Just to clear up misinformation and bullshit previously sprouted in this thread.
Pubs/shops can't increase the £30 maximum for contactless, Apple Pay etc can be over £30 because you are authenticating it with your finger/passcode.
There is a lot more hassle in running a cash gate than employing a school kid to run it for an hour.
There are many easy ways to bypass security if you are banned (unless very notorious) a mate buying you a ticket, wearing a hat and not sitting wear you normally sit would do the trick I'm sure. Might be different in ten years with facial recognition on CCTV etc but that ain't ever happening at Pittodrie.
Putting contactless payments at a gate is a decent idea, I'm sure the club has looked into the costs of hardware to select the ticket type, take the payment, print the ticket, software development and the fact it would also be quite easy to buy a kids ticket for an adult. The fact it is only used for 20 games a season and the technology could become dated quick it isn't worth it. It would probably have to be an already developed system that we purchased/rent from another company.
Cash has many benefits when you don't want HMRC to know what you spend your money on or how you obtain it.
Yo, fam. You miss this shit?
Once fully functional, you can Apple Pay on your phone, straight to wallet and straight in the door.
