Code Reader SKU Extraction for POS Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional readers are unable to delete the serial number from code data and transmit only the SKU code to external devices, such as POS terminals, when reading codes that include both SKU and serial number information.
Innovation Solution
A reader with a processor and scanner that can determine the type of code read, extract the SKU code, and transmit it to the POS terminal, either by deleting the serial number for second code types or sending the entire code for first code types, allowing for flexible operation modes based on user input or device commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional reader transmits the entire code data including serial number to the external device, then the code reading function is simple, but the external device cannot process the data efficiently when serial number is not required
Solution Approach 1:
The reader extracts and transmits only the necessary portion of code data (SKU code) to the external device, separating the essential identification information from the serial number. This extraction principle resolves the contradiction by improving data processing efficiency while maintaining simple reader functionality through automated selective transmission.
Solution Approach 2:
The code data is segmented into distinct components (SKU code and serial number), allowing the reader to identify and transmit only the relevant SKU code portion. This segmentation enables efficient external device processing without requiring complex manual intervention to separate necessary from unnecessary data.
2Adaptability or versatility
If the reader deletes the serial number and transmits only the SKU code, then the data transmission is optimized for external device processing, but the reader cannot handle cases where the external device requires the complete code format
Solution Approach 1:
The reader implements dynamic operation modes that can switch between transmitting complete code data and transmitting only extracted SKU codes. This dynamic adaptability allows the system to adjust its transmission behavior based on external device requirements, achieving code format compatibility while managing operational complexity through predefined mode settings.
Solution Approach 2:
The reader is designed with multi-functionality to handle both complete code transmission and extracted SKU code transmission. This universal capability allows the same device to serve different external device requirements without requiring separate specialized readers, achieving adaptability while consolidating functionality.
3Ease of operation
If the reader always transmits the complete code data, then the operation is simple and consistent, but external devices must be adjusted to handle mixed code formats including unnecessary serial numbers
Solution Approach 1:
The reader extracts and transmits only the relevant SKU code information, removing unnecessary serial number data. This extraction improves information relevance by ensuring that transmitted data contains only what is needed for external device processing, while maintaining ease of operation through automated extraction without requiring manual data selection.
Data Source
AI summary
According to one embodiment, a code reader includes an interface, a scanner, and a processor. The interface transmits and receives data to and from an external device. The scanner reads a code from an item. The processor extracts a portion of code information obtained from the code read by the scanner and transmits the portion of the code information to the external device through the interface.
