I’m trying to reproduce the Qr Code that comes from the ticketing add-on on a custom Attendee badge. When I scan the qr code the Mobile app says (Invalid Qr Code).
What are the requirements for the qr code.
Can you tell me what is the Qr code you are using?
The QR code uses the Google Chart API to generate the QR code image.
As for data, it contains:
event_code
registration_id
attendee_id
If you take a look at the functions.php in the Ticketing addon on it may provide further information.
