For every Apple Pay transaction made at a retail location, online, or in-app around the world, Apple will make a $1 donation to the Global Fund, an international organization that aims to prevent and treat AIDS, tuberculosis, and malaria. In addition, more than 400 participating Apple stores will feature a red Apple logo over the next week, and today, people who visit the App Store will see a Today tab that features stories about HIV/AIDS.

Game developer King, (the maker of the Candy Crush games), is also getting in on the action for World AIDS Day—it has rolled out limited edition bundles of its most popular games, with all proceeds from in-app purchases going to the Global Fund.

Apple has already raised $160 million for the Global Fund as part of its partnership with (RED), including a record-breaking $30 million just this year. The latter amount is enough for 144 million days of ARV medication—the drugs that prevents the transmission of the disease from a mother to their unborn child. According to Apple, the money raised in the past 11 years to fight HIV/AIDS has helped provide more than 475 million days of the medication.

“Connecting through our products and services helps make it easy for our customers to join us in the effort to create the first AIDS-free generation,” said Lisa Jackson, Apple’s vice president of Environment, Policy and Social Initiatives, in a press statement.
