A sensor for checking value documents, an apparatus with the sensor, and a method for operating the sensor. Neither the software that the sensor executes for checking the value documents nor the adaptation data that the sensor employs for checking the value documents are stored permanently in the sensor itself. The sensor is set up for the software as well as the adaptation data to be loaded into the sensor from outside the sensor. The sensor can be employed for checking value documents only when a data carrier is connected to the sensor, and the data carrier has license data stored thereon through which a license for the employment of the software and/or of the adaptation data is supplied to the sensor.

Sensor for checking value documents

The invention relates to an apparatus and a method for processing value documents. A value document is input to the input opening of an apparatus for value-document processing and transported using a transport system of the apparatus to an image sensor which senses a partial image of the value document. A contour of the front partial area is ascertained from the sensed partial image and checked. If the check of the contour of the front partial area yields a fault, the value document is rejected. Faulty or faultily transported value documents can thus be recognized and transported back to the input opening at a very early time.

Method and device for processing value documents

The invention relates to a method and apparatus for recognizing forged value documents, for example composed forgeries which are assembled from parts of different value documents. In the inventive method, the signal intensity of a measuring signal is determined at a plurality of measuring points on a value document. For one or more selected groups of measuring points which are disposed in particular along certain directions on the value document there are determined gradient values of the signal intensities. The gradient values of a group are subsequently linked to form a connection strength of the group which provides a quantitative statement about the extent to which a large gradient value exists consistently within the particular group. From a relatively great connection strength there can be inferred the presence of a separating line in the area of the selected group of measuring points.

Method and device for testing value documents

The invention relates to an apparatus and a method for automatically checking sheet-shaped documents of value. According to the present invention a simply constructed measuring apparatus can be obtained, by the measuring apparatus evaluating measuring values e.g. at least two measuring frequencies and the position of one or a plurality of discrete measuring tracks being determined in such a way that at least the presence of two different not visible spectral properties of a predetermined type of authentic documents of value can be checked.

Device and method for verifying valuable documents

The invention relates to a method for verifying the origin of bank notes from an automatic teller. In the inventive method for verifying the origin of bank notes, in particular forgeries, from an automatic teller, data characterizing bank notes to be paid out or already paid out from a sensor device for checking the bank notes to be paid out or already paid out for authenticity and/or type and/or state are detected, the data of the bank notes to be paid out or already paid out are stored, check data are generated by means of the sensor device for each bank note whose origin is to be verified, whereby the check data of the bank note to be verified are compared with the stored data of the paid out bank notes and the paid out bank note is ascertained whose stored data have the greatest match to the check data of the bank note to be verified, and the verification of origin for the bank note to be verified from the automatic teller is regarded as furnished if the match exceeds a given threshold value.

Method for identifying banknotes origin

A method for identifying suspected counterfeit and/or counterfeit banknotes paid into an automatic teller machine, wherein banknotes to be paid in are checked for authenticity on the basis of data from a sensor device. The identification is achieved by linking data from the sensor device concerning the suspected counterfeit and/or counterfeit banknotes to an identity of a payer. The method also includes storing the data concerning the suspected counterfeit and/or counterfeit banknotes and the identity of the payer, and generating checking data for the suspected counterfeit and/or counterfeit banknotes by means of the sensor device or a sensor device similar to the sensor device. The checking data are generated by the sensor device for one or more possible positions of the suspected counterfeit and/or counterfeit banknotes, comparing the checking data with the stored data concerning the suspected counterfeit and/or counterfeit banknotes and determining the data of the suspected counterfeit and/or counterfeit banknote which has the closest agreement with the respective checking data. The method further includes identifying the respective suspected counterfeit and/or counterfeit banknote by means of the identity of the payer, which is linked to the data concerning the suspected counterfeit and/or counterfeit banknote with the closest agreement.
