Solution Overview

Problem

Prepersonalization data encoding errors in IC chip cards often go undetected until personalization, leading to production disruptions for card issuers.

Innovation Solution

A method involving separate transport keys for unlocking and encoding data storage containers in IC chip modules, allowing for prepersonalization data verification and correction before personalization, using a software module to test and correct discrepancies, and providing a system for secure key management and data encoding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If prepersonalization data encoding is completed by a service provider prior to delivery, then productivity is improved, but reliability deteriorates due to undetected encoding errors

Engineering Contradiction:

Improvecard production efficiencyVSAvoiddata encoding accuracy

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent implements preliminary testing of prepersonalization data encoding by having the card issuer or designee test a sample of encoded cards before full personalization. This allows encoding errors to be detected and corrected in advance, resolving the contradiction between improved productivity through prepersonalization and maintained reliability through early error detection.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent establishes a feedback mechanism where the card issuer or designee tests encoded cards and provides feedback on encoding accuracy. This feedback loop enables correction of encoding errors before final personalization, maintaining reliability while preserving the productivity benefits of prepersonalization encoding.

Inventive Principle:

Principle #23Feedback

2Reliability

If separate transport keys are used for unlocking and encoding, then reliability is improved through secure key management, but device complexity increases

Engineering Contradiction:

Improvesecure data encodingVSAvoidkey management system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the key management function into separate transport keys for unlocking and encoding operations. This segmentation improves security by preventing a single key compromise from affecting both operations, while the modular structure actually reduces overall system complexity by making each key's purpose clear and manageable.

Inventive Principle:

Principle #1Segmentation

AI summary

A method and system are disclosed for providing integrated circuit chip cards (e.g. transaction cards) pursuant to an order placed by or on behalf of a card issuer wherein a testing data file is provided in conjunction with prepersonalization data encoding for use in conjunction with subsequent testing of the accuracy of the encoded prepersonalization data. Such testing may be completed prior to personalization data encoding to facilitate the identification of prepersonalization data encoding errors, thereby further facilitating remedial action and reduction of production disruptions.
