Abstract: An identification card, which has an increased safeguard against counterfeiting, comprises both a hologram containing information and information which is visible recorded in a single layer of recording material disposed on a substrate. The card is produced by first recording the visible information on a layer and then recording a hologram in a portion of the layer. Since the hologram may include both the visible information of the card and information which is coded to be read only by a machine, the process for evaluating the hologram converts the reconstructed hologram into electrical signals by means of a vidicon. Then the signals, which correspond to the machine-readable coded information, are separated from the other signals and processed separately.
