Google launches Google Wallet, a service that uses wireless technology called NFC (near-field communication) to allow you to use your phone as a wallet. Wallet allows you to make payments at home with a single tap on the phone.
Google Wallet can store money on Google Prepaid Card and Citi Mastercard, for now. They can be loaded using almost any type of payment card on the market. Using NFC, the mobile phone can communicate with the cash register, obviously a compatible cash register, so you can make payment at the store.
Moreover, Google Wallet will synchronize with Google Offers, promotional service with offers from Google, not to miss anything interesting. However, there are two sad news. First, Google Wallet is now only compatible with the Nexus S 4G from Sprint. Second, Google Wallet will run only in U.S for now, until they will release it for the whole world. Many manufacturers have integrated NFC phone in their terminals. We are hoping that Google will get along with them, and make implementations of cash registers around the world, for the rest of us. If it will be as cool as it sounds remains to be seen.
The time when we will present ourselves with our phones rather than our ID Cards is getting closer.
