Yes! You can generate a QR code for your auction campaign's main page!
From your dashboard, click on "Auctions" and then "Manage" the campaign you wish.
Then, click "Settings" and scroll to the bottom of the page. You will see the QR code. Click on "Save Image." The QR code will now be saved to your computer.
Please note: if you change the URL (web address) of your Auction campaign at any time, the previous QR code will no longer work and you will need to download a new one.
