Self-POS Fraud Detection via Sensor-Imaging Triggered Problem Image Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-POS systems cannot effectively record fraudulent acts during checkout, particularly in self-service scenarios where commodities are retrieved without being registered.
Innovation Solution
A self-POS system equipped with sensors and an imaging apparatus that detect and record images of commodities retrieved but not registered, utilizing a control unit to capture and store problem images as evidence of potential fraudulent activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a self-POS system is implemented to reduce labor costs, then productivity is improved, but the ability to detect and record fraudulent acts deteriorates
Solution Approach 1:
The patent introduces sensors and imaging apparatuses as intermediary devices between the customer and the commodity shelf. These intermediaries detect commodity retrieval automatically and capture images of suspicious activities, enabling fraud detection without requiring human clerks to monitor each transaction, thus resolving the contradiction between automation and fraud detection capability
Solution Approach 2:
The patent replaces the mechanical monitoring system (human clerks visually observing and manually recording) with an automated sensing and imaging system. Sensors detect commodity retrieval through weight changes or RFID signals, and imaging apparatuses capture images, substituting human mechanical actions with automated technological systems that maintain or improve fraud detection while enhancing productivity
2Device complexity
If no imaging apparatus is installed, then device complexity is reduced, but the ability to record fraudulent acts deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-installing imaging apparatuses and sensors in strategic positions before any fraudulent activity occurs. The system is configured in advance to automatically detect commodity retrieval and capture images, ensuring that fraud evidence is recorded without requiring complex post-event investigation or additional equipment
Solution Approach 2:
The patent uses imaging apparatuses to create visual copies (images) of fraudulent acts as they occur. These image copies serve as evidence records, allowing the system to capture and store fraud information without physically interfering with the transaction process or requiring complex analytical equipment, thus balancing evidence collection with system simplicity

AI summary
A self-POS system (1) according to the present disclosure is a self-POS system whereby a customer registers a commodity and checks out and includes a sensor (2) that detects that the customer has retrieved the commodity in a display state, an imaging apparatus (3) that images the customer, and a control unit (4) connected the sensor (2) and the imaging apparatus (3). The control unit (4) is configured to record, as a problem image, an image including at least an image at the time of the retrieval of the commodity when the commodity detected by the sensor (2) as having been retrieved is not registered. Thus, it is possible to provide a self-POS system, a self-POS terminal apparatus, a control method, and a control program capable of recording a fraudulent act at the time of check-out.
