How to Create a Wi-Fi QR Code for Guests

Use the guest network you intend to share

Choose a network that visitors are permitted to use. A guest-network label should not accidentally reveal the password for your private home, office or device-management network. If your router offers guest isolation, check its configuration in the router documentation; creating a QR image does not change network access rules.

For an original example, suppose a café has an SSID of Juniper Guest and a demonstration password of SampleOnly-7!. These are fictional credentials, not a functioning network. Real users should substitute their own authorized guest-network information.

Enter the connection fields without rewriting them

The tool escapes punctuation needed by its Wi-Fi text format. You do not need to add backslashes to the form fields. The supported workflow does not include enterprise EAP credentials or captive-portal login details.

1. Copy the network name exactly, including spaces and letter case.
2. Select the security used by that network: WPA/WPA2, WEP, or an open network without a password. Match the existing configuration; WEP is a compatibility option here, not a security recommendation.
3. Enter the exact password for a password-protected network. An open network has no password field in its encoded payload.
4. Select Hidden network only if the SSID is actually hidden.
5. Generate, then download PNG or SVG. If any input changes, generate the final version again.

Know what scanning does and what it does not do

BarcoBatch builds the QR in your browser. It does not contact the router, test the password or connect the scanner to Wi-Fi. A compatible reader may offer a network-connection action, but device and reader behavior varies. A successful decode is not proof that network authentication or internet access succeeded.

The QR Scanner can inspect the decoded text locally. Treat that decoded text as sensitive: do not paste real passwords into public screenshots, tickets or messages. The scanner reads the payload; it is not a router configuration tool.

Test before placing it on a counter or wall

Keep its clear border intact and follow the QR size and print-quality guide instead of assuming one physical size works for every payload.

• Scan the downloaded file, not just the on-screen preview.
• Check the intended network name and try joining with a visitor device.
• If scanning succeeds but joining fails, compare the actual SSID, security, password and hidden-network setting.
• If joining works but the internet does not, inspect the network or captive portal separately.
• Print one sample at the intended size and under realistic lighting before distributing copies.

Replace the image when credentials change

The downloaded QR stores fixed credentials. If the SSID or password changes, create and distribute a new image and remove old printed copies. Updating the router cannot rewrite an existing printed symbol. A hidden SSID does not make the credentials inside that image private.
