Payment App Deactivation via Dummy Program Substitution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When an electronic device providing a payment function is lost, users face the risk of monetary loss due to the inability to control or deactivate the payment function remotely, allowing potential misuse.
Innovation Solution
An electronic device and method that include a communication module, memory, and processor to receive payment information, store it, and upon request, deactivate the payment application by replacing it with a dummy program, thereby preventing unauthorized use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If payment information is stored in the electronic device for convenient payment function, then payment convenience is improved, but security risk increases when the device is lost
Solution Approach 1:
The patent extracts the payment information storage function from the main payment application by introducing a separate dummy program. When a loss prevention request is received, the real payment application is replaced with this dummy program that cannot process payments, effectively separating the payment functionality from the device while maintaining the application structure.
Solution Approach 2:
The patent creates a dummy program that copies the external appearance and structure of the real payment application but lacks the actual payment processing capability. This copy serves as a protective measure that maintains user interface consistency while preventing unauthorized payment operations.
2Object-affected harmful factors
If the payment application is deactivated to prevent misuse, then security is improved, but the legitimate payment function becomes unavailable
Solution Approach 1:
The patent implements a dynamic state change mechanism where the payment application can transition between active and dummy states based on received requests. The system dynamically replaces the payment application with a dummy program when loss prevention is requested, and can restore the original application when restoration is requested, allowing flexible control over payment availability.
Solution Approach 2:
The patent applies preliminary anti-action by proactively replacing the payment application with a dummy program before any unauthorized payment attempts can occur. This preventive measure blocks malicious use in advance while maintaining the capability to restore legitimate functionality through restoration requests.
3Object-affected harmful factors
If remote control capability is added to deactivate payment function, then security control is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary mechanism in the form of a server that receives loss prevention and restoration requests from remote devices. The server communicates with the lost electronic device to trigger application replacement or restoration, enabling remote control without requiring complex direct device-to-device communication protocols.
Solution Approach 2:
The dummy program serves multiple functions: it maintains the external appearance of a working payment application for user interface consistency, prevents unauthorized payment processing, and can be replaced to restore functionality. This multi-functional element reduces the need for separate security mechanisms.

AI summary
An electronic device and a method for supporting a payment function are disclosed. The electronic device includes a communication module, at least one memory configured to store a payment application and payment information relating to the payment application, and a processor, wherein the memory stores instructions that, when executed, cause the processor to receive the payment information from an external device via the communication module and store the received payment information in the memory, receive a stop or deactivation request of the payment application and/or the payment information from the external device via the communication module, and in response to the request, stop or deactivate the payment application and/or the payment information.
