It's just a QR code so yes.This has probably been answered a million times but can't find it on here. With the "print at home" tickets - they accept it on your mobile I assume? I don't have a printer and CBA to go to a library just for that.
When you get to the turn style you will have to open the image of the QR code and hold it image side up under the scanner.
I have to say, queuing up for the turnstyles week after week after week watching people struggle to get in is my biggest stadium gripe.
They need to look at it as it's painful. There's always friction as well as you have people strugling to work it out then staff trying to tell them what to do and then there's arguments.
I regularly watch 5-10 people ahead of me struggle to get in then I waltz up, tap my phone and stroll in.
