Source for ticket QR code?

[aknocs]

Hello.

I'm trying to find the source for the string used in QR generation on the ticket, if it even exists in the database. We are providing our participants with a badge where they will have their public transportation pass and (preferably) their QR code for the event. We also need to send them the ticket in pdf format, beacuse not everyone will use public transportation.

I have not found a way to download the tickets in batch, and I'm hoping the source for the QR code is stored somewhere in the DB. If anyone could point me to the right table I would appreciate it.

Thanks in advance.
