Only problem with this is it discourages shifting to paper-less business. Remember when that was a goal of business and government. It's been so successful via the fact that it's simply easier than shuffling papers about. That being said, it is clever, sort-of a 255byte or so flash-rom storage on a piece of paper.

I think that things like migrating away from a paper-less society is best done in small steps. Who knows, things like these might actually speed up the process!

Some countries have already done it. It's not impossible or even that difficult if you get behind it.

I love the way in which LibreOffice can export a PDF with the original document still embedded. If a scannable code on a paper document could contain all the data needed to recreate it without any loss, you'd get effectively the same thing in a tangible form.

"This PDF is a Webserver, which will serve this PDF."

Is "going paper-less" a moral imperative?
