NFC Ring Terminal-Less Payment Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing NFC payment systems require a terminal to process transactions, limiting convenience and increasing the risk of data theft, as users must interact with shared devices for payment transactions.
Innovation Solution
A terminal-less NFC payment system using a user-worn NFC-scannable payment ring that enables secure, personal transactions between the ring and a customer device, eliminating the need for shared terminals and enhancing security through a communication-lockable design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal is used to process NFC payment transactions, then transaction processing capability is improved, but security risk increases due to interaction with shared devices
Solution Approach 1:
The patent extracts the payment processing capability from the shared terminal and embeds it directly into the user's personal device (NFC ring). The ring contains an NFC controller and payment application that can independently process transactions without requiring interaction with external terminals, thus eliminating the security risk of sharing data with public devices while maintaining full transaction capability
Solution Approach 2:
The patent introduces a communication-lockable mechanism as an intermediary between the NFC ring and external devices. The ring controller can selectively enable or disable NFC communication based on predefined conditions, acting as a mediator that controls information flow and prevents unauthorized data access while allowing legitimate transactions
2Reliability
If a terminal is required for NFC payments, then transaction security is improved through controlled processing, but convenience deteriorates due to additional equipment requirements
Solution Approach 1:
The patent merges the NFC communication capability, payment application, and security control mechanisms into a single wearable ring device. This integration eliminates the need for separate terminals, smartphones, or other external equipment, allowing users to make payments simply by wearing the ring and approaching the payment point, thus maximizing convenience while maintaining security
Solution Approach 2:
The NFC ring is designed to autonomously handle all payment processing functions including authentication, transaction execution, and security verification. The ring controller independently manages communication with payment systems without requiring user intervention or external device assistance, enabling truly hands-free, self-service payments
3Productivity
If traditional NFC payment methods are used requiring terminals and websites, then transaction processing is improved, but time consumption increases due to multiple interaction steps
Solution Approach 1:
The payment application and authentication credentials are pre-loaded and configured within the NFC ring during manufacturing or initial setup. This preliminary configuration eliminates the need for real-time website interactions, account logins, or manual data entry during transactions, reducing payment time to a simple tap while maintaining full transaction processing capability
