CDC says those Covid vaccinated don't need to wear masks and can group together.  Won't those not vaccinated do the same then?

You can't. It will have to be on a trust basis.

You know how pets that are chipped, you can run a scanner over them and the owner’s information comes up. Same thing for people who got the vaccine.  For the Pfizer and Moderna second shot, there’s a chip in it so everyone that has gotten their second shot have been chipped. Run a scanner and that’s how you tell when someone has been vaccinated. In case you didn’t know, it’s a joke. That’s what anti-vaxxers and conspiracy theorists say about the covid vaccine. 

When you go to get your first shot, you’re given a covid-19 vaccination record card. It has your name, date of birth, your shot records, and where you got it. You’re told to bring it back with you when you get your second shot. Take a photo of it with your mobile phone after you get your second shot and you can use it as evidence that you’ve been fully vaccinated. 

No idea what the number that she’s covering up means. Could be the lot number. 

The CDC says you don’t need to wear a mask when you’re around family members who have been vaccinated. If you don’t know which of your family members have been vaccinated, then you got a problem. I know all my immediate family have been vaccinated except for 2. I also know which of my coworkers have been vaccinated since we all got it at work around the same time. 

Everyone gets a card that looks like what AOC has. 

This is a real problem. Now I know that my group of friends is vaccinated, and we are getting together. But I now feel that I need to tell people everywhere we go- restaurants, nail salons, etc. that we're vaccinated so we're not any threat to them. But anyone can say that, and all we have to prove it is this little card with handwritten initials and dates. We really need something more definitive from the CDC. You're suggesting that a lot of people will lie- I don't know that that's true- but you certainly do need to know and trust the people you get together with.
