 they conclude that using an open standard organisation like
 <a href="http://www.ietf.org/">IETF</a> is the correct place to
 maintain such specification.</p>

+<p><strong>Update 2016-03-20</strong>: Via Twitter I became aware of
+<a href="https://news.ycombinator.com/item?id=11319492">some comments
+about this blog post</a> that had several useful links and references to
+similar systems.  In the Czech republic, the Czech Banking Association
+standard #26, with short name SPAYD, uses QR codes with payment
+information.  More information is available from the Wikipedia page on
+<a href="https://en.wikipedia.org/wiki/Short_Payment_Descriptor">Short
+Payment Descriptor</a>.  And I Germany, there is a system named
+<a href="http://www.bezahlcode.de/">BezahlCode</a>,
+(<a href="http://www.bezahlcode.de/wp-content/uploads/BezahlCode_TechDok.pdf">specification
+v1.8 2013-12-05 available as PDF</a>), which uses QR code with
+URL-like formatting using "bank:" as the URI schema/protocol to
+provide the payment information.  There is also the
+<a href="http://www.ferd-net.de/front_content.php?idcat=231">ZUGFeRD</a>
+file format that perhaps could be transfered using QR codes, but I am
+not sure if it is done already.  Last, in Bolivia there are reports
+that tax information since november 2014 need to be printed in QR
+format on invoices.  I have not been able to track down a
+specification for this format, because of my limited language skill
+sets.</p>
