QR Invoices + PDF Orders

[ADPSuisse]

Hi there, 

My boutique is based in Switzerland and we are now obliged to provide QR Invoices to our customers. 

I would need to be able first to export PDF orders (don't know since only CSV seems to be permitted) and to make sure that at the bottom of the first page of the order there is a QR code section for payment, see picture below :

Is this possible?

If so how?

Best regards
