So the QR string could be
In 2012, the Austrian payment facilitator STUZZA4 (now part of PSA Payment Services Austria) defined the content of a QR code that could be used to initiate money transfers within the Single Euro Payments Area.
In February 2013, the European Payments Council (EPC) published the document 'Quick Response Code: Guidelines to Enable Data Capture for the Initiation of a Credit Transfer'. 5
These guidelines were quickly adopted by the Austrian banks. These QR code can be recognised thanks to the words "Zahlen mit Code" (Pay with Code) on the right.6
These guidelines were later on used in Finland in 2015,7 Germany in 20158 and the Netherlands 9 in 2016.
