And not human readable, is my point. The value tradeoff in accuracy and compactness is the question. Will that be enough to sustain QR codes? I don't think so.
Also most QR codes seem to include a text url nearby the code anyway, so there goes the "compactness" argument. In that case it's redundant information as well.
