Solution Overview

Problem

Existing payment cards lack the ability to integrate additional functions such as tracking customer behavior and offering dynamic rewards without compromising security, and existing customer reward programs fail to dynamically respond to customer needs and demands.

Innovation Solution

A smart card that functions as both a payment card and a customer behavior tracker, storing data on customer visits and rewards, with integrated cryptographic security features and a blockchain for authenticity verification, allowing it to operate independently of network integration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If additional functions are added to payment cards to track customer behavior and provide dynamic rewards, then customer engagement and versatility are improved, but security and safety are compromised

Engineering Contradiction:

ImprovefunctionalityVSAvoidsecurity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system divides the card functionality into separate components: a contactless RFID card for customer behavior tracking and a traditional payment card for transactions. This segmentation allows each component to be optimized for its specific function with appropriate security measures, enabling versatile functionality without compromising overall system security.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary system consisting of a processor and database that acts as a mediator between the contactless card and the reward distribution mechanism. This intermediary securely manages the tracking data and reward calculations, preventing direct access to sensitive information while enabling dynamic reward provision based on customer behavior.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If coupon values are made dynamic to respond to product demand fluctuations, then customer engagement and sales optimization are improved, but system complexity increases

Engineering Contradiction:

Improvedynamic response capabilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements dynamic coupon values that automatically adjust based on real-time product demand data. The processor continuously receives demand information, calculates appropriate reward values, and updates the database, enabling the coupon system to adapt dynamically to changing conditions without requiring manual intervention.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system establishes a feedback loop where product demand data is continuously collected, analyzed by the processor, and used to adjust coupon values accordingly. This feedback mechanism enables automatic optimization of rewards based on actual sales performance and customer behavior patterns, reducing the need for complex manual management.

Inventive Principle:

Principle #23Feedback

3Loss of information

If contactless RFID technology is integrated into payment cards for behavior tracking, then data collection capability is improved, but vulnerability to theft and fraud increases

Engineering Contradiction:

Improvedata collection capabilityVSAvoidtheft and fraud vulnerability

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the data collection function from the traditional payment card by implementing a separate contactless RFID card. This extracted component is dedicated solely to tracking customer behavior and collecting data, while the original payment card retains its secure transaction functionality. This separation reduces the attack surface for fraud while maintaining comprehensive data collection capabilities.

Inventive Principle:

Principle #2Taking out (Extraction)
