What is a QR code good for?
One scan, and the visitor is on the page. Nobody likes typing a web address off a flyer, a poster, a menu or a newspaper ad. A QR code is scanned with a phone and takes people straight to the page, news item or event.
In the editor, open the ⋯ (More actions) menu and choose QR code…. It is there on every page, news item and event.
