It’s becoming normal to supply a trigger for electronic payments with a pdf invoice in the form of a qr-code. The qr-code contains a url to a payment provider.

Where should the information in the qr-code be placed in the UBL Invoice? I think it belongs in cac:PayementMeans but I can’t find a place for it.

For example the  cbc:PaymentMeansCode=68 and a URL in cbc:PaymentMeansCode/@name or cbc:InstructionID?

Or does the the term in cac:PaymentTerms/cbc:PaymentTermsDetailsURI because it is specific for this transaction.
