Smart Card Autonomous Payment Routing and Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing payment systems, including web browsers and digital wallets, expose sensitive transaction information to security risks due to substandard security measures and the involvement of third-party systems, increasing the likelihood of data breaches and unauthorized access.
Innovation Solution
A smart card platform with autonomous payment routing capabilities, featuring a microprocessor, display screen, wireless communication, and non-transitory memory, which allows users to reroute payments through alternate channels without exposing sensitive information to third-party systems, using a digital contact directory and AI-based recommendation engines for secure authorization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users enter credit card information into web browsers or mobile applications, then online transactions can be executed, but sensitive transaction information is exposed to security risks
Solution Approach 1:
The patent extracts sensitive transaction information handling from third-party systems (web browsers, mobile applications) and places it directly on the smart card. The smart card contains a microprocessor and memory that can process payment transactions locally, eliminating the need to transmit sensitive card data to external systems. This extraction of the critical function to a secure, isolated environment resolves the contradiction by maintaining ease of operation while dramatically improving security.
Solution Approach 2:
The smart card acts as an intermediary device between the user and the payment network. Instead of directly exposing card information to merchants or payment processors, the smart card mediates the transaction by generating secure payment tokens locally and communicating only with authorized payment networks. This intermediary role protects sensitive information while enabling seamless transactions.
2Reliability
If digital wallets are used to improve security, then transaction security is enhanced, but sensitive information is still captured by third-party applications
Solution Approach 1:
The patent extracts the payment processing function from third-party digital wallet applications and implements it directly on the smart card. The microprocessor on the card can execute payment transactions independently without requiring third-party application intermediaries. This eliminates the security vulnerability where third-party apps could capture or misuse sensitive information, while maintaining the convenience of contactless payments.
Solution Approach 2:
The smart card provides self-service payment processing capabilities through its integrated microprocessor and secure element. The card can autonomously generate payment tokens, manage transaction state, and communicate securely with payment networks without requiring external application control. This self-sufficiency removes the attack surface created by third-party applications while maintaining user convenience.
3Productivity
If more parties handle sensitive transaction information, then transaction processing capability increases, but risk of inadvertent disclosure increases
Solution Approach 1:
The patent extracts sensitive information handling from the distributed network of third-party systems and consolidates it within the smart card's secure element. The card's microprocessor processes transactions locally using stored payment data, eliminating the need for multiple external parties to access sensitive information. This extraction maintains transaction processing capability while reducing the number of potential security vulnerabilities.
Solution Approach 2:
The patent segments the payment system into distinct functional components: the smart card handles sensitive data storage and processing, the payment network handles authorization and clearing, and the merchant system handles goods delivery. Each segment operates with only the information necessary for its function, minimizing exposure of sensitive data while maintaining overall system productivity.
Data Source
AI summary
Systems and methods for autonomous payment routing are provided. A method may include storing in a smart card a database of contacts accessed from a digital contact directory. The method may include receiving a request to reroute a payment via an alternate payment channel, the payment including a recipient and an amount, and the alternate payment channel originating from an account associated with one of the contacts in the database. The method may also include resolving, via a wireless communication element that is embedded in the smart card, routing information for the account. The method may also include transmitting, to an administrator of the account, a request for authorization to reroute the payment, and, when authorization is received, executing the payment via the alternate payment channel.
