ABSTRACT:
A method is disclosed for verifying that a check user, a credit card holder, or an account user is authorized to complete a transaction. The issuer of the check or credit card or the verifying entity assigns a security code formula to each user, consisting of two variables: a base code number separated into two parts; and one or more arithmetic modes. The authorized user will calculate a verification code number in a two step process using the two parts of the base code and the check number or transaction amount; he then places it on the check or the transaction slip. Verification can be performed by the issuer, who ensures that a correct verification code number has been entered on the check or transaction slip.
