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?
Oh yes I know cards use NFC. My question was about phones.
The reason why phones is: I don’t want to carry 50 cards with me when my phone can do it.
The infrastructure for cards was already there. So instead of replacing the infrastructure you replace the medium.
It works both ways.
I can tap my government ID card to my phone to identify myself on government sites.
