#CMT# #/CMT# The smart card (1) has a chip (2) and a security feature (3), which is formed as an organic photodiode or LED that is sensitive for an organic magneto-resistive effect, or as a transistor that is sensitive for the effect. The feature causes a change of an illuminating intensity of the LED or photodiode based on an application of a temporally or spatially changing magnetic field. The feature causes a change of a magnetic field of the LED or photodiode based on an application of temporally or spatially changing illumination. A detector (4) is sensitive for signals produced by the feature. #CMT#USE : #/CMT# Contact type/ contactless smart card for carrying out electronic money transfer. #CMT#ADVANTAGE : #/CMT# The security feature is formed as the organic photodiode or organic LED that is sensitive for the organic magneto-resistive effect, or as the transistor that is sensitive for the magneto-resistive effect, so that the smart card can be protected against forgery in an improved manner with a reduced technical and equipment expenditure. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a safety system with a smart card and a detector for the smart card. 1 : Smart card 2 : Chip 3 : Security feature 4 : Detector. |
