Bill Processing Device Serial Number Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bill processing devices lack the accuracy in determining the authenticity of bills, particularly in matching serial number information, which affects the efficiency and reliability of counterfeit detection.
Innovation Solution
A bill processing device is designed with a loading unit, reading unit, determining unit, stacking unit, and reject unit, where the determining unit compares serial number information and determines if it matches, with the option to set predetermined partial common sections for easier matching and the ability to handle unreadable bills by capturing and composing image data for operator input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the determining unit compares the entire serial number information, then the accuracy of authenticity determination is improved, but the determination process time increases
Solution Approach 1:
The patent divides the serial number comparison into segments: first comparing predetermined partial common sections (which are identical in genuine bills), then comparing the remaining portions. This segmentation allows the system to quickly eliminate counterfeit bills through partial matching while maintaining overall accuracy, thus resolving the contradiction between thorough verification and processing speed.
2Reliability
If the device reads and compares complete serial number information, then the reliability of counterfeit detection is improved, but the complexity of the reading and processing system increases
Solution Approach 1:
The patent extracts and prioritizes the comparison of predetermined partial common sections from the complete serial number verification process. By focusing first on these essential matching portions, the system achieves reliable counterfeit detection without requiring equally complex processing for the entire serial number, thus reducing overall system complexity while maintaining reliability.
3Productivity
If the device automatically reads serial number information, then the productivity is improved, but the ability to handle unreadable bills decreases
Solution Approach 1:
The patent introduces an intermediary manual input mechanism that bridges automatic reading and final verification. When automatic reading fails or produces unreadable results, operators can manually input serial number information, which is then verified against the predetermined partial common sections. This intermediary approach maintains high automated processing speed while preserving the ability to handle unreadable or damaged bills.

AI summary
A bill processing device includes: a loading unit that feeds a bill having a pair of serial number information; a reading unit that reads the pair of serial number information from the fed bill; a determining unit that determines whether at least a portion of the pair of serial numbers match each other; a stacking unit that stacks the bill in a case where the determining unit has determined that the at least a portion of the pair of serial numbers match each other; and a reject unit that receives the bill in a case where the determining unit has determined that the at least a portion of the pair of serial numbers do not match each other.
