Solution Overview

Problem

When multiple types of radio frequency cards are integrated into a mobile terminal, users often experience card swiping failures due to incorrect card selection, leading to a suboptimal user experience, as different cards correspond to specific radio frequency transmit devices and selecting the wrong default card results in unsuccessful transactions.

Innovation Solution

The mobile terminal allows users to preset a mapping relationship between feature information, such as fingerprint or voiceprint data, and radio frequency card types, enabling the system to determine and invoke the correct card function based on user-specific feature input, thereby improving card swiping success rates and user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a default radio frequency card is selected for frequent use, then there is a relatively high probability of successful card swiping, but when the radio frequency transmit device does not correspond to the default card type, card swiping fails

Engineering Contradiction:
Improvecard swiping success rateVSAvoidcompatibility with different radio frequency transmit devices
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary identification of the radio frequency transmit device type before card swiping, and pre-selects the corresponding radio frequency card function. This is achieved by detecting the transmit device type first, then automatically invoking the matching card function, thereby avoiding the need for users to manually select cards and ensuring high success rate while maintaining versatility.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides feedback to users when the default card is incompatible with the transmit device, prompting users to select from alternative card options. This feedback mechanism ensures that users can successfully complete transactions even when the default card is not appropriate, thus maintaining both high success rates and adaptability.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If multiple types of radio frequency cards are integrated into one mobile terminal, then user convenience is improved, but determining which card function to invoke becomes more complex

Engineering Contradiction:
Improveuser convenienceVSAvoidcard function selection complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system automatically identifies the radio frequency transmit device type and self-selects the corresponding card function without requiring user intervention. This self-service mechanism simplifies the user experience while managing the complexity of multiple card types internally, as the system handles the selection logic autonomously.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mobile terminal is designed with multi-functionality to support multiple radio frequency card types within a single device. The system provides a unified interface for card management while internally handling the complexity of different card types, making the device versatile and convenient for users.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If users manually select a default radio frequency card, then card swiping can be performed, but user experience deteriorates when the wrong default card is selected

Engineering Contradiction:
Improvetransaction efficiencyVSAvoiduser experience
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system performs preliminary identification of the radio frequency transmit device type before card swiping, and pre-selects the corresponding radio frequency card function. This eliminates the need for users to manually select cards and prevents wrong card selection, thereby maintaining high transaction efficiency while improving user experience.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The manual card selection process is replaced with an automated identification and selection system. The system automatically detects the transmit device type and invokes the appropriate card function, replacing the mechanical user action of card selection with an automated electronic process, thereby improving both efficiency and user experience.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Embodiments of this application disclose a method and an apparatus for invoking a radio frequency card function. The method includes: monitoring a feature input event, and obtaining feature information of a user from the feature input event obtained through monitoring; determining, based on a mapping relationship between the feature information and a radio frequency card type, a target radio frequency card type corresponding to the feature information of the user; and invoking a radio frequency card function corresponding to the target radio frequency card type. It can be learned that in the embodiments of this application, different radio frequency card types may be distinguished based on the feature information of the user, so that the radio frequency card function corresponding to the target radio frequency card type corresponding to the feature information of the user can be invoked based on the feature information of the user. This further improves a card swiping success rate and improves user experience.
