Fintech Decoded: The Free Glossary Every Aspiring PM Needs

120+ terms explained in plain English — from someone who actually works in fintech.

If you're trying to break into product management at a fintech company, there's one thing holding most people back before they even get to the interview: they don't speak the language. Card rails. 3DS. BIN analysis. Settlement windows. Chargeback rates. NIP. Correspondent banking.

These terms come up in job descriptions, PM interviews, and on the first day of any fintech product role. Not knowing them doesn't make you unqualified, but not knowing them when you walk into an interview does. This glossary fixes that.

What's inside:

120+ terms across 12 sections — Cards & Card Payments, Virtual Accounts, Mobile Money, FX, Stablecoins, Compliance & Risk, Fintech Infrastructure & APIs, Product Metrics, and more.

Every term includes a plain-English definition, a real-world example of how it shows up in product work, and where relevant, a PM Tip explaining why it matters for product decisions.

This was built from real experience shipping payment products at Flutterwave, not from a textbook.

This is for you if:

• You're applying for PM roles at fintechs and want to sound credible in interviews
• You just landed your first fintech product role and want to get up to speed fast
• You're in CX, operations, or engineering and want to transition into product
• You work in African fintech and want a reference you can actually use
