Actually untrue. So in Windows Phone 8.0, they implemented Wallet, which was supposed to allow for carrier-sanctioned NFC payments. That unfortunately never came to pass other than a few small markets worldwide. In WP 8.1, they've pulled out any functionality for NFC payments from the Wallet app itself. This way, carriers can make their own app that controls this sort of stuff. My guess is that's a concession to the group formerly known as Isis, which involves T-Mobile, AT&T, and Verizon for the US markets. Still, nothing has panned out yet.
