If you mean physically hand over cash or tap your card at the turnstile itself then absolutely not.
This would seem to the easiest way to do it, or am I missing something?
Ordinarily on a match day you can’t hand over cash or tap your card at the turnstiles. You have to queue to get a ticket at the window located where the home end snack bar used to be near fanzine / Iron Trust corner, or go and get one from the main office. I imagine there is a reason for this, and I don’t see it changing for the Play Offs.
