Abstract
A system and method for obtaining a full image of a bank note being processed. An array of magnetoresistive detectors is employed to obtain multiple line-scan sensings of a bank note as the note passes. A central processing unit obtains the plurality of sensings as magnetic pattern data which is subsequently stored in a database for later processing.
Claims16
A system for automatically detecting the magnetic features of a bank note, the system comprising:
- a transport device capable of transporting a bank note along a defined path;
- a data processing device capable of executing stored program instructions;
- a data storage device operably coupled with the data processing device;
- and
- a first detector device operably coupled with the data processing device, the first detector device comprising a plurality of magnetoresistive sensors positioned proximate the transport device and oriented so as to enable detection of the magnetic features of the adjacent surface of the passing bank note;
- wherein the data processing device is capable of executing stored program instructions for detecting the magnetic features of a bank note, the program instructions comprising:
- repeatedly reading the output of the first detector device to capture the magnetic pattern data of the adjacent surface of the passing bank note;
- storing the captured magnetic pattern data in the data storage device;
- and
- making a determination regarding final processing of the bank note based upon the magnetic pattern data.

A method for detecting the magnetic features of a bank note, the method steps comprising:
- transporting the bank note along a defined transport path proximate to a first array of magnetoresistive detectors;
- repeatedly reading the outputs from the first array of magnetoresistive detectors as the note is adjacent thereto to obtain first surface magnetic pattern data of the surface of the passing note adjacent to the detector array;
- analyzing the first surface magnetic pattern data with a data processing device;
- and
- making a determination regarding final processing of the bank note based upon the first surface magnetic pattern data.
