Transaction Registration System with Settlement Redirection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In semi-self-service transaction processing systems, settlement delays occur when a settlement apparatus cannot receive transmission of settlement information from an input processing apparatus, particularly if the master machine is unavailable due to breakdowns, leading to inefficiencies and potential customer frustration.
Innovation Solution
A transaction processing system with a registration machine that generates and transmits settlement information to multiple settlement devices via a network, records transaction specifying information on a medium if transmission to the first settlement device fails, and stores the information in a storage unit, allowing the second settlement device to process the transaction if the first is unavailable, ensuring continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the master machine is used as the primary settlement device, then settlement processing can be centralized and managed efficiently, but the system becomes vulnerable to breakdowns and single points of failure
Solution Approach 1:
The patent introduces a transaction specifying information medium (barcode receipt) as an intermediary carrier that bridges the gap between the registration machine and alternative settlement devices. When the master machine is unavailable, this intermediary enables the satellite machine to retrieve and process settlement information independently, resolving the single point of failure issue while maintaining centralized management architecture
Solution Approach 2:
The system performs preliminary action by pre-generating and distributing transaction specifying information to customers at the time of registration. This allows customers to present the information to alternative settlement devices if the primary master machine is unavailable, ensuring continuous operation without requiring real-time system availability
2Device complexity
If settlement information is transmitted only to the master machine, then data flow is simplified and centralized, but transmission failures due to master machine breakdowns cause complete settlement interruption
Solution Approach 1:
The patent segments the settlement information into two parts: transaction specifying information (distributed to customer via barcode) and detailed settlement data (stored on server). This segmentation allows the satellite machine to function with minimal information from the barcode while detailed processing occurs on the server, enabling settlement continuity even when the master machine is unavailable
3Reliability
If multiple settlement devices are deployed, then settlement capacity and redundancy are improved, but the system complexity and coordination requirements increase
Solution Approach 1:
The patent inverts the traditional hierarchy by allowing the satellite machine to independently process settlements using barcode information without requiring active coordination with the master machine. The master-satellite relationship becomes passive-active during failures, simplifying real-time coordination while maintaining multiple operational devices for redundancy

AI summary
According to one embodiment, a registration device for a transaction processing system includes a communication interface connected to a plurality of settlement devices via a network. The plurality of settlement devices includes a first settlement device and a second settlement device. A processor of the registration device is configured to generate settlement information required for settlement of a merchandise transaction based on the registration of items in the merchandise transaction, and then transmit the settlement information to the first settlement device. If the transmission of the settlement information to the first settlement device fails, the processor records transaction specifying information on a medium that can be given to a customer. The transaction specifying information identifies the settlement information corresponding to the merchandise transaction. The processor also store the settlement information in a storage unit when the transmission to the first settlement device fails.
