It may not be a revolution but anything that replaces QR codes is a step in the right direction. It's much more intuitive to tap, swipe, or just be near something than to interact with a QR code.
Not that I have anything against NFC -- it's a rather interesting technology, with many useful applications that QR codes don't have. But QR codes have several properties that NFC doesn't, and by definition can never have.
