For anyone interested, the wifi QR code format is described here: https://www.wi-fi.org/system/files/WPA3%20Specification%20v3...

These QR codes usually work with your device's default camera app -- point at QR code and get prompted to join the network.

I created a few stickers with my guest network WiFi details QR code to put on my fridge and around the house for when I have guests. I also recommend writing the SSID and password on it for those times the QR code won’t work with someone’s device (usually my mom’s ancient Android phone).

That’s great! I’d love it if every place adopted this approach—then I wouldn’t even need to build this app.
