Solution Overview

Problem

Current contactless card systems face challenges in providing robust data security, authentication, and verification, especially in multi-issuer environments, where each issuer must maintain separate systems for contactless card features, leading to high costs and complexity.

Innovation Solution

A centralized switchboard system is introduced to manage and secure contactless card functions across multiple issuers, using a single platform for tap-to functionalities, with features like session management, issuer identification, and secure communication protocols to maintain data integrity and security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If each issuer maintains separate systems for contactless card features, then data security and authentication can be maintained, but system complexity and costs increase significantly

Engineering Contradiction:

Improvedata securityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple issuer-specific contactless card systems into a single centralized switchboard platform that handles functions for multiple issuers. The switchboard consolidates session management, validation, and communication protocols into one unified system, reducing overall complexity while maintaining security through centralized control and standardized processes.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The switchboard acts as an intermediary between client devices and multiple issuers, mediating all contactless card functions. Instead of direct issuer-device connections that create complexity, the switchboard intermediates by receiving requests, routing them appropriately, and managing sessions, thereby simplifying the system architecture while preserving security through controlled access points.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If a centralized system is used for multiple issuers, then costs and complexity are reduced, but data security and authentication challenges increase

Engineering Contradiction:

Improvesystem complexityVSAvoiddata security

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The centralized switchboard system segments different issuer operations into isolated processing streams, with each issuer's data and validation logic handled separately within the unified platform. This segmentation allows the system to maintain security boundaries between issuers while benefiting from centralized management, preventing security risks from propagating across the entire system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system changes security parameters by implementing standardized authentication protocols and session management rules that apply uniformly across all issuers. By establishing consistent security parameters (encryption standards, session timeouts, validation rules) in the centralized system, the patent maintains strong security posture while reducing the complexity of managing diverse security implementations.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If separate issuer systems are maintained, then data integrity can be ensured, but transaction efficiency and cost-effectiveness decrease

Engineering Contradiction:

Improvedata integrityVSAvoidtransaction efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The switchboard is designed as a universal platform that handles multiple issuer functions through a single system. It performs validation, session management, and communication for different issuers using standardized processes, enabling the system to maintain data integrity through consistent validation rules while improving transaction efficiency by eliminating redundant operations across separate systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Reliability

If contactless card functions are processed through multiple separate systems, then authentication can be performed, but processing time and operational costs increase

Engineering Contradiction:

ImproveauthenticationVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The switchboard performs preliminary actions by pre-establishing session parameters, validation rules, and communication protocols before actual contactless card transactions occur. Session information including nonces and validation criteria are prepared in advance, allowing rapid authentication processing when transactions occur, thereby reducing processing time while maintaining rigorous authentication standards.
