  That reminds me a lot of a QR code, but extended. At which point, I have to ask: Why not just use QR codes? They have the advantage of being ubiquitous, although I'm very open to the idea that they have disadvantages or leave improvements on the table.

    The main advantage is information density. QR codes dedicate a lot of real estate to error correction, but the protocol is really optimized for a few words, not kilobytes at a time. It's also a problem if you need to segment your datastream onto multiple pages You've got to define a protocol for your stack of QR codes with that new encoding
