The consortium has also forged partnerships with Visa, MasterCard, Discover and American Express and will use a technology known as near-field communication (NFC) to allow customers to make point-of-sale purchases by waving their smartphones over scanners. The service is scheduled to launch in the first half of 2012 on a limited basis in Salt Lake City, Utah and Austin, Texas before a full rollout.
