Most banks try to lure consumers with promotional offers like sign-up bonuses or 0% interest for a limited time. But some customers sign up for the card, take the offer and move on.
Banks can identify customers with this tendency by looking at credit reports, which show how many cards they've had and how often they open new ones, said Beverly Harzog, credit card expert at Credit.com.
While it likely wouldn't be enough to reject a customer if they have an otherwise perfect profile, it's still a strike against you, she said.
