    摘要： The invention relates to a multilayer body, in particular a security element for safeguarding security documents with machine-readable coding. The multilayer body has a first layer of a dielectric material, a second layer of an electrically conductive material provided partially on a first surface of the first layer, and a third layer of an electrically conductive material provided partially on a second surface of the first layer located opposite the first surface. The second and the third layer are spaced apart from each other by less than 100 µm. In a first surface region (30), the second layer is shaped in the form of N first coil-like structures (71, 72, 73) and the third layer is shaped in the form of M second coil-like structures (61). The first and second coil-like structures (61; 71 to 73) each have different geometries and different, predetermined resonant frequencies, which provide machine-readable coding. Each of the N first coil-like structures (71 to 73) and M second coil-like structures (61) shaped in the first surface region (30) are arranged in relation to one another in such a way that, in the first surface region (30), each of the first coil-like structures (71 to 73) is arranged to overlap at least one of the M second coil-like structures (6) in some regions. The area center of gravity of the smaller-area structure of two first and second coil-like structures arranged to overlap in some regions is no further than D/2 x 0.5 from the outer edge of the larger-area structure (61) of the two first and second coil-like structures (61, 71, 72, 73) arranged to overlap in some regions, wherein D is the mean diameter of the larger-area structure (61) of the two first and second coil-like structures (61, 71, 72, 73) arranged to overlap in some regions.

    摘要： A method and system for reading information stored in a data carrier are presented. The data carrier comprises a collection of circuitries defining together a predetermined information code. Each circuitry includes: (a) a code circuit configured to have a certain RF frequency response to a powering signal and thus defining a certain symbol of the predetermined information code, and (b) a delay circuit configured to provide a phase delay of a predetermined value to said powering signal associated with the respective code circuit to thereby define a location of this symbol in the information code. The data carrier further comprises a power unit operable to produce said powering signal to actuate the delay circuit. The system comprises a magnetic field source for actuating the power unit of the data carrier, and an RF detector operating for sensing the RF responses of the RF data carriers, and analyzing frequency of the responses and their sequential appearance to identify the code pattern stored in the RF data carrier.
