Introducing Cards 101: What You Need to Know About Payment Cards

February 18, 2026

Launching a card product can be overwhelming, even for those with many years of experience in the fintech industry. You may be a seasoned entrepreneur with a deep understanding of mobile payments, but not the economics of a card product. Or perhaps your area of expertise is in merchant acquiring rather than credit card networks and issuer processors.

Totavi has helped many entrepreneurs quickly get up to speed on launching a card product, and we usually start by presenting our Cards 101 presentation. We’ve had so many requests to share this presentation that we decided to make it available for free. We believe both Totavi and our clients are better positioned for success when entrepreneurs have a strong understanding of how card products work.

In our Cards 101 presentation, we cover:

  • Various types of card products, including consumer credit, commercial cards, debit cards, closed-loop, and open-loop programs
  • The end-to-end card transaction flow, explaining who’s involved when a card is swiped and how money moves
  • The economics of running a card program, including interchange, fees, and key cost drivers

Whether you’re validating a new card idea or preparing to launch a card program, Cards 101 gives you the foundation you need to make smarter product and partnership decisions.
