Abstract
Abstract A method of manufacturing documents such as paper money, credit cards, identification cards and the like in a manner so as to prevent forgeries thereof, comprises the steps of producing a base material, coating fibers with a magnetic or magnetizable material, and embedding the fibers into the base material during the production of the base material; an apparatus for checking the authenticity of documents such as paper money, credit cards, identification cards, and the like comprises in combination a document having fibers which are coated with a magnetic or magnetizable material embedded therein, detecting means for scanning the document to determine the number of magnetic particles present in the document, and means for moving the document and the detecting means relative to each other so as to provide a scanning trace, the document and the detecting means being disposed in a close relationship to each other.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
119 words
An apparatus for checking the authenticity of documents such as paper money, credit cards, identification cards, and the like, said apparatus comprising in combination: a document having fibers which are coated with spaced magnetic or magnetizable particles embedded therein; detecting means for scanning said documents to determine the number of particles present in said documents; and means for moving said document and said detecting means relative to each other so as to provide a scanning trace, said document and said detecting means being disposed in a close relationship to each other, wherein said detecting means comprises a scanner having a rotational movement and said document is provided with a translational movement so as to obtain a circular scanning trace.
Claim 2
Independent Claim
119 words
An apparatus for checking the authenticity of documents such as paper money, credit cards, identification cards, and the like, said apparatus comprising in combination: a document having fibers which are coated with spaced magnetic or magnetizable particles embedded therein; detecting means for scanning said documents to determine the number of particles present in said documents; and means for moving said document and said detecting means relative to each other so as to provide a scanning trace, said document and said detecting means being disposed in a close relationship to each other, wherein said detecting means comprises a scanner having a rotational movement and said document is provided with a translational movement so as to obtain a circular scanning trace.
Claim 3
Dependent Claim
29 words
An apparatus as claimed in claim 1, wherein the linear speed of the rotational movement of said scanner is higher than that of the translational movement of said document.
Claim 4
Independent Claim
125 words
An apparatus for checking the authenticity of documents such as paper money, credit cards, identification cards, and the like, said apparatus comprising in combination: a document having fibers which are coated with spaced magnetic or magnetizable particles embedded therein; detecting means for scanning said documents to determine the number of particles present in said documents; and means for moving said document and said detecting means relative to each other so as to provide a scanning trace, said document and said detecting means being disposed in a close relationship to each other, wherein said detecting means comprises a scanner which has an overlapping rotational movement and a translational movement which is continuously increasing away from its rotational center so as to provide a spiral-shaped scanning trace
Claim 5
Independent Claim
125 words
An apparatus for checking the authenticity of documents such as paper money, credit cards, identification cards, and the like, said apparatus comprising in combination: a document having fibers which are coated with spaced magnetic or magnetizable particles embedded therein; detecting means for scanning said documents to determine the number of particles present in said documents; and means for moving said document and said detecting means relative to each other so as to provide a scanning trace, said document and said detecting means being disposed in a close relationship to each other, wherein said detecting means comprises a scanner which has an overlapping rotational movement and a translational movement which is continuously increasing away from its rotational center so as to provide a spiral-shaped scanning trace
Claim 6
Independent Claim
132 words
An apparatus for checking the authenticity of documents such as paper money, credit cards, identification cards, and the like, said apparatus comprising in combination: a document having fibers which are coated with spaced magnetic or magnetizable particles embedded therein; detecting means for scanning said documents to determine the number of particles present in said documents; and means for moving said document and said detecting means relative to each other so as to provide a scanning trace, said document and said detecting means being disposed in a close relationship to each other, wherein said detecting means comprises a plurality of single scanners which rotate with varying radii, measuring areas of equal dimensions, are obtained by a computer which translates the count-summaries, which are scanned from the various measuring areas, to a norm-measuring area.
Claim 7
Independent Claim
