Hey Doug,
Thanks for reaching out!
The way the Event Tickets Plus QR Code check-in system works is that each ticket has its own QR Code.
So if you sell one ticket for the whole three-day series, then that ticket can only be checked-in one time.
To have three different check-ins, you’d need three different tickets.
There’s unfortunately no way to alter these facts at this time without some extensive code customization. 🙁
I hope this helps! Please let me know if there are any other issues or questions I can try to help with.
Cheers,
George
