Facebook unveiled a “Donate Now” button on Monday to make it much easier for non-profits to take contributions. A nice side effect for its business? The button will collect credit card numbers and other billing info for Facebook that could aid its ecommerce and gaming initiatives. 19 non-profit launch partners will start displaying the Donate Now button at the tops of their Facebook Pages and bottom of their News Feed posts. These include DonorsChoose.org, Boys And Girls Club Of America, World Wildlife Fund, UNICEF, Red Cross, and Kiva. After some more testing, Facebook will open the feature to additional non-profits, who can sign up for access here. Thanks to the Donate Now button, instead of forcing users off Facebook and away from their friends, these organizations can now accept donations in a pop-up window right on Facebook.
