A print medium having a sense mark comprised of a near infrared fluorescent component which triggers automated operations without interference from printed text or images or the substrate. The near infrared fluorescent pigments are protected from contact with oxygen using a polymer resin. Apparatus for dispensing printed media comprises a print medium of this invention, detector for sensing the mark, a logic element for locating the mark and a paper transporting apparatus controlled by the logic element. The apparatus can be incorporated in business machines such as automatic teller machines, cash registers, ticket dispensing machines and coupon dispensing machines.

[ What is claimed is:] [1.] A medium for printing which comprises a base sheet and at least one mark on the surface of said base sheet positioned to trigger an automatic operation when identified by a logic element, said mark comprising:a) a near infrared-fluorescence (NIRF) compound which reflects near infrared radiation when illuminated with near infrared radiation, the concentration of said NIRF compound in said mark is sufficient to increase the reflectance of near infrared radiation of said mark above that of said base sheet; andb) a polymer resin which limits contact of the NIRF compound with air, wherein said mark is transparent or invisible to the naked eye and the contrast in reflecting near infrared radiation between said mark and said base sheet are sufficient such that the mark can be sensed by a detector operating in the near infrared region of 670 nm to 2500 nm and the location of the mark can be identified by a logic element by one or more signals from the detector.
