Update 2016-03-20: Via Twitter I became aware of +some comments +about this blog post 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 +Short +Payment Descriptor. And I Germany, there is a system named +BezahlCode, +(specification +v1.8 2013-12-05 available as PDF), which uses QR code with +URL-like formatting using "bank:" as the URI schema/protocol to +provide the payment information. There is also the +ZUGFeRD +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.
