CreateQR
I found a little source code on GitHub to create QR Codes. The Source is rather straight forward and simple with little changes, most about difference between Delphi and Free Pascal. So I created a little Version for Amiga, but not save an image as the original but print it to the console using the CRT unit with white and black background. It works nicely can scan with my iPhone.
