Google launches its virtual wallet

It's official: Google is launching its new product, Google Wallet, which lets you pay for purchases using your smartphone.

The rumours that have been circulating over the last few days were well founded: Google officially launched Google Wallet this week, an innovation that comes after several months of testing, but whose use will initially be very limited. For the time being, its use is limited to the United States, and to customers of Citi bank, Google's partner. Above all, only one model of phone - the Nexus S 4G - can currently use the Android application thanks to NFC contactless payment technology.
