    摘要: A method and apparatus for identifying a document (55). The method comprises exposing the document (55), such as a banknote, to infrared radiation; detecting infrared radiation reflected from a plurality of regions of the document (55) to generate at least one test pattern; determining if the or each test pattern satisfies a predetermined relationship with a predetermined pattern or patterns corresponding to a known document; and, if the predetermined relationship is satisfied, identifying the document (55) as being the same as the known document.
