Abstract
Method and means are disclosed for providing and testing a secure identification medium on which is encoded uniqueness information and security information in addition to customer information. The security information is generated from the uniqueness information and the customer information by means of algorithm processing means and is then compared with the security information read from the record medium. The algorithm processing means is also employed in generating the security information in the first instance for encoding said information on said record medium initially. Failure in the comparison of the security information encoded on the record medium with that generated by the algorithm processing means provides an indication that the record medium is not a legitimate one.
