Glossary of Payment Industry Terminology

Comprehensive, complete, and easy to understand

We believe this to be the most complete glossary of payment industry terminology available anywhere. Candidly, we looked everywhere, and could not find anything that was complete AND user-friendly, so… we’ve written our own. You’ll also find these terms cross-linked throughout our site. Did we miss anything? We tried not to! But if you find a term we should add, contact us and we’ll add it!
