Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
NFC-enabled terminal devices face limitations in emulating physical RF cards, leading to delayed data processing and real-time monitoring issues, particularly affecting elderly or child users.
Innovation Solution
Equipping NFC-enabled terminal devices with an RF card and implementing a method to detect entry and exit from an RF field within a preset time, allowing real-time reading and sending of payment records to a secondary device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If NFC-enabled terminal devices emulate physical RF cards, then convenience of payment is improved, but real-time data processing capability deteriorates
Solution Approach 1:
The patent introduces a server as an intermediary component that receives payment records from the terminal device and sends notifications to designated second terminal devices. This mediator enables real-time data processing and notification without requiring the emulated RF card itself to have processing capabilities, thus resolving the contradiction between emulation convenience and real-time processing capability
Solution Approach 2:
The system performs preliminary actions by pre-configuring notification rules, designating second terminal devices, and establishing communication channels before payment transactions occur. This allows the system to immediately process and notify payment records in real-time without delay, maintaining both emulation convenience and real-time processing capability
2Ease of operation
If physical RF cards are used for payment, then transaction capability is improved, but real-time monitoring capability deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the server receives payment records from the terminal device and automatically sends notifications to second terminal devices. This closed-loop feedback system ensures that payment information is immediately transmitted and monitored in real-time, preventing information loss while maintaining transaction capability
Solution Approach 2:
The server acts as an intermediary that bridges the physical RF card transaction system and the digital notification system. It receives transaction data from the terminal device and relays this information to second terminal devices, enabling real-time monitoring capability while preserving the simplicity of physical card transactions

AI summary
A data processing method and system, and a terminal and a computer-readable storage medium. The data processing method comprises: detecting whether a first terminal enters a radio-frequency field (101), wherein the first terminal has enabled a near field communication (NFC) function, the first terminal is provided with a radio-frequency card, and the radio-frequency card performs consumption by means of the radio-frequency field; when the first terminal enters the radio-frequency field, and leaves the radio-frequency field within a preset time, reading a consumption record of the radio-frequency card (102); and sending the consumption record to a second terminal (103).
