Card Device Reward Comparison and Credit Number Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information systems do not assist users in selecting cards that offer rewards such as points or discounts, and they cannot automatically change credit card numbers, making it difficult for users to maximize rewards and secure transactions.
Innovation Solution
An information system that includes a store information storage unit, a store specifying information accepting unit, a reward-related information acquisition unit, and a credit card number changing unit, which helps users select the most rewarding card by comparing reward information across multiple cards and automatically updates credit card numbers based on predetermined conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users carry multiple cards to receive different rewards at different stores, then the user can access more card services and rewards, but the user burden increases due to carrying and managing multiple cards
Solution Approach 1:
The patent combines multiple card functions and reward programs into a single integrated card system. The card device stores and manages multiple card information sets, allowing users to access different card services and rewards through one card rather than carrying multiple separate cards.
Solution Approach 2:
The integrated card system provides multi-functionality by supporting multiple card types and reward programs simultaneously. The card can be used at different stores for different reward programs, making a single card universal for various purposes.
2Loss of information
If the system provides detailed reward information for multiple cards, then the user can make informed decisions about which card to use, but the information processing complexity increases
Solution Approach 1:
The system automatically compares reward information across multiple cards and presents the most beneficial option to the user. The card device or terminal device performs the information processing and comparison tasks autonomously, reducing the complexity burden on the user while maintaining complete reward information availability.
Solution Approach 2:
The system provides feedback to the user about which card will yield the highest reward based on the current store and purchase context. This feedback mechanism simplifies the decision-making process by highlighting the optimal choice rather than requiring the user to manually compare all options.
3Reliability
If the system automatically changes credit card numbers, then transaction security is improved, but the automation complexity and potential for errors increases
Solution Approach 1:
The system automatically selects and switches between different credit card numbers based on predetermined conditions such as reward optimization or security considerations. This self-service automation manages credit card number switching without user intervention, improving security while managing complexity through rule-based automation.

AI summary
[Problem] To assist a user to use a card with which the user can receive a beneficial reward. [Solution] An information system including: a store information storage unit in which one or more pieces of store information are stored, each piece of store information including a store identifier that identifies a store, and two or more pieces of card information each including a card identifier that identifies a card that is available at the store and reward information regarding a reward that is to be gained when the card is used; a store specifying information accepting unit that accepts store specifying information that specifies a store at which a card is used; an owned-card specifying information acquisition unit that acquires owned-card specifying information that specifies two or more cards owned by a user; a reward-related information acquisition unit that uses two or more pieces of reward information included in card information regarding two or more cards corresponding to two or more pieces of card information included in store information regarding a store specified by the store specifying information, out of two or more cards specified by the owned-card specifying information, to acquire reward-related information related to reward information regarding two or more cards that the user can use at the store; and a reward-related information output unit that outputs the reward-related information.
