Put the card where guests need it
An indoor welcome folder, desk, or kitchen information stand is a useful place for a Wi-Fi card. Label the code with the network name so guests know which connection it represents. Keep a readable copy of the network name and password for devices that cannot scan Wi-Fi codes. Avoid placing network credentials on a public-facing window or outside noticeboard.
Treat the image like the password
The QR image contains connection credentials; it is not an encrypted secret or a way to hide the password from recipients. Someone with the image may be able to read those details. When you rotate the password or rename the network, make a new code and replace every printed or shared copy. See the guest Wi-Fi guide for the full sharing workflow.
Match the code to the actual network
This tool supports WPA/WPA2 Personal, WEP, and open networks. Enterprise authentication and WPA3-only configurations are not included. A code cannot improve signal strength, configure a router, bypass a captive portal, or guarantee that every scanner will recognize a network payload. If your property uses a browser sign-in page, explain that extra step on the welcome card. The Wi-Fi QR generator describes the supported fields.
A quick check for this use case.
- The network name matches exactly, including capitalization.
- The selected security setting matches the router.
- A disconnected guest device can join successfully.
- Old cards are replaced when the password changes.
