Well we've yet to test it but me and my mate have both got each others season tickets in our wallets now so they are on 2 devices.

But as I said that might be because we have each other as linked or friends and family or whatever.

You might not be able to put your season ticket on a second wallet/device if that person isn't part of your friends/family group.

I didn't even know about the friend/family thing until he sent me a request to link up with him that I just clicked on and it connected us.
