A short history
The format QR Code Generator generates wasn't invented as marketing gimmickry. It was invented to solve a real industrial inventory-tracking problem, with constraints (scanning speed, damage resistance, error correction) that still shape its modern uses.
Knowing the history matters in one specific way: it explains why some options in QR Code Generator look the way they do. Error correction, redundancy levels, quiet zones — they're all design decisions inherited from the original use case, baked into the spec, kept because they still work.
