ABSTRACT:
A security document is provided comprising human readable transaction data, a plurality of security image elements, a plurality of complementary security image elements, and an encoded information block comprising a plurality of digital glyphs printed thereon. The human readable transaction data printed on the top surface of the substrate forms a full tone image and includes an enhanced security data item. The security image elements printed on the top surface of the substrate and the plurality of complementary security image elements printed on the top surface of the substrate define a security image. The encoded information block comprises a plurality of digital glyphs printed on the top surface of the substrate and comprises encoded transaction data corresponding to at least a portion of the human readable transaction data. The digital glyphs are printed on the top surface of the substrate to form less than a full tone image and the encoded transaction data is positioned proximate the enhanced security data item such that any alteration to the enhanced security data item results in inadvertent alteration to the encoded transaction data.
