Hi HN,
Just wanted to share a simple - yet useful - tool.
It's able to decode a WiFi QR code and copy its password directly in your clipboard.
Usefull when you need to connect à new network and you've a WiFi QR code under your hands.
Just show the QR code in front of your webcam (required obviously) and the tool decode it for you.
The tool is open source so build your version if you does not trust mine :-)
Edit: It also respect your privacy as no data is sent anywhere and nothing is recorded, decoding is done "on the fly".
