Imagine you’re at the supermarket checkout. Your cart is full. The line behind you is long. You tap your card. Declined.
You try again. Declined.
You haven’t overspent. You haven’t done anything suspicious. But somewhere inside your bank’s computer systems, a machine made a decision about you in less time than it takes to blink – and it made a mistake.
What just happened? And why does it keep happening to people who haven’t done anything wrong?
This isn’t a rare glitch, but something that happens to millions of people every day. And most of us have no idea why it happens or what we can do about it. The answer lies inside a fraud detection system powered by AI.
