I believe most people assume if they are using SFA tickets bought by a friend or family member, then they will be planning to check in to the Uefa app using the applicants login.
This is a breach of the SFA ticketing guidelines, but would be the only practical process as SFA tickets, unlike UEFA tickets, are non-transferable.
It means breaking the SFA rules, and would of course backfire spectacularly if Photo ID is requested to validate the ticket "owner" at the barriers or turnstiles.
The UEFA ticketing Ts and Cs ( please see attached below) are clear that photo ID, on our part, Passports, will be required.
it remains to be seen if this will actually be enforced on the day.
No issue transferring Uefa ballot tickets, but likely that this can only be done once?
