Since adding support for all major credit cards, Google Wallet adoption has grown by more than double. The company announced the news on Thursday, highlighting the added benefit and convenience of being able to use any card through the service. There’s an obvious interest in mobile payments without that prepaid element, and it’s reflected in Google Wallet’s growth. The service is still in its infancy, and adoption isn’t exactly widespread among retailers. But it sounds like interest is growing among consumers, which might one day lead to becoming the dominant form of payments in the future.
