Visa

Visa makes money by taking a tiny fee every time someone swipes a card that has the Visa logo on it. They give the world a way to pay for things without carrying heavy cash. They won by convincing almost every bank and every store on Earth to use their “electronic language” for money. Their secret is that because everyone already has a Visa card, every store must accept it, and because every store accepts it, everyone wants the card. They use Network Leverage to run a Multi-sided Platform model through bank partnerships.
