Card Management System Delegate Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current payment card systems lack the ability for cardholders to create and manage primary/dependent relationships independently of the card issuer, limiting flexibility and control in card usage and management.
Innovation Solution
A card management system that allows cardholders to register and delegate access to others, enabling primary users to grant full or restricted access to dependent users, who can then manage and view card details, set preferences, and perform transactions without the card issuer's knowledge or involvement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cardholders use traditional payment card systems with card issuer validation, then transaction security and issuer control are maintained, but cardholder flexibility and independence in managing card access are limited
Solution Approach 1:
The patent introduces a card management system as an intermediary layer between the cardholder and the card issuer. This mediator enables cardholders to create primary/dependent relationships and manage card access independently without requiring direct involvement from the card issuer, thus improving flexibility while maintaining system security through the issuer's existing validation infrastructure.
Solution Approach 2:
The patent segments card access rights by introducing primary users and dependent users with distinct roles and permissions. Primary users can delegate access to dependent users while maintaining overall card control. This segmentation allows flexible card management without requiring the card issuer to manage individual access relationships, resolving the contradiction between flexibility and system complexity.
2Ease of operation
If cardholders delegate full access to dependent users, then ease of card management is improved, but control over card usage is reduced
Solution Approach 1:
The patent implements dynamic access control where primary users can revoke or modify dependent user access at any time. The system allows access levels to change from full access to restricted access or complete revocation, providing both ease of management through delegation and maintained control flexibility through the ability to dynamically adjust permissions.
Solution Approach 2:
The patent changes the parameter of access control by introducing revocable delegation mechanisms. Dependent users can be granted full access, restricted access, or have access completely revoked based on the primary user's needs. This parameter change enables easy card management through delegation while preserving control flexibility through adjustable access levels.
3Adaptability or versatility
If card issuers maintain all cardholder relationships and access records, then centralized control is maintained, but system adaptability and user independence are reduced
Solution Approach 1:
The patent extracts the cardholder relationship management function from the card issuer system. Primary/dependent relationships, access delegation, and revocation capabilities are handled independently by cardholders through a card management system, not requiring issuer knowledge or involvement. This extraction improves user independence while the issuer maintains centralized control through existing validation mechanisms.

AI summary
A method for managing a payment card is disclosed. The method comprises allowing a first party with access rights to a payment card managed by a card management system to designate at least one second party to whom access rights to said payment card is to be granted; and allowing said at least on second party to have access rights to said payment card by said card management system; wherein a card issuer associated with the payment card is not aware of the existence of the at least one second party and hence cannot exert any control over the access rights of said at least one second party.
