Nice. For those wondering what Reed-Solomon codes are all about: they are extra data that allows certain types of corruption to be detected and fixed.
I believe RS codes are used on optical media such as CDs and DVDs which allows perfect playback with a few scratches here and there. They're also used in QR codes, so even if the scan is imperfect, the data can be reconstructed correctly. In the case of QR codes, the standard allows the QR code creator to set the level of error correction, providing a wide range of of data size vs resilience to corruption choices.
