Google announced at the Mobile Money: Delivering Innovative Mobile Payment Services panel during Mobile World Congress that Sprint will introduce “at least 10 additional phones” with Google Wallet support in 2012, Fierce Mobile Content reported on Thursday. The Samsung Nexus S 4G is the only smartphone currently offered by the carrier that supports Google’s NFC mobile payment system. Both the Galaxy Nexus and the LG Viper will launch with Wallet support later this year, however, and Osama Bedier, vice president of Google Wallet and Payments, said Google is continuing talks with other carriers, device manufacturers, banks, financial service providers and point-of-sale technology vendors to further extend the company’s Wallet network.
