Your tickets will have been attached as a PDF (one attachment for each ticket) to your order confirmation email.
Simply bring your tickets on your mobile or handheld device. As you approach the event's point of entry, pull up your ticket on your device and make sure that the QR code is clearly visible as this is what will be scanned.
Of course, if you prefer to print your tickets, you are most welcome to do so.
