This may go nowhere, but I'm being told (by my wife) that I should have a QR code on my CDC card I was given when I got my shots. All I'm seeing so far is the code is to verify you are able to get the 2nd shot, Moderna in our case. I got my shot at an on-site clinic at work, so no registering or pre-qualifying was done. They came back 4 weeks later to give us the 2nd shot and I was on the employee list and had my card from the first shot. They put a sticker showing the Moderna lot number in the 2nd shot line. With all the talk about Covid passports being needed in the future being possible, is my card with no QR code on it good? I saw on the news now that fake cards are being sold! May not be a thing right now but my curiosity has got the better of me and I'm looking for answers. I'll be asking at work tomorrow about this as well.
