Google Wallet  


        A digital wallet  is an app on your phone or other mobile device that allows you to store virtual versions of items you would normally find in a physical wallet, like credit cards, bank account information, gift cards, coupons or customer loyalty cards, and even things like event tickets and boarding passes.Google Wallet is a mobile payment system developed by Google that allows its users to store debit cards, credit cards, loyalty cards, and gift cards among other things, as well as redeeming sales promotions on their mobile phone. Google Wallet can use near field communication (NFC) to "make secure payments fast and convenient by simply tapping the phone on any PayPass-enabled terminal at checkout."

Google demonstrated the app at a press conference on May 26, 2011. The app was released in the United States only on September 19, 2011. The service works with the 300,000 plus MasterCard PayPass merchant locations, with Visa licensing their Visa payWave system to Google for use in Wallet as of September 20, 2011. On May 15, 2013, Google announced the integration of Google Wallet and Gmail, allowing users to send money through Gmail attachments. Like the main service, Google Wallet's Gmail integration is also currently only available in the US, to those 18 or older.

To get started, one must download the Google Wallet app to their smartphone or tablet. Only a smattering of Android mobile devices have NFC as of mid-2013, but by 2014, some experts expect about half of smartphones to ship with NFC chips, and Forrester Research foresees more than a quarter of phones in the US having the technology by 2016 However, even if one’s current phone has NFC, cellular carrier must also enable the device to use NFC with a digital wallet, and most carriers are not doing this. As of June 2013, only Sprint, Virgin Mobile, US Cellular and Metro PCS offered any smartphones that work with Google Wallet and NFC in the U.S. These include devices from Samsung , LG and HTC. The Google Nexus 7 And Google Nexus 10 tablets also allow to use NFC.

If one doesn't have a compatible phone and carrier, they can sign up for Google Wallet online. The service can be used to speed through checkout at sites all over the Web.
Once downloaded the app or signed up online, set up Wallet with , loyalty cards,gift cards, credit cards and more and there will be  the option to pay with whatever source  chosen by the user . Of course, to use Wallet at all one need to find stores that actually have the equipment to read the NFC chip in their phone.
