A brief summary on how to create QR-codes from Zeffi answering links
You can create QR codes directly from Zeffi.
Once you have completed building your survey, go to the Deliver tab. There you can automatically generate QR codes from the default share link as well as from other share links.
We recommend using the default link for testing purposes only and creating a new share link for actual use. You can generate the QR code from the statistics box of the link, located in the top right corner. The QR code button is next to the "Copy link" button and looks like a QR code icon.
