Air Sign Transaction Input for Secure Merchant Payments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transaction methods using NFC and BLUETOOTH® are insecure and susceptible to data interception, posing risks in transactions with merchants.
Innovation Solution
A motion-enabled transaction system that utilizes air sign symbols, captured through user devices or merchant devices, to initiate and confirm transactions, integrating with a back-end server for data matching and authorization, reducing the need for traditional point of sale systems and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If NFC or BLUETOOTH® is used for transactions, then transaction convenience is improved, but security deteriorates due to susceptibility to data interception
Solution Approach 1:
The patent replaces wireless communication systems (NFC, BLUETOOTH®) that are susceptible to interception with a motion-based input system. Users create unique motion patterns (air signs) that are captured by accelerometer data, transforming the transaction initiation from wireless data transmission to physical gesture recognition, thereby eliminating the security vulnerability to data interception while maintaining convenience
Solution Approach 2:
The system changes the fundamental parameter of transaction initiation from electronic signal transmission to physical motion capture. By using accelerometer data to capture motion patterns in three-dimensional space and converting them into unique identifiers, the system fundamentally alters how transactions are initiated, making the process both convenient and secure against traditional interception methods
2Reliability
If traditional point of sale systems are used, then transaction reliability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the core authentication function from complex point of sale systems and merchant infrastructure. By enabling users to initiate transactions through simple motion gestures captured by their own devices without requiring merchant-side POS systems, the invention removes the need for complex transaction initiation hardware at merchant locations while maintaining secure transaction processing
Solution Approach 2:
The system enables users to perform transaction initiation themselves through motion gestures captured by their personal devices. The user's device autonomously captures accelerometer data, creates the air sign identifier, and transmits the transaction request, eliminating the need for traditional merchant point of sale systems and reducing overall system complexity
Data Source
AI summary
Systems and methods for motion-enabled transactions are disclosed. The system may allow users to complete transactions with merchants via an air sign input. The system may receive a motion-enabled transaction request comprising an air sign input. The system may determine a stored air sign symbol based on the air sign input. The system may retrieve a merchant identifier, a transaction type, and a transaction cost based on the determined stored air sign symbol. The system may transmit a transaction confirmation comprising the merchant identifier, the transaction type, and the transaction cost. In response to the user confirming the transaction confirmation, the system may authorize and process the transaction.
