I think it would be a great addition to have a confirmation page that would display the ticket holders ticket information when the QR Code is scanned. Perhaps even having the information on the page editable.
An example would be:
1. At the top of the page, would be the ticket holder name
2. At the bottom of the page would be the event name and date.
3. In the middle of the page, either a large green checkmark, if the ticket is still valid, or a large red X if the ticket has already been scanned.
4. having the ability to have it show additional information on the check-in confirmation page would be great.
