ITunes festival getting in with someone else's passsbook tickets?

A friend can't go to the itunes festival tomorrow for Paramore so she has given me her tickets.

I have loaded the tickets on to my passbook on my iPhone. The terms and conditions state that you ONLY need to bring the passbook tickets and photo ID.

The passbook tickets do NOT have any names attached to them. When they scan the QR code, does my friends name pop up on their machine? Or not? That's the only problem I see, otherwise I should be able to get in, and just show my photo ID.
