I was in an AirBnb and I the internet password was written on a blackboard by hand on 3 rows with somewhere around 20 characters. Because my attention span is low, I was able to connect to internet after 5 attempts. I wrote somewhere to look for a way to make a QR code for connecting to WIFI when I get home. To my surprise, the technology existed for a few years already, but I never encountered it in real life. This is how I ended up writing this QR code generator API that can be integrated on any UI. I started a small journey for what useful things can be done with QR codes and I think I cover most of them in here. This project is open source.
