How to use QR codes in meetings, slides, and presentations
If a meeting QR code needs a second explanation, it is already too hard to use.
A meeting QR code is only useful if people can scan it right away. In live rooms, failures usually come from size, clutter, contrast, or timing, not from the link itself.
Treat the QR code as part of the presentation flow
The code should support the presentation, not compete with it. Put it where people can find it immediately.
If it is buried under charts, logos, and footnotes, people will still scan slowly even when the link is correct.
Optimize for distance, not for your laptop screen
Do not judge it only from your laptop. Stand at the back of the room and try to scan it from there.
Contrast, empty space, and a direct mobile destination matter more than visual polish here.
Keep the destination specific and useful
A meeting QR code should lead to the next thing people actually need: the doc, the signup page, the event detail, the handout link.
If the room expects immediate action, do not send everyone to a generic homepage first.
For meetings, the basics carry the whole thing: make the code large enough, easy to find, and direct after the scan.
