Designing a Guest Wi-Fi Sign People Can Use
A guest-network sign should identify the network, explain what to do and still help someone whose phone cannot read the code. Plan the words around the QR as carefully as the colors.
Use a guest network you intend to share
Enter the exact network name, security setting and password for a network you own or are allowed to share. A QR code does not discover an unknown password or bypass router security. Select an open-network setting only when the network really needs no password.
The pattern contains the credentials. Hiding the printed password does not encrypt the QR. Anyone who can scan it may read the details, so avoid putting a private-network code on a public counter.
Keep the sign and encoded fields in agreement
In the Wi-Fi card, edit network credentials in Content and the visible label in Design. Changing the label alone does not change what a phone reads. If the router password changes, update the draft, export a replacement and remove the old print.
Choose a reachable location and test
Put the sign within comfortable camera range and avoid reflective covers where possible. Use the print planner for paper layout estimates, then inspect the actual printed QR size. Test on a phone that is not already connected and confirm the correct network opens.
Some cameras offer a join action and others display raw data. A browser image scanner can decode credentials without joining the network. Device, router, guest-portal and enterprise-login behavior varies; this guide does not supply model-specific setup instructions.
