Google: In May, Google revealed a contactless payment system called Google Wallet. Citi, MasterCard, Sprint and First Data partnered on the effort to make an app that enables mobile payments and loyalty cards using NFC. At first, it will support Citi MasterCard and a Google prepaid card and be compatible with the Nexus S 4G.
Amazon: Amazon is also exploring an NFC-enabled mobile payment system.
Apple: One of the most popular Apple rumors of late is that the iPhone 5 will be NFC-enabled. The same rumor turned out to be false regarding the iPad 2.
Microsoft: Not one to be left out of a party, Microsoft is also rumored to be planning NFC capabilities for its next phone releases.
PayPal: The company has partnered with Bling Nation, a Palo Alto startup that has been installing contactless payment terminals at local merchants since 2008. When users attached an NFC-enabled sticker to their phone, they could swipe to make payments and receive rewards. Previously, Bling Nation users were paying from accounts at partner banks. Since last summer, they’ve also had the option to pay using their PayPal accounts.
Credit card companies: Contactless payment stations that use cards can easily accept payments that use NFC as well. Thus, pretty much every major credit card company that has started the process of distributing payment stations to provide tap-and-go payments using cards is also interested in NFC-enabled payments.
Mobile phone providers: Verizon, AT&T and T-Mobile partnered to launch an NFC contactless payment network called Isis last year. Initially, it was partnered with just Discover. Since then, Visa, MasterCard and American Express have signed on.
