@sparfindig Back to this.

Even if Finland adopted the EPC QR codes officially. Implementation is afaik optional and when asking around in forums and chats I didn't find single instance of usage or anyone saying it would work. ;) Same of course applies to the payto:// URI scheme. Not working, not being used, not being offered, not present.

In Finland there's the "pankkiviivakoodi" - "bank bar code" which does contain payment information, but it's national standard and usually encoded using code128, yet technically of course nothing prevents storing the same data in QR code.
