- This is our Knowledge Center. It's an encyclopedia to help illuminate the complicated payments industry. Anyone can contribute to it, improving its accuracy, quality, and objectivity, which means it's a work in progress. It's a lot like Wikipedia for payments. You can read a bit more about why we started this Knowledge Center.
