Sprint and Google are launching the Google Wallet today to all Nexus S 4G customers, an app that enables consumers to transform their phones into their wallets and make purchases with a simple tap.
QSR first reported  on the creation of the Google Wallet in June, explaining how the service lets consumes tap-to-pay at hundreds of thousands of participating retailers , including quick-serve giant Subway.
“Sprint is thrilled to be the first U.S. carrier to offer Google Wallet,” says 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.”
Google Wallet  is a free Android app that stores virtual versions of a customer’s credit cards, offers and loyalty cards right on the one device they always have with them – their phone. At launch today, Google Wallet supports Citi MasterCard credit cards and the Google Prepaid MasterCard, powered by First Data.
Google plans to support additional cards.
Google Wallet is designed to enable safe, secure payments.
It requires users to set up a Google Wallet PIN that must be entered before making a purchase to prevent unauthorized access and payments.
“Shipping Google Wallet to Sprint is a crucial first step in creating a new way for people to use their phones to make shopping faster and easier,” says Osama Bedier, vice president of Payments at Google.
“The world is on the brink of the next big shift in payments, and today’s announcement demonstrates that we’re making real progress in attaining the vision we share with our partners for a new and innovative mobile payments platform. We believe this is just the beginning of a transformation that’s soon to come.”
