Abstract
A method of validating card numbers is described. A card number input by a user using a terminal device is obtained. It is judged whether an organization identity obtained from the card number is an identity of an organization that issues cards. A determination is made that the card number is invalid if the organization identity obtained from the card number is not an identity of an organization that issues cards.
