Sprint is the first carrier to offer Google Wallet, a new app/service that lets consumers pay using their smartphone. Sprint is initially supporting Google Wallet on the Nexus S 4G phone. The Google Wallet Android app stores virtual versions of a customer’s credit cards, offers and loyalty cards right on the phone. 
“Sprint is thrilled to be the first U.S. carrier to offer Google Wallet,�? said Fared Adib, vice president of Product at Sprint. “Nexus S 4G is the first to receive new versions of Android software, and today’s upgrade puts the near-field communications, or NFC, chip in the phone to work so customers can have a secure virtual wallet on their phone. NFC capabilities on smartphones open the door to a new level of convenience and security.�?http://www.sprint.com
