On the NHS app there are two parts to the Covid pass, one that says "Domestic" & one that says "Travel". I would imagine that you will have to scan the code to the domestic one. I can imagine that being chaos if you do that at the turnstile though. If people can't get online on their phone to get on to the app, which is possible if over 50k are all trying to do it at the same time. It would make more sense if you could prove you have had the jabs once and it gets linked to your account, so that you don't have to prove it every game.
I've had both my jabs but unless they come up with a workable way of getting into the ground I'll just sack my Season Ticket off, I'm not pissing about for ages every game trying to get in.
The first game is going to be carnage with a combination of that and not using season cards this year.
