    Abstract: A method of magnetizing a permanently magnetizable element associated with a magnetic field sensor structure includes generating a test magnetic field penetrating the magnetic field sensor structure and the permanently magnetizable element, detecting the magnetic field and providing a test signal based on a magnetic field through the magnetic field sensor structure, aligning the test magnetic field and the magnetic field sensor structure with the permanently magnetizable element to each other, until the test signal reaches a set value corresponding to a predetermined magnetized field distribution with respect to the magnetic field sensor structure, and generating a magnetizing field for permanently magnetizing the element to be permanently magnetized, wherein the magnetizing field corresponds to the predetermined magnetic field distribution within a tolerance range.

    Abstract: A chip card includes a semiconductor chip that contains at least one memory. In order to supply energy to the chip and to provide for bi-directional data transmission from and to the chip, both contacts and a device for contactless data transmission are provided. A triggerable switch device which is provided on the chip connects the memory either to the contacts or to the device for contactless data transmission as a function of a state of an output signal of a logic circuit connected to at least a voltage supply contact. The switch device assumes a position of repose when it is not triggered and in that position it connects the memory to the device for contactless data transmission, while only upon application of a voltage to the supply voltage contact, triggered by the logic circuit, does it connect the contacts to the memory.
