Good question. QR codes needs for example a printer and stickers too, if
not printed directly on postcards. My new Epson printer, for example, does 
not support feeding of postcards or other thick materials, only standard
paper and photo paper.

Maybe we should ask ourselves why NFC tags were invented if QR-code would
be sufficient.
