How does the smart card technology in metro works?
I'm interested in learning about how smart card technology works in metro systems. Can you explain that to me?
Sure, I'd be glad to help! Smart card technology works by storing information on a microchip embedded in the card. When you tap the card on a reader, the information is transmitted wirelessly to a computer system, which then deducts the fare from your account.
