Wi-Fi QR

How it works

What happens when you scan it?

A Wi-Fi QR carries the network name (SSID), password and security type in the standard “WIFI:” format. iPhone and Android cameras recognize this format and show a “Join network” button.

Since the password is stored in the code, feel free to use a strong, long password; nobody will have to type it by hand.

The network name and password are case-sensitive. Type them exactly as shown in your router settings, including spaces. For hidden (non-broadcasting) networks, check the “Hidden network” option.

Tips

For best results

Set up a guest network separate from your main network; the code will be in everyone's hands.
When you change the password you'll need to print a new code; old codes won't work.
Write the network name and password in small print next to the code; it's a fallback for older devices.
Write “Connect to Wi-Fi” as the frame text so the code's purpose is clear at first glance.
For open networks, choose “No password” as the security type.

Before printing

Print the code at least 2 × 2 cm; make it bigger as scanning distance grows (about 1/10 of the distance).
Use a dark pattern on a light background. Some phones can't read inverted codes.
Don't crop the space around the code; the quiet zone is needed for readability.
Send SVG to the printer; as a vector it stays sharp at any size.
Test the final print file with at least two different phones.

FAQ

Wi-Fi QR

Which phones support it?

iOS 11 and later and Android 10 and later connect with the built-in camera. Older devices may need Google Lens or a QR app.

Is my password safe?

The password is written into the code and anyone who scans it can see it; just like writing the password on the table. That's why we recommend using a guest network. We don't store the password when creating the code.

Does it work with enterprise (802.1X) networks?

No. Enterprise networks that require a username aren't supported by the Wi-Fi QR standard.

My password has special characters; is that a problem?

No. Special characters such as ; : \ are escaped according to the standard.
