Checkout Device Screen Segmentation for Settlement Operability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing checkout devices, such as POS terminals, face challenges in improving operability, particularly in displaying information related to settlement method selections and changes during the transaction process.
Innovation Solution
A checkout device and method that display a transaction amount, settlement methods, and information about the selected settlement method on the same screen, allowing for improved operability by integrating a processor to manage and display these elements effectively, including a first display area for the transaction amount, a second area for selectable settlement methods, and a third area for information about the selected method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a software keyboard is displayed in one of two display areas on a single display screen, then operability is improved, but display of information related to settlement method selections and changes remains insufficient
Solution Approach 1:
The display screen is divided into three distinct display areas: a first display area showing transaction amount, a second display area showing selectable settlement methods, and a third display area showing information about the selected settlement method. This segmentation allows each area to specialize in displaying specific information, improving both operability and information completeness without compromising either aspect.
2Loss of information
If multiple display areas are formed on a single display screen, then information display is improved, but device complexity increases
Solution Approach 1:
A single display screen is designed to perform multiple functions by accommodating three different display areas that serve different purposes: transaction amount display, settlement method selection display, and selected method information display. This multi-functional design eliminates the need for separate display devices while maintaining comprehensive information display capabilities, thus improving information completeness without proportionally increasing device complexity.

AI summary
According to an embodiment, a checkout device has a processor configured to acquire merchandise information for an item being registered for purchase in a transaction, and then execute a settlement process for the transaction based on the acquired merchandise information. The processor is configured to cause a display screen to display, on the same screen at the same time, a first display area in which a transaction amount for the transaction is displayed, a second display area in which at least one settlement method to be used for the settlement process is displayed in a selectable manner, and a third display area in which information about a selected settlement method is displayed.
