WiFi QR code: let guests connect without typing a password

Reading out a long WiFi password letter by letter, for the tenth guest that day, gets old fast. A WiFi QR code fixes that: a guest opens their phone camera, scans the code, and their phone connects on its own. No typing, no spelling mistakes.

How it actually works

The code stores the network name (SSID), the password, and the security type (usually WPA/WPA2) directly in the pattern itself. When a phone scans it, it recognizes the format and immediately offers to join the network - the data goes straight from the camera into the phone’s own settings, nothing passes through a server in between.

Where this comes in handy

Cafes and restaurants - print the code on a table tent or near the register so guests can connect in seconds.
Airbnbs and guesthouses - leave a printed code in a welcome folder or on the wall instead of a sticky note with a password nobody can read.
Offices and meeting rooms - visitors join the guest network without pulling a staff member away from what they’re doing.
Events and conferences - one sign on the wall serves hundreds of attendees instead of announcing a password from the stage.

Creating a WiFi QR code on qrkodi.is

Go to qrkodi.is and choose the “WiFi” content type.
Enter the network name exactly as it appears on devices.
Enter the password and pick the correct security type - WPA/WPA2 covers most modern networks.
If the network is hidden (it doesn’t show up in the list of available networks), tick “Hidden network”.
Download the code as a PNG or SVG, and consider adding a frame with text like “Scan to connect”.

A few practical tips

Print it large enough to scan easily from arm’s length - about 3x3 cm is a sensible minimum for a table tent, larger for a wall sign. Keep the code dark and the background light so scanners can read it reliably, and avoid placing it over a busy background pattern. If you’re mounting it somewhere long-term, like a reception desk or meeting room, laminating it will help it survive spills and daily wear.

One thing worth knowing: if you ever change the network password, you’ll need to generate a new code. The old one keeps pointing to the old password, since it’s static and holds the information itself rather than fetching it from anywhere.
