A method of obtaining a plurality of infrared images of a banknote that involves simultaneously illuminating the banknote with infrared light at a first wavelength and infrared light at a second wavelength, capturing an image of the banknote with an RGB camera, obtaining from both a first output channel signal and a second output channel signal of the RGB camera sensor where the intensity distribution of the infrared light at the first wavelength and the intensity distribution of the infrared light at the second wavelength uses a first calibration coefficient and a second calibration coefficient of the RGB camera sensor, producing separate infrared images of the banknote at the first wavelength and the second wavelength from the respective intensity distributions.

Banknote imaging

A banknote validator having a housing, a validation sensor; and a banknote drive mechanism. The banknote drive mechanism may be arranged to transport a banknote from an input aperture to a stacking device. The banknote drive mechanism may delimit a first banknote pathway proximal to an input aperture, and a second banknote pathway proximal to the stacking device. A pivotable security gate arrangement may be included that is resiliently biased to project into the second banknote pathway.
