Yesterday we made a post about Google Wallet. if you are excited to try it, now you can. If you have an NFC enabled device like Sprint Google Nexus S you can download the Google Wallet App and start using google wallet.
more and more phones are adding NFC features so expect one day that all the phones will have NFC just like phones having wifi's today. I wonder if Google will make a Google Wallet app for Nokia, Windows Phone 7 and iOS devices.
if you have an android phone with NFC(as of now Sprint Google Nexus S phone only) just go to the Android Market and search for Google wallet.
here's a video made by Google about Google wallet
