Android owners will soon be able to use their own mobile banking app — rather than Android Pay or Samsung Pay — to make tap-and-go payments in stores. Mastercard has expanded its Masterpass program to mobile devices so consumers can make contactless payments at various retailers. Mastercard first introduced Masterpass in 2014 to power in-app and online payments. Customer credit card data is stored in the cloud and tokenized for security, allowing people to make purchases with one click. Mastercard is extending Masterpass to its banking customers so those banks can add contactless payment capabilities to their own apps. Some of the first banks to support contactless payments include Bank of America, Capital One, Citi, Fifth Third Bank, KeyBank, People's United Bank, and Virginia Credit Union. Mastercard says 17 banks in total plan to add mobile payments to their apps in the near future. (One glaring omission at launch is JPMorgan Chase, which has so far shunned Android Pay. Chase is working on its own mobile payment service that has yet to launch.) Contactless, Masterpass payments will be available at more than 5 million retail locations across 77 countries that accept contactless payments via NFC. In the U.S., BJ's Wholesale Club will be among the first to support the bank-based mobile payment tool, with JetBlue, Saks, Lord and Taylor, Subway, and The Cheesecake Factory to follow shortly. It will be up to the individual supporting banks, such as Citi, to add contactless payments to their mobile apps.
