  • Communication is done by modulating a radio frequency signal in the frequency range of about 13.56 MHz. This results in signal sections with different amplitude. From this, a so-called modulation index can be calculated, which should be within a certain predetermined value range, in order to ensure the least error-prone communication possible. From DE 10 2009 009 846 A1 methods for operating a card reader and a card reader are known. This is carried out more advantageously to perform a communication with a contactless readable card according to the standard ISO / IEC 14443 Type B. In order to ensure that a modulation index, which occurs at close range in the presence of a contactless readable card, corresponds to a desired predetermined modulation index, the magnetic field is received and evaluated via a receiving antenna of the card reader. The modulation index is used for deviations between The measured modulation index and the default value for the modulation index are readjusted or regulated in order to approximate the measured modulation index to the default value.

L'invention concerne un document de sécurité (30) qui comprend un ensemble de circuits électroniques (40). Cet ensemble de circuits (40) comprend un système d'alimentation (150) servant à fournir une tension et/ou un courant électrique et une structure d'excitation (100). Le document comprend en plus une structure de sécurité (200) qui possède une couleur structurale (210) dont l'interaction avec la lumière peut être influencée par un champ électrique et/ou magnétique, de sorte que la teinte de la couleur structurale (210) dépend du champ électrique et/ou magnétique. Cette structure d'excitation (100) est couplée au système d'alimentation (150) et elle est disposée par rapport à la structure de sécurité (200) de telle façon que l'application de la tension et/ou du courant électrique fourni(e) par le système d'alimentation (150) dans la zone de la structure de sécurité (200) génère un champ électrique et/ou magnétique et provoque par ce biais une variation de la couleur de la structure de sécurité (200). L'invention concerne en outre un procédé de contrôle d'un ensemble de circuits (40) dans un document de sécurité (30).
