Mobile Device Optical Payment Transaction System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile payment systems lack convenience and practicality for individuals and organizations, as they require carrying physical credit/debit cards and cash, and existing technologies are not well-suited for point-of-sale transactions using wireless devices.
Innovation Solution
A method and apparatus that utilize optical representations, such as barcodes or QR codes, displayed on a mobile device to communicate transaction data between devices, enabling secure and efficient payment processing through encryption and decryption, allowing mobile devices to act as both buyer and seller devices for completing transactions over a communications network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile devices are used for point-of-sale transactions, then convenience is improved by eliminating the need to carry physical cards and cash, but device complexity increases due to the need for encryption, decryption, and network communication protocols
Solution Approach 1:
The patent uses optical representations (visual codes) to copy and transmit payment information between devices. Instead of physically carrying cards, the payment data is copied into visual formats that can be displayed and scanned, eliminating the need for physical card handling while maintaining security through encrypted representations
Solution Approach 2:
The patent introduces a third device as an intermediary that facilitates communication between buyer and seller devices. This intermediary handles the complex encryption and decryption operations, allowing the mobile devices to perform simple display and scanning functions while the intermediary manages the security protocols and network communication
2Adaptability or versatility
If existing mobile devices are used for transactions, then adaptability is improved by leveraging available technology, but reliability decreases due to security concerns with wireless communications
Solution Approach 1:
The patent replaces traditional mechanical card-swiping or contactless NFC systems with optical representation technology. Visual codes are displayed on device screens and scanned by cameras, substituting the mechanical/card-based payment system with an optical field-based system that maintains security while using existing mobile device capabilities
Solution Approach 2:
The patent creates encrypted copies of payment information in optical representations. Instead of transmitting raw card data wirelessly which is vulnerable to interception, the system creates encrypted visual copies that can only be read and processed by authorized devices, maintaining security while enabling wireless transaction capability
3Reliability
If encryption is used for payment information, then security is improved, but processing time increases due to encryption and decryption operations
Solution Approach 1:
The patent performs encryption operations in advance before the actual transaction occurs. Payment information is encrypted and stored in advance, so that during the transaction process, the system only needs to retrieve and verify pre-encrypted data rather than performing encryption in real-time, significantly reducing transaction processing time while maintaining security
Solution Approach 2:
The patent uses visual optical representations to copy encrypted payment data in a format that can be quickly scanned and processed. The encrypted information is converted into visual codes that can be read by cameras and processed rapidly, avoiding the time-consuming process of decrypting and re-encrypting data during transactions
Data Source
AI summary
A first device may be used to complete a transaction by receiving information for completing a transaction between a first entity associated with the first device and a second entity associated with a second device, causing a payment to be made to the second entity by communicating with a third device via a communications network, receiving an encrypted payment confirmation from the third device, and providing the encrypted payment confirmation to the second device, thereby completing the transaction.
