Abstract
Abstract This invention relates to a credit card and security system to prevent use of credit cards, identification cards and the like by other than the assigned holder of the cards by inserting identifying information in electronic distorted form pertaining only to assigned holder, hidden within the card. The system provides for the person checking the validity of the card to see it undistorted and to examine the hidden information, to determine positively if the person presenting the card is the assigned holder of the card and decide if the card should be honored.
