Do I pick up a physical ticket, or is mobile entry enough?

For most big K-pop concerts you still collect a physical ticket at the venue box office on the day, and they match your booking name to your passport. Pickup lines build for hours before doors, so get there early, especially if you booked through a global site that holds the tickets for venue collection. A few shows are moving to mobile entry, so read the specific event notice, but plan for in-person pickup unless it clearly says otherwise.
