Abstract
An access authorization system comprising at least one arrangement of a plurality of microparticles and at least one identification unit. The arrangement of the microparticles is affixed to the identification unit. The arrangement of the microparticles forms a forgery-proof identification. A microparticle used in the arrangement has at least one first layer and at least one second layer.
