Abstract
A separator card substrate material for use in high speed document processing machines is imprinted with an array of periodically laterally spaced magnetic strips across an area of the face of the substrate and furthermore a machine readable code array of light and dark blocks representing selected data is imprinted in at least a portion of the same space of the substrate as is occupied by the magnetic strips with the light and dark blocks spanning widthwise dimensions between the strips as well as lengthwise dimensions between the strips. The interleaving of the magnetic strips and the light and dark blocks enables the separator card to be encoded with relatively large fields of optical data enabling the use of low resolution sensors for detecting the optical data used to uniquely identify each separator card without interfering with the function of the magnetic strips.
