Patent number: 5354097Abstract: An object or document, such as a credit card, passport, or bank note, is secured against forgery or fraud by the provision of a unique pattern of overlying individual fibers which are embedded in a sheet of transparent base material, and such that the fibers form geometrical configurations which are optically scannable through a surface of the transparent base material. The object or document is thus made unique and impossible to forge, and its authenticity may be verified by initially scanning the geometrical configurations with the scanned information being converted into digital data which may be compressed and encrypted, and then stored in a permanent memory. Following the distribution of the object or document, an inspector may scan the object or document and compare the obtained data with the stored date to thereby verify the authenticity of the object or document.Type: GrantFiled: December 15, 1992Date of Patent: October 11, 1994Assignee: Teunis TelInventor: Teunis Tel

Patent number: 5265916Abstract: Tickets for concerts, conventions, sports, and like events, have a security feature to assist in preventing counterfeiting. A stretchable security thread is disposed in a piece of paper stock extending so that it intersects, with portions lying on either side of, a line of separation in the piece of paper stock (and/or is parallel to the length of the ticket). The line of separation typically is a perforation. The security thread is a stretchable material, such as polyester, and may have microprinting. When the ticket is detached at the line of separation, the security thread does not initially separate but rather stretches to provide a visual (and tactile) indication between the separated portions of the paper stock before it breaks. Such tickets are produced from a web of material having the security threads, which web is printed, and then cut into sheets for delivery to a customer who then can apply variable printing.Type: GrantFiled: March 19, 1992Date of Patent: November 30, 1993Assignee: Moore Business Forms, Inc.Inventor: Robert P.

Patent number: 5250341Abstract: In an IC card and a manufacturing method therefor, an adhesive is applied between core layers in the vicinity of an opening in which an IC module is placed. The core sheet layers held between adhesive layers can easily be deformed when heat and pressure are applied. Therefore, a gap formed between the card substrate and the IC module is filled. Furthermore, the gap from the IC module is narrower at the corners of the IC module than conventionally shaped openings. As a result, gaps at the corners of the IC module after integral molding are prevented. Therefore, the gap between the IC module and the card substrate can be reliably filled during molding.Type: GrantFiled: January 30, 1991Date of Patent: October 5, 1993Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Makoto Kobayashi, Syojiro Kodai, Katsunori Ochi

Patent number: 4552383Abstract: A multilayer identification card is equipped with an IC module. The module is arranged on a carrier element which is located in a recess in the multilayer card. The card layers bordering the recess bear supporting layers which are thermoresistant in the range of hot laminating temperatures. This prevents the recess from becomming filled up with fluid card material during the hot laminating process, during which the card layers will soften and eventually become fluid. Thus, the IC module can advantageously give way within the recess when the card is bent. Further, the supporting layers have a stabilizing effect on the adjacent card layers and thereby prevent irregularities caused by incorporation of the carrier element from being passed onto the card surface.Type: GrantFiled: November 4, 1982Date of Patent: November 12, 1985Assignee: GAO Gesellschaft fur Automation und Organisation mbHInventors: Joachim Hoppe, Yahya Haghiri-Tehrani
