Google Wallet users can rejoice a little today. For today with the latest version of the mobile payment system, you'll be able to use any credit or debit card you wish, and take them with you from one device to the next.
Data and security are now all in the cloud, allowing you to sync your preferred payment method across multiple devices and keep track of both your online and in-store purchase's through Google's web Wallet.
Perhaps most importantly though, Google has upped the security ante, by allowing you to disable individual devices remotely. Check out the video in the source link below.
