Abstract
The present invention provides a method to prevent a fraudulent use of a credit card, a security pass card and the like. A computer system containing card account numbers is provided with corresponding security codes. For authorization of credit issuance or a security check, a computer operator feeds the account number to the computer which in turn displays the corresponding security code on a terminal display. The operator verifies that the card bearer has the same security code, thereby verifying that the card bearer is the true card holder.
