The vaccine passport will be an app that is linked you your health records so it will be difficult to counterfeit. You will pull out your phone and start the app and it will generate a QR code and that code will be read by a reader app the business has at a kiosk or perhaps another phone that will validate it by sending it to the health department database. The QR code will be different every time since it will include GPS coordinates and a timestamp and some randomized nonsense filler data, which will make it impossible to reuse a QR code.
(Law sponsored by Apple Computers. Don't got a smartphone? Now you're legally obligated to buy one... Good luck, since you're not allowed in any store. Also if you rootkit your iPhone they'll make sure your passport QR has error codes in it.)
