For General Events
You do not need to print out your ticket. All tickets are attached as a PDF file to the confirmation email and can be scanned directly from your smartphone at the event.
If you prefer, you may print the PDF tickets and bring the printed copy to the event, but this is not required.
For Self-Check-in Events
If the event requires self check-in, you may not be able to print PDF tickets due to the event organizer's policy. In most cases, simply have the QR code ready on your phone for scanning at the event.
