Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers face difficulties in efficiently completing payment transactions using mobile devices due to the need to manually locate and activate a payment application, which slows down the process.
Innovation Solution
A 'no-touch' mobile checkout system that allows consumers to complete transactions by bringing their mobile device near an interface console, which automatically launches the payment application and displays a payment token without user action, using NFC communication or optical scanning depending on device capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a consumer manually locates and activates a mobile payment application to display a token, then the payment transaction can be completed with a physical token-like security, but the transaction process becomes time-consuming and inefficient
Solution Approach 1:
The payment application and token are pre-loaded and stored in the mobile device's memory before the transaction occurs. When the consumer approaches the POS terminal, the system automatically retrieves and displays the pre-stored token without requiring the consumer to manually locate or activate the application, thus eliminating transaction time delays while maintaining security through pre-established cryptographic credentials.
Solution Approach 2:
The mobile payment system performs automatic token retrieval, application launch, and display activation without consumer intervention. The system self-manages the entire token presentation process by detecting the POS terminal's presence, automatically launching the payment application, and displaying the token on the screen or through NFC, freeing the consumer from manual operations while ensuring secure transaction completion.
2Productivity
If the mobile device automatically launches the payment application and displays the token without user action, then the transaction efficiency is improved, but the device complexity increases due to automatic detection and launch mechanisms
Solution Approach 1:
The mobile device leverages existing universal components and protocols already present in modern smartphones, including NFC hardware, camera-based optical scanning, proximity sensors, and operating system-level automatic application launch capabilities. By utilizing these multi-functional existing features rather than building dedicated hardware, the system achieves automatic token presentation without significantly increasing device complexity.
Solution Approach 2:
The system employs an intermediary software layer that acts as a bridge between the hardware sensors (NFC, camera, proximity detector) and the payment application. This intermediary service monitors for POS terminal presence, triggers appropriate communication protocols, and manages the token display process, thereby simplifying the overall system architecture while enabling automatic operation without requiring complex direct hardware-to-application integration.
3Adaptability or versatility
If the system supports both NFC-enabled devices and non-NFC devices with automatic mode selection, then the adaptability to different consumer devices is improved, but the system complexity increases due to multiple communication protocols
Solution Approach 1:
Instead of having the mobile device initiate and manage multiple communication protocols actively, the system inverts the approach by having the POS terminal advertise its supported protocols and allowing the mobile device to passively respond based on its capabilities. The POS terminal emits broadcast signals indicating NFC or optical scanning availability, and the mobile device automatically selects and implements the appropriate protocol based on its hardware configuration, thereby reducing the complexity burden on the consumer device while maintaining broad adaptability.
Solution Approach 2:
The system dynamically changes operational parameters such as communication protocol selection, token display method (NFC data transfer versus optical code display), and authentication flow based on the detected device capabilities and environmental conditions. This parameter adaptation allows the same payment system to seamlessly accommodate both NFC-enabled and non-NFC devices without requiring separate dedicated systems, managing complexity through flexible parameter adjustment rather than structural duplication.

AI summary
A “no-touch” mobile checkout experience frees consumers from the need to manually locate and activate a mobile payment application in order to complete a transaction. The consumer simply brings his mobile device within close range of an interface console, which in various embodiments prompts the device to launch an application that causes display of a payment token without user action. If the consumer's device is not NFC-capable, the interface console can read a displayed token optically in the usual fashion.
