Abstract:
A blur resistant barcode is disclosed. The blur resistant barcode comprise a plurality of parallel lines and spaces where information is encoded in the barcode by variations in the thicknesses of the plurality of parallel lines and by variations in the spacing between the plurality of parallel lines. The blur resistant barcode has at least one blur resistant feature that has a thickness in an axis of motion greater than a maximum thickness of any one of the plurality of parallel lines. The axis of motion is perpendicular to the plurality of parallel lines.
