Automated NFC Pressure Testing via Computer Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional NFC pressure test methods are inconvenient and wasteful of manpower, as they require manual movement of NFC tag cards near and away from a mobile terminal for repeated readings, which is inefficient and time-consuming.
Innovation Solution
A method and system utilizing a mobile terminal and storage device that automates NFC pressure tests by connecting a computer terminal to control the NFC process, presetting the number and frequency of cyclic card readings, and modifying a service flag bit to simulate the action of moving NFC tag cards, allowing the mobile terminal to perform tests automatically without manual intervention.

Engineering Contradiction Analysis
1Ease of operation
If manual movement of NFC tag cards is used for pressure testing, then the test can be completed, but the process is inconvenient and wastes manpower
Solution Approach 1:
A computer terminal serves as an intermediary between the operator and the mobile terminal. The computer terminal automatically controls the mobile terminal to perform NFC reading operations cyclically, eliminating the need for manual movement of NFC tag cards. The computer terminal sends control instructions to the mobile terminal and retrieves test results automatically.
Solution Approach 2:
The system enables self-service automation where the computer terminal autonomously manages the entire testing process. After initial setup, the system automatically initiates NFC services, controls reading operations, manages service flag bits, and collects results without requiring continuous human intervention throughout the testing cycle.
2Productivity
If manual movement of NFC tag cards is used for pressure testing, then the test can be completed, but it is time-consuming and inefficient
Solution Approach 1:
The system implements periodic automated actions where the computer terminal controls the mobile terminal to cyclically perform NFC reading operations. The testing process automatically repeats reading operations for multiple NFC tag cards in sequence, with preset numbers and frequencies, significantly reducing the time required compared to manual operations.
Solution Approach 2:
The automated system maintains continuous useful action by eliminating idle time between operations. The computer terminal continuously manages the testing process, automatically transitioning between different NFC tag cards and maintaining the NFC service in an enabled state throughout the testing cycle, maximizing productivity.
3Extent of automation
If the NFC service is continuously enabled for automated testing, then automation is achieved, but the service flag bit management becomes complex
Solution Approach 1:
The system implements feedback mechanisms where the computer terminal monitors the state of service flag bits and automatically adjusts control instructions accordingly. The mobile terminal reports back on service status, and the computer terminal responds by enabling or disabling services as needed, creating a closed-loop control system that manages complexity through automated state tracking.

AI summary
Provided are a mobile terminal-based NFC stress testing method and system, and a storage device. The method comprises: connecting to a computer to acquire a preset count and a preset frequency; activating an NFC service; determining whether a flag bit is enabled, and if so, detecting an NDEF message, or if not, waiting for the computer terminal to modify the flag bit to be enabled before detecting an NDEF message; and uploading, by a hardware abstraction layer, the NDEF message to an NFC application, disabling a service flag bit, and returning to wait for the computer terminal to modify the flag bit, until detection is complete.
