In February, Bitcoin Magazine reported Google's preliminary announcement of Android Pay. In June, we reported the official announcement of Android Pay at the annual Google I/O event on May 28 and 29, where Google revealed more information on its upcoming payment platform.

On Thursday, September 10, Google announced that it is beginning to roll out Android Pay.

"We'll be rolling out gradually over the next few days, and this is just the beginning," notes the announcement. "We will continue to add even more features, banks and store locations in the coming months, making it even easier to pay with your Android phone."

Android Pay works with all NFC-enabled Android devices (running KitKat 4.4+), on any mobile carrier, at every tap and pay-ready location across the U.S. Android Pay will support credit and debit cards from the four major payment networks: American Express, Discover, MasterCard and Visa, issued by the most popular banks and credit unions.
