Like the original Google Wallet app that debuted in 2011, loyalty and reward cards can also be stored in the app. Tap-to-pay features will initially roll out in the U.S. and work with American Express, Discover, MasterCard and Visa cards issued by American Express, Bank of America, Discover, Navy Federal Credit Union, PNC, Regions Bank, USAA, and U.S. Bank.
Google says that Citi and Wells Fargo availability will follow shortly along with Capital One support as well.
Besides being available for download in the Google Play store, Android Pay will be pre-installed on "new NFC-enabled Android phones from AT&T, T-Mobile, and Verizon Wireless." Sprint is conspicuously absent from the list.
