vaccine is widely available, you'll certainly need one when travelling. That's a forgone conclusion.
