How do I make sure that a ticket is not presented twice?
If you have multiple entries to a venue and you are concerned that people may try to use a single ticket to gain entry for multiple people, then you can use QR scanning of tickets to instantly set each ticket as used.
To scan the QR codes on priorbooking.com tickets, you will need a QR scanner app on any smartphone. These are freely available. In order for this to work, you will need an internet connection or mobile data available as the QR scanning technology requires this in order to connect with priorbooking.com to mark the ticket as used.
