If the invoice issuer sends a QR-bill to his customer in paper form – in line with the financial center’s requirements – it is ensured that the financial institutions can process the payment part via all payment channels (e.g. in e-banking and m-banking, as a physical payment order or at the post office counter).
However, if a QR-bill is sent electronically as a PDF document and is to be further processed in paper form, the creditor must ensure that the relevant requirements are met. Essential requirements are (not exhaustive):
The size of the payment section must correspond to DIN A6 (105 x 148 mm); the markings and the scissors symbol serve this purpose.
The separation of the number part must be done according to the given lines
The paper must have a weight of at least 80 to a maximum of 100 g/m² (white or certified recycled, FSC and TCF paper).
Further requirements can be found in the documents "Implementation Guidelines QR-bill" and "Style Guide QR-bill".
