The gist of this forum thinks that all of a,sudden apple comes out with nfc and in like 5 min it's the reason it took off and it's complete bull crap.
Nfc is where it is today because of SAMSUNG
Uh. No. If you want to get technical Nokia had NFC before Samsung. Anyway, NFC payment activity tripled in the US after the Apple Pay launch.
There are some questions, such as how this system will work when chip cards become standard in the U.S. The magnetic strips won't work if the payment terminal accepts chip cards. That's probably why it's coming out in the U.S. first. And even then it isn't going to work until the summer, with chip cards coming in August.
Also, apparently Visa and Mastercard were able to get this working with tokenization since they already did a lot of the back-end work getting Apple Pay to work.
