Smart Card Direct Communication for Secure Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing online transaction systems expose sensitive transaction information to security risks due to vulnerabilities in third-party systems, even when using digital wallets, as users often need to enter information into unsecured web browsers or applications, increasing the risk of data exposure and unauthorized access.
Innovation Solution
A smart payment card with embedded wireless communication, a microprocessor, and a touch-sensitive screen that allows users to perform direct online transfers without entering sensitive information into third-party systems, establishing a secure communication channel with a payment gateway for processing, thereby reducing exposure risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users enter sensitive transaction information into third-party web browsers or mobile applications, then transactions can be conducted online, but the risk of sensitive information exposure increases due to security vulnerabilities in these third-party systems
Solution Approach 1:
The smart card acts as an intermediary device between the user and third-party systems. It performs transactions locally using embedded communication interfaces and processing capabilities, eliminating the need to enter sensitive information into external web browsers or applications. The card's secure element processes transactions independently, with only non-sensitive data exchanged with third-party systems.
Solution Approach 2:
The smart card performs self-contained transaction processing using its embedded microprocessor, memory, and communication interfaces. The card autonomously generates and processes transaction data, communicates with payment gateways, and manages security credentials without requiring user input into third-party systems. This self-service capability eliminates exposure risks while maintaining online transaction functionality.
2Reliability
If digital wallets are used to improve security, then reliable security is achieved, but sensitive transaction information is still captured by third-party applications that can track and potentially disclose the information
Solution Approach 1:
The patent extracts the transaction processing function from third-party applications and relocates it to the smart card itself. By embedding the payment processing logic, communication interfaces, and security credentials directly in the card, the system eliminates the need for third-party applications to capture or track sensitive transaction information. Only essential transaction data is transmitted to payment gateways, not to intermediate applications.
3Productivity
If more parties handle sensitive transaction information, then transaction processing capability is enhanced, but the risk of inadvertent disclosure of sensitive information increases
Solution Approach 1:
The patent removes the sensitive information handling function from multiple third-party parties and consolidates it within the smart card's secure processing environment. The card's embedded processor and memory contain all necessary transaction processing capabilities, eliminating the need for users to input data into external applications. This reduces the number of parties exposed to sensitive information while maintaining full transaction processing capability through direct card-to-payment gateway communication.
Data Source
AI summary
Apparatus and methods are provided for a smart card which enables users to securely complete online transfers without entering sensitive transaction information into a third-party system. The smart card may include a touch-sensitive screen configured to display selectable transfer options. The smart card may include a microprocessor and wireless interface. The wireless interface may provide wireless communication capabilities and the ability to initiate online transfers based on information captured by the touch-sensitive screen. A card issuer may mint an NFT with data from a past transaction using the smart card. The smart card may display the NFT and an associated score on the touch-sensitive screen. The smart card may communicate with another smart card using near-field communication to share NFT and score data. The smart card may accept or decline a transaction based on one or more NFTs associated with the other card.
