NFC Terminal User Interaction Data Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing NFC technologies require users to manually select applications and data for each service, which is inconvenient and inefficient, as they need to execute an application and select corresponding data each time they use a service based on NFC, lacking the ability to transmit only necessary data reflecting user intention without repeated selection processes.
Innovation Solution
A method for terminals to map user interactions, such as motion, fingerprint, or voice inputs, to specific data transmissions through NFC, allowing secure and predetermined data transmission based on pre-defined user interactions, eliminating the need for repeated application selection by storing user interaction-data mappings and transmitting data through a contactless NFC link.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual application selection and data selection processes are implemented for NFC services, then data transmission accuracy and user control are improved, but operation convenience and service efficiency deteriorate
Solution Approach 1:
The terminal pre-stores multiple sets of data corresponding to different services (payment, electronic key, business card) in advance. When a service is needed, the terminal automatically selects and transmits the corresponding pre-stored data without requiring manual selection, thus improving operation convenience while maintaining data transmission accuracy through pre-configured data sets
2Reliability
If manual application execution and data selection are required for each NFC service, then data security and user intention reflection are improved, but service efficiency and user experience deteriorate
Solution Approach 1:
The terminal performs automatic service selection and data transmission based on the detected user interaction type (motion, fingerprint, voice). The system serves itself by automatically matching the interaction type with the corresponding service and transmitting the appropriate data without human intervention, thereby improving service efficiency while maintaining security through interaction-based automatic selection
3Measurement precision
If repeated application selection processes are implemented for each NFC service, then user control and data accuracy are improved, but time consumption and operational complexity increase
Solution Approach 1:
The terminal pre-configures and stores multiple sets of service-specific data (payment information, electronic keys, business cards) before actual service execution. When a service is triggered by user interaction, the terminal immediately retrieves and transmits the corresponding pre-stored data without requiring repeated selection processes, thus eliminating time consumption while maintaining data selection accuracy through pre-configured data sets
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables secure and efficient data transmission corresponding to user interactions, reducing user intervention and improving service convenience by automatically selecting and transmitting relevant data through NFC, enhancing user experience and service efficiency.
Implementation Method 1
In the reader mode, the NFC device may transmit data by modulating a magnetic field and receive data according to the transmitted data
Implementation Method 2
In the card emulation mode, the NFC device may be manually operated to receive data by demodulating data from a magnetic field emitted from another reader device
