The limitations of QR codes, if we embed a URL, should be plenty, even without any compression, eg: http://osm.org/qr/21d906f1-7a93-49f5-beee-7c126b840a85 Although the QR code could be smaller if less error correction was used, or smaller pixels, or we could make them bigger and have the OSM URL underneath...
