Understanding is even club bought tickets will be QR code via UEFA app - so you will need the email address and UEFA logon details used to buy the ticket ( the club Email had a code and link to the UEFA website to buy a ticket) A code will be sent later that you key into the UEFA app to generate the QR code. I bought a ticket via the club yesterday and had to set up a UEFA logon to do it. It was also possible to add another order reference so the tickets would be close together if in the same category. Somewhat weird that a public ticket for the semi at Ibrox was more than the final ticket I bought yesterday.
