Abstract

A method and an apparatus for checking bank notes, in which data from at least two different measurings of the bank notes to be checked are evaluated. Bank notes are checked, whereby data from at least two different measurings of bank notes to be checked are evaluated, a first property of the bank note to be checked being derived from the data of at least one first measuring, at least one second property of the bank note to be checked being derived from the data of at least one second measuring. A correlation between the first and the second property for the same places on the bank note to be checked is determined, and the first property is derived once again. For the places of the bank note to be checked, for which a correlation between first and at least second property has been determined, an altered derivation of the first property from the data of the at least first measuring is performed.

Method for checking bank notes, in which data from at least two different sensor measurings of the bank notes to be checked are evaluated,

comprising the steps:
deriving a first property of the bank note to be checked from data obtained from at least one first measuring using at least a first sensor,
deriving at least one second property of the bank note to be checked from data obtained from at least one second measuring using at least a second sensor, then
deriving a correlation between said first property and said at least one second property for the same places on the bank note to be checked to provide combined data related to the first and at least one second properties of the bank note to be checked, and then
deriving the first property once again, so that at places on the bank note to be checked, for which said correlation between the first property and the at least one second property was determined, an altered derivation of the first property is effected from the data of the at least first measuring by comparing data obtained from the correlation between the first and at least one second property with the data obtained from the first measuring, and using the result of the comparison to obtain an improved indication of said first property.
