Payments look simple — tap, beep, done.
But behind that five-second moment is a whole system of banks, switches, and processors talking to each other in real time.
Whether you’re designing payment features, integrating APIs, or building a fintech product, understanding how that system works is fundamental.
Do you wonder what happens between tapping your card and hearing the confirmation beep? Or why bank transfers feel instant but settlement takes longer?
In this session, Olawale Ajiboye, a senior Scrum master and fintech professional who’s worked with NIBSS, Carbon, and First Bank, simplifies it all: how money really moves, who makes it happen and why every fintech builder should care.
