After a summer of testing in a few US cities, Google Wallet has finally been taken out of beta and and is currently rolling out (as an OTA update) only to the Sprint Nexus S 4G, but extra phone support is promised.
Google Wallet works with Citi MasterCard credit cards or the Google Prepaid Card (if you get a G-card by year end there's a $10 bonus for you) and allows people to pay for various services or products by simply tapping their NFC-enabled smartphone on terminals compatible with MasterCard's PayPass technology. In the future Google is hoping to add support for Visa, Discover and American Express cards as they all provided their NFC specifications to allow for such an expansion. For now though, Google Wallet is in the baby steps phase, but check out the demo below.
