Since the gas station doesn't know how much you're going to get, they "authorize" your card. Meaning they verify that the card is valid with either the bank or the card issuer.

There are ways to make the authorization succeed, but the final settlement (batch processing often) fail.

Hence pump-and-dash limits.
