NFC and MST Payment Modules Automatic Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electronic devices face inconvenience when making off-line payments as they need to select the appropriate communication method (NFC or MST) for transmitting payment information, which can be time-consuming and inefficient.
Innovation Solution
An electronic device equipped with both NFC and MST modules, along with a processor that selectively chooses the appropriate module for payment transmission based on a predefined schedule, allowing for seamless payment processing without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device supports both NFC and MST communication modules, then the adaptability to different payment receiving devices is improved, but the device complexity increases
Solution Approach 1:
The payment communication system is segmented into two independent modules: NFC module for near-field communication and MST module for magnetic stripe data transmission. Each module operates independently with its own communication protocol, allowing the device to support multiple payment receiving devices without requiring a single complex unified communication system.
Solution Approach 2:
The electronic device is designed with multi-functionality by incorporating both NFC and MST communication capabilities within a single device. This allows the device to universally support both NFC-based and MST-based payment receiving devices, enabling one device to perform multiple payment communication functions.
2Loss of time
If the user manually selects the communication method for payment, then the ease of operation is reduced, but the loss of time is minimized
Solution Approach 1:
The system implements self-service by automatically detecting the payment receiving device type and selecting the appropriate communication module (NFC or MST) without requiring user intervention. The processor autonomously determines which module to use based on the detected device, eliminating the manual selection step from the payment process.
Solution Approach 2:
The system performs preliminary detection of the payment receiving device before the actual payment transaction. By detecting the device type in advance and pre-selecting the appropriate communication module, the system prepares the communication path beforehand, ensuring seamless payment execution without time-consuming user selection during the transaction.
3Ease of operation
If the processor automatically selects the communication module, then the ease of operation is improved, but the use of energy increases
Solution Approach 1:
The processor implements periodic detection and selection of the appropriate communication module based on the payment receiving device type. Instead of continuously operating both modules, the system periodically activates only the required module (NFC or MST) based on real-time detection, reducing unnecessary power consumption while maintaining automatic selection functionality.
Solution Approach 2:
The system dynamically changes the operational state of communication modules based on detected parameters of the payment receiving device. When a payment device is detected, the processor adjusts the activation state of NFC and MST modules accordingly, enabling only the relevant module to consume power, thus optimizing energy usage while maintaining ease of operation.
