Toners containing encapsulated crystalline resin have lower minimum fix temperatures without charge degradation. In some embodiments, the first layer is an aluminum layer and the second layer is a nickel layer. The gear arrangement is provided with a slide-rod for each readingwriting unit, the slide-rod being embodied in the form of a toothed rack being able to be displaced in the direction of movement of the chip card. The inverter system also comprises a second inverter coupled to the second energy source and adapted to drive the electric motor, wherein the second set of windings are coupled to the second inverter.
