Using QR-Code to transfer data from a BBC Micro

That’s an odd choice, but very interesting nonetheless. Thomas ten Cate decided to try to transfer his old programs from his beloved BBC Micro using QR-Code plotted on screen, and he reports his progress, problems and findings in a series of 6 articles on his personal blog.

As he explains, that “most QR codes are fairly small, as they contain just a web address or some such. But they can actually grow to the “Level 40” monster code of 177×177 squares, which can hold 2953 bytes of arbitrary binary data. That’s about 60 QR codes to transfer the contents of one floppy.”
