On this episode of Payments Ground Game, we take a deep dive into the complicated, often misunderstood world of payment processing. Whether you’re new to the industry or a seasoned pro, you’ll appreciate their clear breakdown of what actually happens on the front end and back end of processing—from real-time authorizations to the nitty-gritty of batch settlement and clearing.

Elaina and Kevin use easy-to-understand analogies (remember Ma Bell and those old-school telephones?) to demystify how terminals, gateways, and virtual terminals communicate with processors, and why product certification to the front end is so critical. They’ll tackle the important distinctions between credit and PIN debit transactions, why reliability isn’t as simple as you think, and the real reasons those occasional outages seem to strike at the worst times.

On the back-end, they’ll explain why timing—like batching out at just the right moment—can make a big difference in your interchange rates, and what can go wrong if you or your processor slip up. Expect honest stories and industry insights about rejected transactions, interchange reclassifications, and the challenges of maintaining accuracy in a fast-changing payments landscape.

So, if you’ve ever wondered what “front end” and “back end” really mean for your business—and how your bottom line can be affected by everything from cut times to product certification—this episode will give you the tactical, real-world knowledge you need to scale your payments operation effectively.
