Abstract
A process for printing ID cards having a uniquely encoded security authentication component, where an ID card is created having a unique covert code embedded thereon that includes a verifiable fingerprint, which allows the card to be authenticated. A code is included into the image printed on the face of the card that contains important and relevant information pertaining to the time and place of card issue such as the printer manufacturer, issuing authority, time at which the card was printed, date when the card was printed and the printer serial number. The code uses specifically identified printed pixels in a predictable location on the face of the ID card. The pixels in the code location have specific colors that correspond to numbers.
