Abstract: A cryptographic medium including embedded metallic particles. The particles provide a unique signature when the card is exposed to a radio frequency signal. The medium includes programming and storage capability, so that protocols for different types of transactions may be stored on the medium, along with personal information associated with the user of the token. The token may take the form of a plastic card, which includes an electronic module fabricated using a multi-chip module design and including the programming and storage capability. The design allows greater computing and storage capacity on the card. At least the electronic module is encapsulated in a plascon material, giving the overall card a more physically secure construction.

Abstract: The invention concerns a method for managing faulty integrity of data inscribed in a re-writeable memory of an electronic component for carrying out operations capable of modifying at least one of said data and for exchanging data, either off-line directly with a terminal, or on-line with a transmitter through said terminal. The method consists in: defining so-called main data with faulty integrity representative of a malfunctioning of the memory, and so-called secondary data with faulty integrity representative, either of a malfunctioning of the memory or of a breakdown in the power supply of the component; carrying out, with each operation, integrity control for at least one datum; stopping the operation, in the event of faulty integrity of at least one main datum; attributing to at least one secondary datum a default value imposing an on-line exchange during the next operation, if integrity control of a secondary datum reveals faulty integrity. The invention is useful for making secure transactions carries out by means of electronic memory cards.

Abstract: This invention concerns a microprocessor with a control unit and a housing surrounding the control unit, as well as a chip card with such a microprocessor. Up until now, a significant weakness of the chip card systems has been that the microprocessor in the chip card which is surrounded by a housing, can be exposed for purposes of manipulation. Therefore, this invention aims to make a microprocessor and chip card available which are protected against manipulation. The invention achieves this task by providing the area of the housing of the microprocessor with at least one sensor which is linked to the control unit and indicates its environmental state. The control unit is constructed so that it can be set at an inactive state, if the sensor sends it one and/or no test signal which indicates a preset environmental state.

Abstract: An arrangement has a safety label (8) connected to the first chip (5) and at least partially visible from the outside which is arranged and designed in such a way that the integrity of the safety label (8) or of information displayed thereby may be recognised and/or measured by a chip card reader when a second chip is applied on the chip card, whether the first card (5) is removed or not from the chip card. The arrangement has the advantage of making it impossible or at least very difficult to replace the regular chip (5) or to add a second chip in an unnoticeable manner.

Abstract: The invention relates to a method for protected transactions involving a so-called smart card (11) and a terminal (12), such as a cash register. In order to prevent the smart card from simultaneously carrying out transactions with several terminals, the invention provides an authentication value (A) which is used in the data exchange between the smart card (11) and the terminal (12) to uniquely identify subsequent steps (e.g. I, III) of the transaction.

Abstract: The title device has a simple and inexpensive structure and can reliably execute a writing process only once even when receiving write signals repeatedly in communication between an antenna unit and a response unit provided in the mobile object. Receiving a write signal from a write antenna unit, the tag unit (response unit) executes a process of writing the data in the data memory on condition that the completion flag is cleared by a control circuit. When the writing process is executed, the control circuit sets the completion flag. After this, even if write signals are repeatedly received in the same communication area of the same write antenna unit, the control circuit nullifies the writing proces because the completion flat is set, hence preventing multiple writing.

Abstract translation: 标题装置具有简单且廉价的结构，并且即使在天线单元和设置在移动对象中的响应单元之间的通信中重复接收写信号也可以可靠地执行一次写入处理。 接收来自写入天线单元的写入信号，标签单元（响应单元）执行在控制电路清除完成标志的条件下将数据写入数据存储器的处理。 当执行写入处理时，控制电路设置完成标志。 此后，即使在相同的写入天线单元的相同通信区域中重复地接收到写入信号，由于设置完成平面，所以控制电路使写入过程无效，因此防止多次写入。
