I'm really baffled as to why you're being down-voted. QR codes and RFIDs share some aspects in common, but the points you outlined are the most relevant differences. RFID also has the issue of discoverability. In order for someone to know that they should scan for RFID, there would need to be some visual indicator. The only reduction in user friction would be the fact that they need not point their phone at the indicator.
