Decentralized Data Issuance for Portable Cards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for personalizing portable data carriers, such as smart cards, are inflexible and burdensome due to the need for centralized databases and constant communication with various personalization stations, which complicates data conversion and programming.
Innovation Solution
A decentralized system that includes an assignment unit, data server, and multiple production units, where data is prepared in an equipment-independent format and assigned dynamically based on production unit status, allowing for real-time scheduling and flexible access to production resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a centralized system is used to convert data from the issuer based on personalization equipment requirements, then data conversion accuracy is improved, but system complexity and database size increase
Solution Approach 1:
The patent divides the centralized conversion system into individual conversion modules at each personalization station. Each station has its own conversion logic that is locally stored and executed, eliminating the need for a large centralized database while maintaining accurate data conversion for each equipment type.
Solution Approach 2:
Instead of maintaining a single centralized conversion database, the system creates copies of the necessary conversion logic at each personalization station. Each station receives and stores the specific conversion rules needed for its equipment type, allowing independent operation without requiring the entire centralized database.
2Manufacturing precision
If a centralized server controls programming by multiple personalization stations, then programming control accuracy is improved, but communication overhead and system complexity increase
Solution Approach 1:
Each personalization station is equipped with its own conversion module that enables it to independently convert and execute programming commands. The stations no longer require constant communication with a centralized server for conversion operations, as they perform self-service conversion using locally stored equipment-specific logic.
Solution Approach 2:
The conversion logic for each personalization station type is prepared and stored in advance at the station itself, rather than being retrieved from a centralized server during operation. This preliminary preparation eliminates the need for constant communication during programming operations.
3Adaptability or versatility
If data is prepared and assigned dynamically based on production unit status, then system flexibility is improved, but data management complexity increases
Solution Approach 1:
The data management system is segmented into independent units, with each production unit maintaining its own data queue and status information. The assignment unit simply distributes data to available units without managing complex centralized scheduling, reducing overall system complexity while maintaining flexibility.
Solution Approach 2:
The system dynamically assigns data to production units based on their current status (available, busy, error states) without requiring complex centralized management. The dynamic nature of the assignment process is handled by simple status-checking and data distribution mechanisms at the assignment unit.
Data Source
AI summary
A method for managing issuance of a portable data carrier using multiple production units for issuing portable data carriers, a data provisioning unit and an assignment unit. The data provisioning unit receives data for the portable data carrier in a production unit independent format. At least one production unit is assigned to use the data for issuing the portable data carrier in the assignment unit. The data are provided by the data provisioning unit to the assigned production unit and the portable data carrier is issued in the assigned production unit. The data are provided by the data provisioning unit to the assigned production unit in response to a data independent polling for data by the assigned production unit and in the production unit independent format. In the assigned production unit the provided data are converted from the production unit independent format into a production unit dependent format.
