Let people join a meeting, webinar, office-hours session, or classroom from a simple scan. A Zoom QR code is especially effective when you need to move people from a physical space into a live digital session quickly.
In many cases the destination should be the Zoom meeting or webinar link itself. If passcodes, time windows, or pre-read instructions matter, a landing page is often a better destination because it gives you space to explain what users should expect before they join.
