Yes, we provide a QR code for your general auction and a QR code for each item in your catalog.
Go to Event > Print Materials >Mobile Item Sheets, this will provide you with the general auction QR code on the first page and the item QR code on each of the items' pages.
If you would like just the QR codes without the item page that you can turn into stickers for your live event go to Event > Print Materials > QR Code Stickers.
