Banknote Processing Device Verification via Data Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In banknote processing devices, it is difficult to confirm whether banknotes returned to customers are the actual ones deposited, especially in direct deposit systems where banknotes are not temporarily held, making it challenging to ensure accurate return verification.
Innovation Solution
A banknote processing device with a deposit aperture, verification section, storage section, and conveyance control system that compares characteristic information of banknotes at the time of deposit and return, allowing for ejection of mismatched banknotes and temporary holding or general-purpose storage for verification, ensuring accurate return confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If banknotes are conveyed directly to banknote cassettes without temporary holding, then cash processing time is shortened, but it becomes difficult to verify that returned banknotes are the actual deposited ones
Solution Approach 1:
The system performs preliminary identification and recording of banknote characteristic information (such as serial numbers) at the time of deposit, before the banknotes are conveyed to the storage section. This preliminary action enables later verification during the return process without requiring temporary holding of the banknotes.
Solution Approach 2:
Instead of physically holding and comparing the actual banknotes, the system creates and compares copies of characteristic information (identification data) from the banknotes. The identification unit captures characteristic information during deposit, and this recorded information is later compared with information captured during return to verify authenticity.
2Measurement precision
If banknote verification is performed by comparing characteristic information at deposit and return, then verification accuracy is improved, but device complexity increases
Solution Approach 1:
The identification unit serves multiple functions: it identifies banknotes during deposit, records their characteristic information, and enables verification during return. The conveyance control unit also performs multiple functions by controlling both the deposit conveyance to the storage section and the return conveyance from the storage section, reducing the need for separate dedicated components.
Solution Approach 2:
The system uses feedback by comparing the characteristic information captured during return with the information recorded during deposit. The comparison unit provides feedback on whether the returned banknotes match the originally deposited ones, enabling verification without requiring complex physical handling mechanisms.

AI summary
A currency note processing device has a deposit opening. A currency note recognition section recognizes unique information of a deposited currency. A currency note storage section accumulates the deposited currency notes. A transportation control section controls the transportation of the deposited currency note such that the currency note is transported directly to the currency note storage section, and when a return instruction for the deposited currency note is detected, controls the transportation of the deposited currency note from the currency note storage section to the currency note recognition section. A comparison section compares the unique information recognized at the time of the first transportation, from the deposit opening to the currency note recognition section, is compared to unique information recognized at the time of the second transportation, from the currency note storage section to the currency note recognition section.
