Checkout System Movement Detection for Loss Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In some checkout systems, products are carried out of the store without completing the checkout process when the product registration device and checkout device are at different locations, leading to potential losses.
Innovation Solution
A checkout system that includes a product registration device, a checkout device, and an output mechanism to inform of any movement of products, shopping baskets, or shopping carts based on the checkout process state, preventing unauthorized removal by alerting staff when items are taken before the process is completed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the product registration device and checkout device are provided at mutually different positions, then the checkout process can be conducted separately from product registration, but customers may take out products without completing the checkout process
Solution Approach 1:
The system continuously monitors the checkout process state and provides feedback through notifications to both customers and staff. When a product is registered but not yet checked out, the system generates alert notifications that are displayed on screens and can be sent to mobile devices, ensuring that incomplete transactions are detected and addressed promptly.
Solution Approach 2:
The system introduces an intermediary monitoring mechanism that tracks the relationship between product registration and checkout completion. This intermediary function correlates registered products with completed checkouts and generates alerts when discrepancies are detected, acting as a bridge between the registration and checkout processes.
2Reliability
If the system monitors all products to detect unauthorized removal, then product security is improved, but system complexity increases
Solution Approach 1:
The system extracts only the essential monitoring function from a comprehensive surveillance system. Instead of implementing complex image recognition and tracking of all products, it focuses specifically on detecting whether registered products have been properly checked out by comparing registration data with checkout completion data, simplifying the monitoring approach while maintaining security.
Solution Approach 2:
The system uses data copying and correlation rather than physical product tracking. It creates a digital record of registered products and checks out products by comparing this copy with actual checkout transactions, avoiding the need for complex physical monitoring mechanisms while maintaining accurate tracking.
3Reliability
If the system provides real-time notifications for incomplete checkouts, then loss prevention is improved, but information processing requirements increase
Solution Approach 1:
The system performs preliminary data preparation by maintaining an updated list of registered but not yet checked out products. This preliminary organization of information allows for efficient real-time notification generation without requiring complex on-the-spot data processing, as the monitoring data is already structured and ready for comparison.

AI summary
The present invention addresses the problem of preventing products from being carried outside a store without complete a checkout process in a checkout system in which a product, a shopping basket in which the product is accommodated, or a shopping cart in which the product is accommodated is disposed in a checkout device when performing a checkout process. In order to solve the problem, a product registration device (10) registers the product. The checkout device (20) performs the checkout process for the product registered by the product registration device (10). An output unit (320) outputs information indicating that a target object (30) (in the example shown in the drawing, a shopping cart (32) in which a product is accommodated) has moved from the checkout device (20) on the basis of the presence or absence of movement of the target object (30) from the checkout device (20), and the state of the checkout process.
