Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing money processing devices face challenges in efficiently resolving abnormalities without requiring complex user authentication or manual intervention, which can lead to unauthorized operations and increased operational complexity.
Innovation Solution
A money processing device equipped with a communication circuitry and man-machine interface, generating temporary information and transferring to a state of resolving abnormalities upon receiving corresponding secondary information, ensuring only authorized personnel can perform the operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-configured user IDs and passwords are used for authentication, then security is improved, but device complexity and operational complexity increase
Solution Approach 1:
The system performs preliminary action by generating and storing temporary authentication information in advance of the actual authentication need. When an abnormality occurs, the resolution information is already prepared and can be quickly transmitted to the terminal device without requiring real-time complex authentication processes, thus maintaining security while reducing operational complexity
Solution Approach 2:
The patent extracts the authentication information from the money processing device and transmits it to an external terminal device. This separation allows the money processing device to maintain security through centralized control while the terminal device handles the authentication interface, reducing the operational complexity at the money processing device itself
2Reliability
If pre-configured user IDs and passwords are used for authentication, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The system implements self-service by automatically generating and transmitting resolution information to the terminal device without requiring manual configuration of authentication credentials. The money processing device autonomously manages the authentication process, sending the necessary information to the terminal where it can be automatically validated, thereby improving ease of operation while maintaining security
Solution Approach 2:
By preparing the authentication information in advance and making it available for automatic transmission, the system eliminates the need for operators to manually enter or configure complex authentication details during abnormality resolution, significantly improving ease of operation while preserving security through pre-configured validation rules
3Ease of operation
If temporary information is transmitted to terminal devices, then ease of operation is improved, but risk of unauthorized access increases
Solution Approach 1:
The system applies dynamics by making the authentication information temporary and time-limited rather than static and permanent. The resolution information is generated for specific abnormality events and becomes invalid after use or after a predetermined time period, reducing the window of opportunity for unauthorized access while maintaining ease of operation for legitimate users
Solution Approach 2:
The patent applies local quality by making authentication credentials specific to individual abnormality events and terminal devices rather than using universal credentials. Each resolution information is tailored to a specific context (abnormality type, device state, terminal identity), providing localized security that maintains ease of operation while preventing unauthorized access through context-specific validation

AI summary
A money processing device includes: a money processing unit; a communication circuitry; a man-machine interface; and processing circuitry configured to control the money processing unit, the communication circuitry and the man-machine interface. The processing circuitry generates temporary information, and operates the communication circuitry or the man-machine interface to provide the temporary information to outside. When the communication circuitry or the man-machine interface that is not operated to provide the temporary information to the outside receives secondary information corresponding to the temporary information, the processing circuitry transfers the money processing device to a state of executing a process of resolving an abnormality.
