Give guests the right Wi-Fi connection

A café table card or hotel reception sign can spare visitors the task of typing a network name and password. This generator places those connection details inside a static Wi-Fi QR symbol. Prepare a separate guest network first, then reproduce its settings accurately. The picture contains credentials that anyone with access to it can read; treat displaying it as sharing the password.

Prepare the guest network before the sign

For a small café, use a guest SSID such as Cafe-Guest rather than the network that serves payment terminals or staff computers. Confirm isolation and access rules in the router settings; generating a code does not configure the router. Copy the exact network name, including capitals, spaces and punctuation. Check the password with a device that has not already saved the connection, since a remembered password can hide an incorrect test.

Match security and hidden-network settings

The available security choices are WPA / WPA2, WEP and an open network. The protected-network option writes the conventional WPA payload token. There is no dedicated WPA3 or enterprise authentication option here: do not assume that a WPA3-only configuration will work on every phone. Confirm compatibility on the intended devices or provide manual connection instructions. Select the hidden-network checkbox only when the router actually hides that SSID.

Print a card that can be maintained

Generate the image, download PNG for a simple document or SVG for scalable artwork, and place it beside a readable guest-network label. Keep the white border free of decorative frames. Test the finished table card at the distance guests will use it, including through any acrylic holder. A hotel should test both reception lighting and room lighting before repeating the card across many rooms.

Replace credentials and old copies together

Changing the router password does not update an already printed symbol. Generate a replacement after a password, SSID or security-setting change, and collect the old signs. A common failure is leaving last month’s card on a second counter. Keep a short inventory of where cards are displayed so that a scheduled password rotation does not become a series of guest support requests.

Common questions

Does scanning connect every phone automatically?: The receiving camera or Wi-Fi application interprets the payload and may ask for confirmation. Operating-system versions and network security settings differ, so a successful decode alone does not prove that joining will succeed.
Can I keep the Wi-Fi password secret?: No. The credentials are embedded in the symbol and can be decoded. Use a guest password suitable for sharing and control guest access in your router rather than relying on the picture to hide it.
Why does the code scan but joining fail?: Compare the SSID, password, security choice and hidden-network state with the router. Also check whether the guest network is enabled and within range; the QR image cannot repair connectivity or a captive portal.
What happens when I change the password?: The old image keeps the previous value. Create and print a new version, remove stale copies, and verify one fresh connection before putting the replacement cards back into service.
