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

VSEngineering 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

Engineering Contradiction:
Improveconvenience of paymentVSAvoiddata processing delay
Core Design Contradiction:
Ease of operationVSLoss of time

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

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If physical RF cards are used for payment, then transaction capability is improved, but real-time monitoring capability deteriorates

Engineering Contradiction:
Improvetransaction capabilityVSAvoidreal-time monitoring capability
Core Design Contradiction:
Ease of operationVSLoss of information

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

Inventive Principle:
Principle #23Feedback

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

Inventive Principle:
Principle #24Intermediary (Mediator)

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).
