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 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.
Yes, you need a phone network, but not internet. Also there is a small charge.
