Google officially released its first Google Wallet service today, an Android app that turns your smartphone into a mobile payment system.
The app enables people to pay via credit, debit and other cards strictly through the phone. At launch the service works with MasterCard but Google announced Monday that Visa, Discover and American Express have been added to the service and could be available in the future.
Google introduced Google Wallet in May, but until now, only employees of Google and other companies involved with the app have been able to use it. Google will focus at first on signing up merchants and users in New York and San Francisco, but Sprint Nexus S 4G users will be able to use it in other cities at 150,000 merchants that accept MasterCard’s PayPass, Google said.
