Abstract
A method and a machine are disclosed, for checking a banknote to determine its genuineness, wherein light-sensitive elements scan a few read out points on a banknote and amplifies the signals so produced up to a normalized maximum, the machine then computing the average of all the normalized read out values and detecting the deviation relative to said average, and finally checking that such errors or deviation from the average lie within preselected calibration ranges which are predetermined on a statistically significant number of genuine banknotes.
