Android Pay is now available to everyone with a compatible device. To get more people to use the service, and in the spirit of the season, Google has teamed up with DonorsChoose.org to support special needs children in U.S. schools. Through Dec. 31, Google will donate $1 for every purchase made through Android Pay, with a total of up to $1 million. The money goes to an interactive classroom environment for kids who have trouble engaging. Android Pay will double its donations for every purchase made on Black Friday.
