| 摘要 |
The invention relates to a smart card (9), in particular a plastic card, having a magnetizable authenticity feature (5) integrated into the smart card, which authenticity feature can be personalized upon irradiation with an energy-rich beam due to the change in physical and/or chemical properties. A magnetic feature is provided in a functional layer (2) as an additional personalizable two-stage feature, said magnetic feature being on the basis of an opto-magnetic process that allows the writing of information, thereby producing magnetism in the irradiated area (5a) which can be macroscopically measured, in particular by microscopic spin coupling of the organometallic compounds that are arranged as complexes and produce magnetism that can be macroscopically measured. Said spin coupling is the result of the supramolecular coupling of the spin of a molecule or molecular structure. |
