Camera-Based Transaction Tracking for Walk-Away Theft Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-service checkout systems fail to effectively prevent 'walk-away theft' where consumers properly scan items but exit the store without paying, especially during high traffic periods when attendants are overwhelmed.
Innovation Solution
A system and method for person transaction tracking using cameras to monitor the movement of customers, items, bags, and carts relative to a transaction terminal, raising alerts when payment is not received before movement away from the terminal, and integrating with staff and security systems to address potential theft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If SSTs are placed at store exits to enable quick checkout, then consumer convenience and checkout speed are improved, but the ability to detect and prevent walk-away theft deteriorates because consumers are already close to exiting
Solution Approach 1:
The system performs preliminary tracking and detection of consumer movement patterns before the consumer actually exits the store. Cameras and sensors monitor the consumer from the SST through the exit path, enabling early detection of walk-away theft attempts before the consumer leaves the premises.
Solution Approach 2:
The patent introduces an intermediary monitoring system consisting of cameras, sensors, and alert mechanisms between the SST and the store exit. This intermediary system provides an additional layer of detection and notification, allowing staff to intervene before the consumer completely exits the store.
2Reliability
If SST attendants monitor all terminals to prevent theft, then theft prevention reliability is improved, but device complexity and staffing requirements worsen
Solution Approach 1:
The system enables self-monitoring through automated camera systems, motion sensors, and alert mechanisms that automatically detect and report suspicious behavior without requiring constant human supervision. The technology performs the monitoring function autonomously, reducing the burden on attendants.
Solution Approach 2:
The patent replaces manual monitoring by attendants with an automated electronic monitoring system using cameras, sensors, and computer vision algorithms. This substitution reduces human labor requirements while maintaining or improving detection reliability.
3Measurement precision
If manual monitoring of all SSTs is implemented, then detection precision for theft is improved, but productivity and response time worsen during high traffic periods
Solution Approach 1:
The system implements real-time feedback through immediate alerts to staff when walk-away theft is detected. The automated system continuously monitors and provides instant notifications, enabling rapid response without requiring manual inspection of each terminal.
Solution Approach 2:
The patent replaces slow manual monitoring with fast automated electronic detection systems that can process multiple terminals simultaneously and provide immediate alerts, significantly improving response time during high-traffic periods.
Data Source
AI summary
Images are captured of a customer during a transaction at a transaction terminal along with images associated with items of the transaction and any bags or cart used to hold the items. The images are processed to track any movement and locations of the customer, items, bags, and cart relative to a known location of the transaction terminal. When a transaction payment is required for the transaction and movement is detected in a direction that is moving away from the transaction terminal before a payment notification is received for the transaction, one or more alerts are raised as an indication to staff and/or security systems of a potential in-progress walk-away theft.
