I bought a digital parking pass from ticketmaster for an upcoming event. It's a ticket I display on my phone meant for this garage. How do I use this?

I believe those passes have a QR CODE or bar code. You scan your pass to enter or pull a ticket. You scan your pass to exit once the event is over.

@Vel'Koz, Thank you for your question. Present the code to the parking attendant at the point of entry to the garage no more than 2 hours before the start of the event and it will be scanned and you will be allowed to park for your event.
