I've got a good mate who follows Newcastle home & away. He was telling me they have some new person who is doing this role there. They have been sending out electronic tickets for away games, but deliberately leaving a percentage deactivated, so that when peope get to the away end entrance the ticket doesn't work, they then have to go to the ticket office and show ID, to prove they are the same person who bought the ticket. This has been causing issues where people have gone with their kids, the kid has scanned their ticket and gone in first, then the parent's ticket is deactivated so they can't get in, and have to go and get the ticket activated, leaving their kids on their own in the ground.
He's gone home & away for years and is talking about now sacking the away games off.
