I'm in this space in Germany, where such ideas are always taken to their logical extremes. The current push towards creating some kind of standard for electronic invoices (which would allow for a standardized data package to be transformed into QR) is called ZUGFeRD. http://www.ferd-net.de/front_content.php?idcat=231 http://www.ferd-net.de/front_content.php?idcat=231 The Zip(?!?) Containing the specification can be found here: http://www.awv-net.de/updates/zugferd/zugferd10.zip http://www.awv-net.de/updates/zugferd/zugferd10.zip This is a push towards adding data to the PDF Metadata that would allow for digitally reading of that electronic invoice by financial systems. The current problem, from my reading, is that there is not enough players that see a positive ROI for implementing this standard on a wide scale on systems where it would make sense.
