The whole idea of a smartphone is based on making some everyday tasks quick and intuitive as possible. In this Google Wallet is the result of a great idea, offering a quick way to make payments by credit card using NFC technology.
In its original version, though, this app has been hampered by a major limitation: so far, in fact, only the Citi MasterCard cards were supported while others were leaning to other software for the mobile payments.
Google has therefore, as had been announced, revised and corrected their app and then gaining the support of other credit cards such as Visa, American Espress, MasterCard and Discover.
The main reason for this shift was the change in the security system Google Wallet, major weak point of the app. The card data stored directly in the secure area of your terminal were significantly at risk so that the reports of security flaws have been manifold.
With the new version, Google Wallet move sensitive data in the cloud, on servers and super-secure Google data provide virtual credit card merchants with whom the transaction takes place, then adding a layer between the two levels. In addition to this you can either control which devices are permitted to transact and, if necessary, block the card immediately.
After this update is so refreshing to overcome one last obstacle, this time about the number of devices and is compatible with the app, for the moment, a list that is limited to rather narrow: Galaxy Nexus, Nexus 7, Galaxy S III, Ages 4G HTC, LG Viper, and LG Optimus.
