A system and method for automatically detecting the presence of a perforation, tear, or a transparent window security feature in a bank note. The system includes an optical detection device, and an ultrasonic detection device, and a conveyance device for transporting the bank note along a defined path proximate the detection devices. Each detection device comprises a plurality of optical transmitters and corresponding optical receivers that bracket the note path. A computing device is also provided to determine from the output of the optical detection device the presence of an optical abnormality in the bank note; to determine from the output of the ultrasonic detection device the presence of an ultrasonic abnormality in the bank note; and to determine the presence of a perforation, tear, or transparent window feature based upon the results of the optical abnormality determination or the ultrasonic abnormality determination.
A system for automatically detecting the presence of a transparent window security feature in a bank note, the system comprising:
A method for automatically identifying the presence of a transparent window security feature in a bank note, the method steps comprising:
A computer software program tangibly embodied in a computer readable medium, the program including machine-readable instructions executable by a computer processor for performing a method for automatically detecting the presence of a transparent window security feature in a bank note being processed by a currency processing machine that utilizes an optical detection device and an ultrasonic detection device to sense the bank note as it advances along a defined path, the program steps comprising:
