Ticket pickup at venues

[Livey~]

Hi guys~!

Today I'm going to my first ayu concert ever and I just can't wait!
But.. There's something I'm afraid of..

Some days ago I received an e-mail from iflyer with the instructions for the ticket pickup, and it says that I have to bring with me my TA Digital Fanclub ID. Does it mean that I just have to show it to them on my phone, or do I have to print it?
Same goes for the ticket.. I added it to Passbook, but will it be enough to just show it on my phone?

Thanks!
