A field guide for displays
QR Code
Turn a display into a link people can take with them. Choose what should happen after the scan, then test it from where people will stand.
For a permanent link, a high-contrast QR image on a slide or printed sign may be enough. For a display that changes, use a browser-based tool so you can replace the code and its caption from your phone or laptop.
Choose what the code opens
01 Choose a destination
02 Leave a clear margin
03 Test from the room
A QR symbol encodes a payload. A web link needs a working destination. A Wi-Fi code carries network details that a compatible scanner may interpret as a join prompt. Treat anything on a public screen as visible to anyone nearby.
Compare the options
Static image or slide
Use it for A stable web link, offline playback or a backup printed sign.
Keep the original image square and preserve the blank margin. Replace the slide when the encoded payload changes.
QR to a URL you control
Use it for The same symbol can stay up while the linked page changes.
The URL stays encoded. Keep ownership of the destination, check its redirects and test it on a phone outside your internal network.
Browser-based display
Use it for Change the visible caption and switch between a web link and guest Wi-Fi.
The display needs an online browser. With V U This, publishing QR content requires a Pass. A static image is simpler for a permanent code.
Working example · V U This
Best fit for changing the code on an online display
V U This lets a paired controller choose a URL or guest Wi-Fi details, add a caption and show the code on a connected display with a Pass. Use “Scan for the schedule” or “Scan to join guest Wi-Fi” so people know what will happen. For a fixed sign, use a static QR image and a short printed link.
