Abstract: Information is recorded in quick response codes. A hologram is made from quick response codes and provides three dimensions of information in a two-dimensional hologram. The holograms are used for recording large amounts of information in two dimensions. Multiple quick response codes containing copious information are created using different light wave frequencies in different quick response encoders. The multiple quick response codes are combined in a two-dimensional hologram that is used on labeling. The hologram is read by a hologram reader. Each quick response frequency layer is separated from the hologram. The quick response code is extracted from each layer. A quick response reader provides the information that has been recorded.
