Why NFC on phones? (sh.itjust.works)

Sometimes on phone reviews I read that a certain model, often one released in a Western market, uses NFC for payment. In my country, mobile payments use QR codes so any phone with a camera can use them. Does NFC have any advantage over such a system?

It's faster than a transaction via QR code. Also, the chip isn't just restricted to handling payments. It can be used as key fob for your car or on your smart lock at home or at the hotel you're staying at.

My car uses UWB (BMW Digital Key Plus) to automatically unlock when I'm walking towards it, once I'm pretty close. Maybe 1 meter (3 feet) from the car, in any direction. It has NFC as a fallback too - if the UWB thing fails for some reason, I can tap the phone to the door to unlock it too.
