Abstract
A product surface including a first optoelectronically readable code formed by an arrangement of planar cells of a first and a second cell type. The code has a large detectable region and the readability thereof is robust in relation to demands during the production and/or the use of the surface. The cells, as integral components of the surface, have a surface profile. An intensity difference ΔI=I−Iin the intensity Ireflected by the surface profile of the second cell type and intensity Ireflected by the surface profile of the first cell type results in the case of light incidence as a result of the configuration of the surface profiles. The surface has a second code. The maximum of the absolute intensity difference |ΔI| of the first code lies in a different reflection direction than the maximum of the absolute intensity difference |ΔI| of the second code.
