The scanning process on a mobile phone?? is defo slower than just either buying a ticket or giving your ticket in. That's the problem here as they haven't taken on more staff to compensate, they have less staff if anything. Hopefully they will buy some more effiecent scanner machines at some point.
Mobile phone scanner very slow, I went in with my wife and teenage daughter (both first timers) and my sons season ticket holder friend. My son behind us was paying cash so was refused admission and told to join the queue at another turnstile. What was that about???
