Point of Sale Product Identifier Validation System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retailers incur significant revenue losses due to customers switching product identifiers, such as barcode labels, to obtain expensive items at a lower price, exploiting advancements in home printer technology and software to create counterfeit labels that can be scanned and read by point-of-sale systems.
Innovation Solution
A method and system that validate the authenticity of product identifiers like UPC, EAN, JAN, and RFID codes in real-time during transactions by comparing entered identifiers against a database of suspect or counterfeit items, allowing transactions only if they match records, and denying them if discrepancies are found, with optional multiple validation layers for higher-priced items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If barcode labels are made easier to reproduce and switch, then ease of operation improves, but loss of substance worsens due to fraudulent transactions
Solution Approach 1:
The system performs preliminary validation by checking the barcode against a database of known counterfeit codes before completing the transaction. This preemptive measure identifies fraudulent attempts before they can result in revenue loss, while still allowing legitimate transactions to proceed smoothly.
Solution Approach 2:
A validation system acts as an intermediary between the barcode scanner and the point-of-sale transaction. This intermediary layer verifies the authenticity of the barcode by comparing it against a database of suspect codes, blocking fraudulent transactions while permitting legitimate ones.
2Reliability
If barcode validation is implemented, then reliability improves by preventing fraud, but device complexity worsens
Solution Approach 1:
The validation system is designed to work with multiple types of product identifiers including UPC, EAN, JAN, and RFID codes through a single unified interface. The system performs the same validation logic across different identifier types, reducing the need for separate validation mechanisms for each code type.
Solution Approach 2:
The system uses a database of copied or replicated counterfeit barcode codes to identify fraud. By maintaining a repository of known suspect codes, the system can quickly compare incoming barcodes against this reference data to detect switching attempts without requiring complex analysis of each individual code.
3Reliability
If multiple validation layers are applied to high-value items, then reliability improves, but productivity worsens due to additional verification steps
Solution Approach 1:
The system applies different levels of validation intensity based on the specific characteristics of each transaction. High-value items or those with suspicious barcodes receive more stringent multi-layer validation, while standard low-risk transactions proceed through a streamlined validation process, optimizing both security and throughput.
Solution Approach 2:
The validation system dynamically adjusts its checking parameters based on the transaction context. For high-value items, the system activates additional validation layers including multiple database queries and cross-referencing. For standard transactions, a single quick check suffices, maintaining fast processing speeds while providing enhanced security when needed.
Data Source
AI summary
The invention provides a process/system that validates the authenticity of the product UPC, EAN, JAN, RFID, EPC and/or equivalent code, in real-time, while a transaction is taking place. A database is preferably maintained including a list of suspected false or counterfeit UPC, EAN, JAN, RFID, EPC, and/or equivalent number or first digits, and further includes a list of key descriptive text or numbers found on a product or a product's packaging that will either corroborate or contradict the real brand name with the brand encoded in the UPC, EAN, JAN, RFID EPC, and/or equivalent number. The invention allows a transaction if the item is not found in the database of suspect or counterfeit items, or if all of the identifiers match a record in the database; otherwise, the transaction is denied.
