Abstract (en)
[origin: EP3133562A1] An object is to realize a stricter authentication of a banknote while reducing the cost by making a sensor structure simpler. An excitation light is irradiated on a banknote having a characteristic to emit phosphorescence when irradiated with the excitation light, and a transmitted light passing through the banknote and an afterglow of the phosphorescence emitted by the banknote are detected with a line sensor (120). Authentication of the banknote is determined by evaluating the similarity between each of light-on image data (132) acquired while the excitation light is being irradiated, afterglow-intensity image data (134) generated from an afterglow intensity after the excitation light is turned off, and afterglow decay-rate image data (135) generated from a decay rate of the afterglow intensity after the excitation light is turned off, and a light-on reference image, an afterglow-intensity reference image, and an afterglow decay-rate reference image corresponding to a genuine banknote and stored previously.
