Abstract
A printed media product, such as a trading card, that has a substrate and an encoded data element applied to a surface of the substrate containing information. The encoded data element includes first, second, and third data layers with first, second, and third patterns of encoded, colored dots defined by a binary encoding scheme. The dots of the first, second, and third layers are different colors separately resolvable by a scanner with decoding software. The colors of the dots are cyan, yellow, and magenta, and the layers are printed so that the dots overlap. The binary encoding scheme includes a two dimensional run length limited code. The printed media product includes a graphics element that can be interpreted by a human user, and typically, the information encoded in the encoded data element layers is related to the information in the graphics element.
