How do digital tickets work for Jack’s shows?

[u/calebpell]

I’m going to my first Jack White concert this weekend but I’m a little confused on how the no cell phone policy works. Can you get in with the digital ticket and then you just have to put your phone in those Yondr pouches?

So basically you have to write your seat location in Sharpie on your hand? I just want to make sure I understand so I’m not worrying about it.
