Abstract
Disclosed is a method of embedding machine readable information on a substrate, including converting the information to machine readable code format and writing the machine readable code format on the substrate with at least one fluorescent marking material. Also disclosed is a system for embedding and recovering machine readable information on a substrate, including an image forming device containing at least one fluorescent marking material, wherein the image forming device receives data representative of the machine readable information, and forms an image corresponding to the data in a machine readable code format with the at least one fluorescent marking material on an image receiving substrate, and a document reading device including a radiation emitting unit that emits radiation effecting fluorescence of the at least one fluorescent marking material, and a reader that detects the data in the image on the image receiving substrate while the at least one fluorescent marking material is fluorescing.
