Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transfer systems, such as those requiring physical contact or NFC, face issues with security and convenience, particularly for merchants who need to facilitate secure data transactions.
Innovation Solution
The implementation of a method and system that uses wireless technologies to securely authenticate a payer by receiving a unique identifier from an item associated with the payer, sending a confirmation request to the payer's electronic device, and processing the transaction through an authentication system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical contact methods (magnetic card swiping) are used for data transfer, then security can be maintained through direct control, but the system requires physical approach and contact which reduces convenience and increases waiting time
Solution Approach 1:
The patent replaces mechanical contact-based data transfer (magnetic card swiping) with wireless communication technology. The system uses wireless signals to transmit data between the portable device and terminal without requiring physical contact, thereby eliminating the need for users to approach and physically interact with the terminal, reducing waiting time and improving convenience.
2Ease of operation
If close contact methods (NFC) are used for data transfer, then wireless communication is achieved, but the system still requires close proximity which maintains some security risks and limits convenience
Solution Approach 1:
The patent extends the data transfer range beyond close proximity by utilizing wireless communication in three-dimensional space. The system allows data transfer over distances significantly greater than NFC range, enabling users to transmit data without being in close contact with the terminal, thereby reducing security risks associated with close proximity while maintaining wireless convenience.
3Productivity
If wireless communication is used for data transfer, then convenience is improved, but security vulnerabilities arise where eavesdroppers can intercept information
Solution Approach 1:
The patent introduces an authentication system as an intermediary between the portable device and terminal. This intermediary verifies the authenticity of data transmissions through authentication protocols, ensuring that only legitimate transactions are processed. The authentication system acts as a security layer that prevents eavesdropping and unauthorized interception while maintaining the convenience of wireless communication.
4Loss of time
If contactless wireless methods are used, then convenience and speed are improved, but new security challenges emerge regarding unauthorized interception of transmitted information
Solution Approach 1:
The patent implements feedback mechanisms through authentication protocols that verify the legitimacy of data transmissions in real-time. The authentication system provides feedback to both the portable device and terminal to confirm successful authentication, creating a closed-loop security system that prevents unauthorized interception while maintaining fast transaction speeds.

AI summary
In one embodiment, a method comprises receiving a unique identifier from an item and sending a communication to an electronic device requesting that a user confirm a pending transaction, receiving input from the electronic device associated, and sending the received input to an authentication system for completing a transaction. In another embodiment, a system comprises a sensor, an authentication system, and a transaction processing system. The sensor is configured to emit energy and receive at least one first identifier, send at least one communication to an electronic device requesting a second identifier, receive at least one second identifier, and send the at least one first identifier and the at least one second identifier to the authentication system.
