The Google Wallet NFC payment app, which was launched in the USA last year, has been transformed into a cloud-based service. Google Wallet was originally only available to customers who had a Citi MasterCard credit card or the Google Prepaid debit card.
The new cloud-based app supports all credit and debit cards from Visa, MasterCard, American Express and Discover - although it’s still only available in the USA. It means customers can use any card when they shop in-store or online - and also offers additional security, because the Google Wallet app now stores payment cards on Google servers rather than on the phone.
