Abstract: A multi-layer card-shaped data carrier has a marking layer containing a hidden marking, and a thermochromic cover layer arranged over the marking layer at least in the area of the hidden marking. The thermochromic cover layer is opaque below its change temperature, hides the marking, and is translucent or transparent above its change temperature, enabling viewing of the marking. The thermochromic cover layer is pervious to radiation outside the visible spectral range and the marking layer absorbs radiation energy outside the visible spectral range, so that the hidden marking can be incorporated into the marking layer through the thermochromic cover layer by laser radiation of a wavelength outside the visible spectral range.

Abstract: The invention relates to an apparatus and a method for checking the usage state of a document of value. The document of value is illuminated with illumination light and with the help of an image sensor there is detected the light intensity of the light reflected from the document of value in order to take an image of the document of value. Of the taken image there is chosen an image detail in which there is imaged an opaque, reflective section of the document of value. The chosen image detail is examined for signs of creases which are possibly present in the opaque, reflective section of the document of value. The results of the examination for creases are used to evaluate the usage state of the document of value.
