Embodiment Construction

[0033] Referring to Figure 1, there is shown a banknote validator housing 10 including a sensing device according to a first embodiment of the present invention. The banknote validator housing 10 includes an upper portion 12 and a lower portion 14 arranged to releasably interlock to form the validator housing 10 . When locked together, the upper and lower parts 12 , 14 define a banknote authentication path which begins at the banknote inlet 16 . For the purposes of the present invention, the banknote housing 10 represents a banknote validator. Even though not all functional parts of the verifier are shown, the key parts of the invention are shown.

[0034] Figure 2 shows the upper and lower parts 12, 14 of the banknote validator housing 10 in a separated position. Here, it can be seen on the components 12 , 14 that the banknote verification path 16 starts at the banknote inlet 16 .

[0035] While it is possible to simply have a single sensing device provided on one side of ...

Abstract

A banknote validation arranged to discriminate between real and false banknotes is described. The valuator comprises: a light source arranged to emit light in the non-visible spectrum onto a banknote being validated, the emitted light including an ultraviolet (lOnm to 400nm) or intra red (800 run - 1 00000nm) wavelength of light; a broadband optical light sensor arranged to sense a relatively broad band of visible light spectrum wavelengths of light emitted by fluorescence from the banknote in response to the banknote being irradiated with the non-visible spectrum wavelengths of light; and an optical filter positioned between the banknote and the sensor and arranged to prevent illumination of the sensor with reflected or transmitted non-fluoresced light from the light source, the optical filter having a -3db cut off point selected such that the light emitted from the light source, having a wavelength closest to the visible light spectrum wavelengths of light, is filtered.

Description

technical field [0001] The present invention relates to improvements relating to banknote authentication and in particular, but not exclusively, to an improved method and apparatus for detecting optical features of banknotes to determine their authenticity. It should be understood that the term "banknote" as used herein should be understood to mean any manufactured article, such as a ticket, certificate or currency note, which is provided and has value on a special paper-like substrate, which substrate has fluorescent characteristics. Background technique [0002] Automatic identification (authentication) of banknotes is well known, (see for example European patent application EP 0738408 by Mars Inc.) and many techniques for distinguishing genuine and counterfeit banknotes are described. Historically, such automated banknote validators have required an array of different types of sensors (and associated radiation sources), where each sensor measures a different physical para...
