Today I learned you can generate a QR that connects to WiFi.

The best part is that you can generate the QR code from your phone. It's a button in the wifi settings. Really easy way to share it from one phone to another.

You can also read the QR code from your Linux laptop.

Install zbar-tools and use zbarcam from the command line. It will read the QR code using the webcam, and now you have the Wi-Fi credentials.

Or any other data in the QR code.
