Purchase Validation Using Product ID and Inventory Database
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cashier-less physical stores face challenges in validating purchases securely due to expensive sensor systems, integration complexities with inventory management, and interoperability issues with payment systems, leading to security concerns and shoplifting risks.
Innovation Solution
A computer-implemented method and system that uses product Identification Details (IDs) embedded in computer-readable codes or tags, updating inventory databases upon payment confirmation, and validating purchases using tracker systems when customers exit the store, enabling or disabling security systems based on valid or invalid purchases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If advanced facial and behavioral recognition security cameras are installed to track customer behavior and prevent theft, then security reliability is improved, but device complexity and implementation cost increase significantly
Solution Approach 1:
The patent extracts the security validation function from complex camera-based tracking systems and implements it through simple product ID scanning at exit points. The system only tracks purchased items via product IDs rather than monitoring all customer movements, thereby achieving security validation with minimal system complexity.
Solution Approach 2:
The patent uses inexpensive product ID tags already attached to products as the tracking medium, rather than installing expensive sophisticated sensor systems. These product IDs serve as disposable, single-use identifiers that are read once at validation points, eliminating the need for expensive reusable infrastructure.
2Reliability
If sophisticated sensor systems are deployed to validate purchases and prevent shoplifting, then security is improved, but implementation cost increases
Solution Approach 1:
The patent makes the product ID system multi-functional by using the same product identifiers for both inventory management and security validation purposes. This universal approach eliminates the need for separate expensive validation systems, as existing product tagging infrastructure serves dual functions.
Solution Approach 2:
The system uses the products' own embedded product IDs for validation rather than requiring external scanning or customer interaction. The product identifiers automatically identify themselves when passed over validation readers at exit points, eliminating the need for customer cooperation or additional service infrastructure.
3Measurement precision
If comprehensive tracking systems are integrated with inventory management systems, then purchase validation accuracy is improved, but system integration complexity increases
Solution Approach 1:
The patent performs preliminary actions by recording purchased product IDs in the inventory system at the moment of purchase. This advance recording ensures that when products are validated at exit points, the system already has the expected product IDs on file, enabling accurate validation without complex real-time integration.
Data Source
AI summary
Embodiments of the present disclosure relates to systems and methods for validating purchase of a product in a physical store. For the validation, a confirmation data for a payment for the product and a product Identification Detail (ID) associated with the product is received upon purchase of the product by a user in a physical store. Upon receiving the confirmation data and the product ID, an inventory database of the physical store is updated with the confirmation data and the product ID for the purchased product. The purchase is validated using the product ID and the updated inventory database when the user is exiting the physical store.
