POS Terminal Barcode Wireless Tag Data Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article sales data processing systems cannot distinguish between barcode and wireless tag formats for article identification, leading to uncertainty and potential double processing of sales data, especially when wireless tags are broken.
Innovation Solution
An article sales data processing apparatus with separate reading units for barcode and wireless tag formats, a determination unit to identify the format, and a control unit to display sales data separately for each format, allowing operators to recognize the processing method and prevent double registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system processes articles using both barcode and wireless tag formats without distinction, then the system maintains versatility in handling different article types, but the operator cannot recognize the processing method leading to potential double registration and data integrity issues
Solution Approach 1:
The display area is segmented into multiple regions, with each region dedicated to displaying sales data from a specific input format (barcode or wireless tag). This segmentation allows operators to visually distinguish which articles were processed through which format, preventing double registration while maintaining support for both formats.
Solution Approach 2:
Different regions of the display are assigned different qualities or characteristics corresponding to different input formats. Each region is specifically optimized to show data from its associated format, providing localized information quality that helps operators identify the processing method for each article.
2Ease of operation
If the system uses a single unified display for all sales data regardless of input format, then the display simplicity is maintained, but the operator cannot distinguish between barcode and wireless tag processed articles
Solution Approach 1:
The display is divided into multiple segments or regions, each corresponding to a specific input format. This segmentation maintains ease of operation by providing a clear, organized layout while simultaneously improving reliability by enabling operators to distinguish and verify the input format for each displayed article.
Solution Approach 2:
The display organization transitions from a single-dimensional unified list to a multi-dimensional structured layout where articles are arranged by input format. This dimensional change preserves operational simplicity through systematic organization while adding the dimension of format identification that ensures data accuracy.
3Productivity
If the system processes articles collectively using wireless tag format, then processing speed is dramatically improved, but the system cannot handle articles with broken wireless tags or those requiring barcode processing
Solution Approach 1:
The POS terminal is designed with multi-functionality to handle both barcode and wireless tag input formats. This universality enables the system to process articles at high speed using wireless tags when available, while simultaneously maintaining the capability to process articles with broken wireless tags or those designated for barcode processing, thus resolving the contradiction between productivity and adaptability.

AI summary
An article sales data processing apparatus comprises a first reading unit configured to read an article identification code from a first medium attached to an article, a second reading unit configured to read the article identification code from a second medium attached to the article, a determination unit configured to determine whether the article identification code is the code read by the first reading unit or the code read by the second reading unit, and a control unit configured to separately display, on a display unit, article sales data obtained from the article identification code determined to have been read by the first reading unit and article sales data obtained from the article identification code determined to have been read by the second reading unit.
