Abstract
A system for providing specialized contacts for electronic information on a smart card or other device in the pattern of a source identifier, such that a machine may contact and read the information upon placement of the card in the machine. The contact points for reading information on the card are formed by etching a substrate attached to the logic element of the smart card. The etching allows both the foreground and the background of an image, in two selected colors, to be included within the contact area of the smart card, with the foreground constituting the conductor and the background the substrate. Additionally, the present invention provides electrostatic discharge (ESD) protection for a semiconductor circuit within the smart card without changing the appearance or method of forming the contact points.
