The 16 digits that make up your card are what we call a PAN. It's a certain number that you're most common to use—you know it and you see it because it's on your plastic card. A token is something we create. It actually works throughout systems, but we can create them and throw them away, then reuse them.... It's not as fixed as just that 16-digit number.
So when we create a token, like in the case of a merchant where...we replace PANs and we work with them to place tokens. If they are breached and the tokens are stolen, it doesn't matter. We'll just make new tokens. We will take away the value of the PAN—the credit card number—and replace it with a token, so we can just create more tokens.
