That's what these covid passports are really about. The government already has info on you. A covid passport would allow them to see who is compliant, and shame the dissidents into falling in line. It gives them a scapegoat to get the public angry and distracted. "Look at these unvaccinated people, they are a risk to public safety...never mind that your now cattle, hate these people over here". They could also just change your status to infected if maybe you were guilty of wrongthink and nobody would really question why your being sent away to camp Granada until your "better".
