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?
Do the QR codes work without internet? The NFC payment schemes do.
It can work without internet only for amounts below 2000 rupees, and only if you’ve enabled that option.
How does the phone confirm the payment without a network? With NFC the phone has a low bandwidth connection to the payment terminal that’s enough to sign the transaction.
EDIT: I found it. It uses special phone codes that still use the mobile network to do the payment. If I understand correctly it would still not work in places where there’s no reception, like some large buildings or air planes.
Yes, you need a phone network, but not internet. Also there is a small charge.
