Google Wallet launches officially on Nexus S 4G
0
It's the 4G version of the Nexus S that'll receive the update to Google Wallet first, Google tells us, this brand new NFC-based electronic payments system working with Visa, American Express, and Discover right out of the gate. This system will allow you, as you may already know, to tap your device to an in-store payment device and instantly pay your bill with your "Wallet". Your update to full alpha Google Wallet functionality will occur in an over-the-air manner, meaning that if you've got a Samsung Nexus S 4G, you'll be seeing a notification right away immediately if not soon.
