A new feature moving into Android 4.0, Ice Cream Sandwich is the Google Wallet. This allows a user to have a prepaid Google MasterCard with pay pass as well as additional bank, credit cards. Also the user will be able to add gift cards for various stores. This will all be accessed from the phone itself.

This system will allow shopping to become much easier.

The user will simply choose which card to use, tap the phone against the pay pass board, then input the pin, and voila the payment will be made!

The app can easily be installed on any ICS device and the device also does not need to be rooted in order for this to work. Simply go to XDA Developers and search for Google Wallet. Find the appropriate link, download the .apk and enjoy the new form of paying.
