NFC how widespread is this technology (I mean in mobile devices)? And does it have potential?

Question

NFC

Or will they come up with something better than nfc?

Answer 1

Bluetooth can also be attributed to NFC, the conclusions are appropriate :-) Regarding identification (pass) and payment (Paypass and others like it) - it happens in phones, especially in top models. The potential is very sickly, but it depends on the software and those to whose devices the phone is applied.
