Mastercard’s main business is providing payments card technology, but it turns out that the same tech can be used for much higher purposes: saving lives in some of the poorest countries in the world.
The big picture: Thanks to a partnership between Mastercard and Gavi, the global vaccination alliance, children will be given a "digital birth certificate" that looks a lot like a standard credit card. That card can then be taken into any clinic, which will be able to see exactly which vaccinations the child has received and which shots are still needed.
