Thermal paper with a near infrared radiation scannable data image
 Thermal paper having a near infrared radiation scannable data image comprised of near infrared flourescent compounds provides scannable data invisible to the naked eye with little interference from printed text or images on the thermal paper. The near infrared fluorescent pigments are protected from contact with oxygen using a polymer resin. Thermal papers with overlapping bar codes can be prepared when using two or more near infrared radiation scannable bar codes that respond to different wavelengths. The overlapping bar codes provide more information in a given area.
