Abstract
A secure document includes a fluorescent barcode and a fluorescent filler printed onto a substrate. The fluorescent barcode is printed using a first fluorescent ink of a first color and the fluorescent filler is printed using a second fluorescent ink of a second color that is different than the first color. In order to read the fluorescent barcode, the secure document must be illuminated with ultraviolet and/or infrared light. Then, a color filter must be used to filter the fluorescent filler out, leaving the fluorescent barcode visible.
