Portable Data Carrier Personalization via Segmented Command Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The personalization phase of portable data carriers is time-consuming and costly, as it involves transmitting and processing both personalization commands and data, with existing methods not efficiently separating user-independent and user-specific data components.
Innovation Solution
The method involves receiving and processing incomplete personalization commands separately from personalization data, with the latter being supplemented to form complete commands, reducing data volume and transmission time by separating user-independent commands for simultaneous writing across multiple data carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If personalization commands and data are transmitted together in the personalization phase, then the data carrier can be personalized, but the transmission time and production time are increased
Solution Approach 1:
The personalization data is segmented into user-independent portions and user-specific portions. The user-independent portion is transmitted separately during the initialization phase, while only the user-specific portion is transmitted during the personalization phase. This segmentation reduces the total transmission time and increases productivity by allowing parallel processing of user-independent data across multiple data carriers.
2Manufacturing precision
If all personalization data is transmitted during the personalization phase, then complete personalization can be achieved, but the data volume to be transmitted is large
Solution Approach 1:
The user-independent portion of the personalization data is extracted from the complete personalization data set and transmitted separately during the initialization phase. This extraction reduces the data volume that needs to be transmitted during the personalization phase, while still achieving complete personalization when the user-specific portion is added later.
3Loss of time
If user-independent personalization data is written separately in advance, then transmission time during personalization is reduced, but the process complexity increases
Solution Approach 1:
The user-independent portion of the personalization data is written in advance during the initialization phase, before the personalization phase begins. This preliminary action reduces the workload and transmission time during the personalization phase. The system manages this complexity through automated state tracking that identifies which data has been pre-written and what remains to be written.
Solution Approach 2:
The system uses feedback mechanisms to track the state of personalization data writing. The data carrier records which portions of personalization data have been written during initialization, and this information is used to guide the personalization phase, ensuring that only the necessary user-specific portions are transmitted and written, thereby managing process complexity efficiently.

AI summary
The method involves receiving incomplete personalization commands (62) in a user-independent manner. Personalization data (64) is received and stored separate from the personalization commands in a user-specific manner, where the personalization data includes both user-specific and user-independent personalization data units. The personalization data are processed to personalize a portable data carrier (10) by supplementing the incomplete personalization commands with the personalization data and running the completed personalization commands. An independent claim is also included for a portable data carrier comprising a processor.
