Between all of the different mobile payment platforms available, it can be a tough call choosing which one to focus on. Each have their advantages and disadvantages. If you are indifferent to the logistical differences between them, perhaps a different incentive might entice you to choose one. Google has teamed up with DonorsChoose.org, and will donate $1 (up to a total of $1 million) to special needs education projects.
This program will start today (November 24th, 2015) and will last through December 31st. On top of that, Google plans to double the amount of donations for each Android Pay purchase on Black Friday specifically. Now you can do some holiday shopping and help out the 6.4 million children in the US education system with special needs issues.
