I purchased a combined e-ticket for myself and my friends, but not all of us will be arriving to the event at the same time. How can I send my friends their e-tickets if I only have one QR code for all of the e-tickets?
Your combined e-ticket QR code will be scanned by the door staff at the event for as many times as the e-ticket is valid for admission. So, you can simply send a copy of the combined e-ticket to your friends.
So, it is not necessary that you all arrive at the venue at the same time for use of your e-ticket, however (in the example) only the first 4 uses of the e-ticket will be recognized.
Therefore, you should only forward your e-ticket emails to confirmed and trusted guests in your party.
