Google will make Android Pay available for use with American Express, Discover, MasterCard and Visa corporate cards “later in the year,"

a Google spokesperson confirmed to BTN. The mobile-payment platform is compatible with AT&T, T-Mobile and Verizon, as well as nine banks, including Bank of America, Chase, Citi and U.S. Bank. It can work at any of the 700,000 near-field communication terminals in the United States, but Google has signed on just 20 retailers and 20 Android applications. It will add more “every day,” according to Google’s blog. To use Android Pay, users unlock their phones and tap them on the terminals. Once Android Pay launches, Google Wallet, which additionally requires a user to open an app and enter a pin code, will relaunch as a peer-to-peer payment app. Google Wallet is the only mobile wallet compatible with corporate cards, though Bank of America in May said it could enable Apple Pay for corporate card clients as early as this year.
