Google officially rolled out its Google Wallet mobile payment system Monday. Is still in its infancy, but the system already shows a lot of promise.
It uses a technology called NFC (Near Field Communication) to securely send your payments digitally.
The only phone in the US that supports NFC is the Google Nexus S, available with t-mobile and Sprint, and there are high hopes that the iPhone 5 will support it too.
Right now, Google Wallet only works with Citi-Mastercards and the Google Prepaid Card. Visa and Google announced a worldwide agreement to support the Visa payWave app, but it will still be up to the financial institutions and banks to add support.
