A data carrier (1, 2), in particular a plastic card, has an authenticity feature (4) introduced thereon, which can be customized during radiation with a high-energy beam. The customizable authenticity features (4) consist of at least one magnetizable component, wherein the customizable authenticity features (4) are magnetically formed. The intensity and/or wavelength of the radiation is selected such that the customizable magnetic authenticity features (4) undergo a localized structural change during irradiation, wherein the magnetizable components of the customizable magnetic authenticity feature (4) are at least partially destroyed. Following the irradiation, the customized magnetic authenticity features (4) form an area of lesser or no magnetic field in the entire image. |
