Abstract: The method involves arranging a memory unit and a non-volatile memory unit on a wafer. Identification data to be stored in a radio frequency identification tag (201) are stored into the former memory unit using a data supply unit during a storage phase. The data are transferred parallel to the former memory unit and are durably stored into the non-volatile memory unit during another phase. The tag is isolated after the latter phase.

Abstract: An identification data carrier has a substrate as well as a resonant circuit structure, which is formed on or in the substrate, for an electromagnetic resonant circuit. The resonant circuit structure has a resonant frequency which is specific for an object to be identified. A read apparatus for reading object-specific information which is contained in an identification data carrier has, an electromagnetic radiation source for emission of electromagnetic energy in a predeterminable frequency range, a detection device for detection of the electromagnetic energy which is absorbed by a resonant circuit structure of the identification data carrier at different frequencies in the frequency range, and for determination of the value of the resonant frequency of the resonant circuit structure, a determination device for determination of the object-specific information which is contained in the identification data carrier, from the value of the resonant frequency of the resonant circuit structure. An identification system has at least one identification data carrier as well as a read apparatus having the features described above. In a method for producing an identification data carrier, a resonant circuit structure for an electromagnetic resonant circuit is formed on a substrate in such a manner that it has a resonant frequency which is specific for an object to be identified.

Abstract: The invention relates to an electronic component that can be operated by means of an alternating voltage. Said component includes at least one input, at least one output and a pair of electronic sub-components with an identical function. The input(s) of the electronic component is/are coupled to a respective input of the electronic sub-components with an identical function and the output(s) of the electronic component is/are coupled to a respective output of said electronic sub-components. In addition, the electronic component is configured in such a way that at least one output only one output signal of the first sub-component of the pair of functionally identical electronic components can be picked up during a first half-wave of an alternating voltage, whereas only one output signal of the second sub-component of the pair of functionally identical electronic can be picked up during the second half-wave of the alternating voltage.
