The Watchdog That Guards Money
Banks use AI like a watchdog — it sniffs every payment for something that smells wrong.

A Watchdog for Every Card
When a grownup uses a bank card, a tiny AI watches every time. It has seen millions of normal payments — coffee in the morning, groceries on Saturday.
If something looks weird — like a card used in two cities at once — the AI barks. The bank pauses the card and asks the grownup if it was really them.
Things the watchdog notices
- A card used very far from home
- A huge payment at a strange time
- Many tiny payments one after another
The big idea: AI helps banks spot weird patterns fast. It cannot tell for sure who did what — it just barks so a person can check.
