    Abstract: 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.

    Abstract: The portable data transmission system is adapted to the contactless transmission of electrical signals and/or data between a smart card and a read-write station. The smart card has an electronic circuit with a data memory and an induction coil integrated in a smart card body. A coupling element is assigned to the induction coil and is disposed in a predetermined spatial position with regard to the induction coil. The smart card and the coupling element are respectively autonomous components which can be used independently of one another. A fixing element is at least partially matched to the outer dimensions of the smart card. The fixing element supports the smart card, on the one hand, and the coupling element, on the other hand, in the predetermined position with regard to the smart card.

    Abstract: The sensor device is provided for sensing biometric characteristics, in particular finger minutiae, with a biometric sensor chip. The sensor chip is fastened on a flexible printed circuit board that has a highly flexible substrate layer and conductor tracks applied to the substrate layer. The conductor tracks are in electrical contact with the sensor chip and are led to a terminal region of the flexible printed circuit board. The sensing area of the sensor chip is accessible through an opening in the flexible circuit board and the opening is at least partially surrounded by a grounding frame.

    Abstract: In a biometric sensor and a method for its production, a sensor chip is provided with connecting contacts in the form of electrically conductive bumps. The sensor chip is inserted into a chip housing, the bumps making contact with corresponding connecting leads belonging to the chip housing. At the same time as this contact is made, the sensor chip is bonded adhesively into the chip housing by an adhesive layer, which surrounds the sensor field in a sealing manner.
