What are the differences between the “split” e-ticket option and the “combined” e-ticket option?

During checkout, you can choose whether to have your e-tickets delivered as a “combined” e-ticket or as a “split” e-ticket.

When you select a combined e-ticket, you receive a single QR code which is valid for all of the admissions (of a given type) you purchased for the event.

When you select split e-tickets, you receive multiple QR codes, one for each admission you purchased to the event.
