Patent number: 7012531Abstract: A product label includes a semiconductor chip and an antenna. The semiconductor chip stores information about a product. The antenna transmits the information about the product to a reading device. The antenna has a predetermined breaking point at which the antenna can be destroyed during the reading operation by energy introduced by the reading device so that the product label can be read only for a specific number of read cycles. A method of producing product labels and a method for a contactless, forgery-proof identification of products are also provided.Type: GrantFiled: June 7, 2002Date of Patent: March 14, 2006Assignee: Infineon Technologies AGInventors: Manfred Fries, Detlef Houdeau

Patent number: 6421248Abstract: A chip card module contains, in addition to conductor tracks and a chip carrier, one or more semiconductor chips and, if necessary, a stiffening frame. The semiconductor chip(s) and/or stiffening frame are attached with the aid of an adhesive, with which particles of a defined size are admixed as spacers. The adhesive in preferably a flexible adhesive, and the particles preferably are formed of a deformable material. The invention has the effect that the semiconductor chip(s) and/or stiffening frame are adhesively attached to the underlying surface at a defined, uniform distance. The flexible adhesive and the deformable particles adapt to deformations of the chip card module and thus prevent damage to the adhesively bonded mating surfaces.Type: GrantFiled: July 15, 1999Date of Patent: July 16, 2002Assignee: Infineon Technologies AGInventors: Hans-Georg Mensch, Stefan Emmert, Detlef Houdeau

Patent number: 6375083Abstract: A smart card with a card carrier on which a data processing circuit and also a connection assembly for the contactless communication of data between the data processing circuit and an external data processing station are provided. In the course of producing a prior art smart card, an integrated circuit is applied to a card carrier made of plastic. Afterwards, a transmitting/receiving coil connected to corresponding terminals of the integrated circuit is applied along the outer edges of the prior art smart card. In the case of the prior art smart card, the fact that defective prior art smart cards have to be destroyed is disadvantageous. According to the invention, the data processing circuit and the connection assembly are provided in a region of at least one module carrier and the card carrier has a region for accommodating the module carrier. This makes it possible firstly to test the completed module carrier in respect of its proper functioning before it is incorporated into a card carrier.Type: GrantFiled: July 15, 1999Date of Patent: April 23, 2002Assignee: Infineon Technologies AGInventors: Manfred Fries, Frank Püschner, Josef Mundigl, Jürgen Fischer, Detlef Houdeau
