Google released Monday the first version of its Google Wallet app to Sprint. With Google Wallet, you can tap, pay and save using your phone and near field communication (NFC).

Google is now rolling out Google Wallet to all Sprint Nexus S 4G phones through an over-the-air update, with a $10 free bonus to the Google Prepaid Card. Google plans to add Google Wallet to more phones in the future.

Google Wallet enables you to pay with your Citi MasterCard credit card and the Google Prepaid Card, which can be funded with any of your existing plastic credit cards. Visa, Discover and American Express will be added to future versions of Google Wallet.
