MUMBAI: Google Wallet, the long-awaited digital wallet, is likely to be officially launched as early as tomorrow.

Google Wallet allows ‘one load credit cards to its app‘ and taps Near Field Communications-enabled phone to a special reader to buy anything.
 
Currently, the only phone compatible with this service is the Nexus S 4G and the only credit card firm to support the technology is Mastercard. Compatible terminals in retail outlets are still very rare.

This situation, however, is expected to change as more mobile providers and credit card firms embrace the technology.
