http://www.freepatentsonline.com/y2014/0098360.html

United States Patent Application 20140098360

A method of discriminating a banknote using terahertz waves includes irradiating a banknote with terahertz waves; detecting reflected waves reflected from the banknote; generating a reflected image of the banknote based on the detected reflected waves; and discriminating the banknote based on the reflected image. Accordingly, whether a banknote is genuine or counterfeit, and the denomination of the banknote, may be easily and correctly determined using the reflected waves or transmitted waves passing through the banknote.
