Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Card issuing systems experience high misread rates due to vision camera inaccuracies and limited memory in user devices, leading to decreased performance and security vulnerabilities.
Innovation Solution
A card generating system utilizing a card information database and a vision system to process two-dimensional barcodes, which selects and verifies cards based on requests, reducing manual interventions and enhancing security by minimizing stored information on user devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If vision cameras are used to read card information, then card issuing automation is improved, but misread rate increases due to camera inaccuracies
Solution Approach 1:
The patent introduces an intermediary verification process where a second vision camera captures images of the issued card to verify the printed information matches the original request. This intermediary check acts as a mediator between the initial card issuance and the final verification, resolving the contradiction by adding a validation layer that catches misreads without reducing automation.
Solution Approach 2:
The system implements feedback by comparing the originally requested card information with the actual printed card information through a second vision camera. This feedback loop identifies discrepancies between intended and actual card outputs, allowing the system to detect and correct errors that occurred during the automated issuance process.
2Adaptability or versatility
If user devices store all card information for troubleshooting, then diagnostic capability is improved, but security vulnerability increases
Solution Approach 1:
The patent extracts only the necessary card information needed for troubleshooting and stores it securely in a database rather than storing all card information on user devices. This extraction approach provides diagnostic capability with minimal data, reducing security vulnerabilities by limiting the amount of sensitive information stored on potentially compromised devices.
Solution Approach 2:
The system uses a database as an intermediary between the card issuing system and troubleshooting processes. Instead of storing information directly on user devices, the database serves as a secure mediator that provides necessary diagnostic information while maintaining security controls and access restrictions.

AI summary
A card generating system that includes a card information database and a card processing system. The card processing system comprises an interface, a vision system, a processor, and card processing hardware. The interface is configured to receive card requests. The vision system is configured to process two-dimensional barcodes to obtain card feature data. The processor is operably coupled to the interface, the vision system, and card processing hardware. The processor is configured to select a card comprising a two-dimensional barcode based on the card request and to obtain a card data file corresponding with the card request. The processor is further configured to compare card feature data to the card data file and to determine whether the card feature data corresponds with the card data file. The card processing hardware is configured to process the card in response a determining the card feature data corresponds with the card data file.
