Abstract

An apparatus for recognizing identifications elements provided on moving carriers includes a reader having a reading head and an evaluating or analyzing logic. The carrier which is advanced past the reading head is provided with at least one identification field including a pattern of marks which are made of phosphorescent substance. By being exposed to light emitted from a light source, the identification marks phosphoresce and are read by the reading head after the exposure has taken place.
