Lock Screen Scanning Code for Mobile Payment Power Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile device payment processes are time-consuming and error-prone, requiring users to unlock their devices, navigate through multiple steps, and search for specific software applications to conduct transactions, especially when numerous apps are installed.
Innovation Solution
A method that temporarily replaces the lock screen wallpaper of a mobile device with a scanning code (e.g., QR code or barcode) encoding payment information, allowing for cloud-based transactions without unlocking the device, using GPS, NFC, RFID, or Bluetooth to identify the business location and activate the display with the scanning code as the lock screen wallpaper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the user follows the conventional process to conduct a transaction (unlock phone, find software, navigate to payment section), then the transaction can be completed, but the process is time-consuming and error-prone
Solution Approach 1:
The system performs preliminary actions by automatically detecting when the mobile device is at a business location and proactively displaying the scanning code on the lock screen before the user needs to initiate a transaction. This eliminates the need for users to manually locate and launch payment software, as the payment interface is already prepared and visible on the lock screen.
Solution Approach 2:
The system enables self-service by automatically managing the payment interface display based on location detection. The mobile device autonomously determines when to show the scanning code on the lock screen by detecting proximity to business locations via GPS, NFC, RFID, or Bluetooth, without requiring user intervention to navigate through applications.
2Adaptability or versatility
If the user has numerous software applications installed, then the device functionality is enhanced, but locating the payment software becomes more difficult and time-consuming
Solution Approach 1:
The system extracts the payment scanning code from within the payment application and displays it directly on the lock screen. This separation allows the payment functionality to be accessed independently of the application structure, eliminating the need for users to search through numerous installed applications to find the payment software.
3Ease of operation
If the mobile device display is kept active to show the scanning code, then transactions can be conducted without unlocking, but power consumption increases
Solution Approach 1:
The system uses periodic location detection (via GPS, NFC, RFID, or Bluetooth) to determine when the device is at a business location, and only activates the display with the scanning code when needed. This periodic checking approach allows the device to maintain low power consumption during normal use while enabling quick activation of the payment interface when required.

AI summary
Power is conserved in a mobile device having a lock screen wallpaper by: (1) identifying the mobile device is at a business location, (2) temporarily replacing lock screen wallpaper in the mobile device to an image having a scanning code, the scanning code encoding payment information for a cloud-based transaction at the business location, (3) activating a display of the mobile device and rendering the image having the scanning code as the lock screen wallpaper on the activated display of the mobile device which remains in the screen locked state; and (4) conserving power in the mobile device by providing the image having the scanning code as the lock screen wallpaper of the mobile device, without having to unlock the mobile device.
