By way of the data detected, the authenticity of each bank note is judged, and in the event that the judgement of the authenticity of the respective bank note leads to the conclusion that a counterfeit and/or counterfeit suspect bank note is present, the data of the respective bank note are transferred to a data bank. ## Claims ### Claim 1 A method for monitoring bank notes for the presence of counterfeit bank notes, comprising the steps of: detecting, by means of a sensor device at each of a plurality of external locations, data of each bank note to be monitored that permit judgement of authenticity of the bank note, and judging the authenticity of the respective bank note at the external locations on the basis of the data detected, characterized in that, in the event that a judgement of the authenticity of the respective bank note leads to a conclusion that at least one of a counterfeit and suspect bank note is present, the data of the respective bank note are transferred from the respective external location to a database disposed at a central location. ### Claim 2 (depends on 1) A method according to claim 1, characterized in that data of the respective counterfeit bank note are stored in the database. ### Claim 3 (depends on 2) A method according to claim 2, characterized in that the data of the respective counterfeit bank notes are compared to data that are already stored in the database. ### Claim 4 (depends on 2) A method according to claim 2, characterized in that data of counterfeit bank notes stored in the database are made available for monitoring bank notes for the presence of counterfeit bank notes. ### Claim 5 (depends on 1) A method according to claim 1, characterized in that the data of the respective counterfeit bank notes are normalized. ### Claim 6 (depends on 1) A method according to claim 1, characterized in that the data of the respective counterfeit bank notes are classified. ### Claim 7 (depends on 1) A method according to claim 1, characterized in that the data of the respective counterfeit bank note are linked with an indication of place permitting conclusions as to the place of appearance of the respective counterfeit bank note. ### Claim 8 (depends on 7) A method according to claim 7, characterized by establishing conformities or similarities of the indication of place and/or the indication of time of the respective bank note with respect to the indications of place and/or time that are already stored in the database. ### Claim 9 (depends on 1) A method according to claim 1, characterized in that the data of the respective counterfeit bank note are linked with an indication of time permitting conclusions as to the time of appearance of the respective counterfeit bank note. ### Claim 10 (depends on 1) A method according to claim 1, characterized in that the processing of the data of counterfeit bank notes is carried out in accordance with a bank note type selected from a group consisting of currency of the bank notes, denomination of the bank notes, and a combination thereof. ### Claim 11 A system for monitoring bank notes for the presence of counterfeit bank notes, comprising: a plurality of external locations each having sensor means for detecting data of each bank note to be monitored that permit judgement of authenticity of the bank note, and a control means for judging the authenticity of the respective bank note on a basis of the data detected, characterized by an interface at each of the plurality of external locations which, under control of said control means, establishes a connection to from the respective external location to a database at a central location, via a communications network in an event that the judgement of the authenticity of the respective bank note by said control means has led to a conclusion that at least one of a counterfeit and suspect bank note is present, and data of the respective bank note are transferred to said database. ### Claim 12 (depends on 11) A system according to claim 11, characterized in that the database stores the data of the respective counterfeit bank note. ### Claim 13 (depends on 12) A system according to claim 12, characterized in that the database is connected to a control unit comparing the data of each counterfeit bank note to data already stored in said database. ### Claim 14 (depends on 12) A system according to claim 12, characterized in that said control unit transfers the data of counterfeit bank notes stored in the database to the control means via the communications network, and in that the control means utilizes the data transferred for monitoring bank notes for presence of counterfeit bank notes. ### Claim 15 (depends on 14) A system according to claim 14, characterized in that the data of said database are stored in said control means. ### Claim 16 (depends on 11) A system according to claim 11, characterized in that said control means links the data of the respective counterfeit bank note with an indication of place. ### Claim 17 (depends on 16) A system according to claim 16, characterized in that said control unit compares indications of at least one of place or time of the respective counterfeit bank note to indications of at least one of place or time stored in said database. ### Claim 18 (depends on 11) A system according to claim 11, characterized in that said control means links the data of the respective counterfeit bank note with an indication of time.
