visible indicia on said product identification side for providing product identification to a viewer of said product identification side;
additional indicia of a first color printed on said product identification side with an ink that will be visible when illuminated with light of a frequency outside of the visible spectrum, said additional indicia being in the form of several discrete marks at less than all of a plurality of predetermined locations on said opposite side to define a selected code word from a family of code words, each code word designating at least one different bit of information;
