Cart-Mounted POS Terminal Dual Scanner Registration Cancellation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cart-mounted point of sales (POS) systems require complex operations for canceling commodity registrations, which is a barrier for users seeking simpler methods.
Innovation Solution
The system incorporates a POS terminal with a registration scanner and a cancelation scanner on a shopping cart, allowing users to register and cancel commodities by scanning barcodes, with the virtual POS server managing the registration and cancelation processes through a network connection, enabling straightforward data transmission and updates.

Engineering Contradiction Analysis
1Ease of operation
If a touch panel is used for cancelation operations, then the system can perform cancelation functions, but the operation becomes relatively complicated
Solution Approach 1:
The scanner functionality is segmented into two distinct types: a first scanner for registration operations and a second scanner for cancelation operations. This segmentation allows each scanner to be optimized for its specific function, with the second scanner specifically designed to automatically perform cancelation by simply scanning the barcode, thereby simplifying the cancelation operation while maintaining system functionality.
Solution Approach 2:
The second scanner enables automatic cancelation operation without requiring user interaction with the touch panel. When the user scans a barcode with the second scanner, the system automatically identifies and cancels the corresponding registration, making the system serve itself by automatically performing the cancelation function without complex manual operations.
2Ease of operation
If a first scanner and second scanner are provided, then registration and cancelation can be performed by simple scanning operations, but the device complexity increases
Solution Approach 1:
Both the first scanner and second scanner utilize the same barcode scanning technology and interface with the same POS terminal system. The scanners are designed to be universally compatible with the existing touch panel and processing system, allowing them to perform their specific functions (registration and cancelation respectively) without requiring entirely separate systems, thereby limiting the increase in overall device complexity.
Solution Approach 2:
The POS terminal acts as an intermediary between the scanners and the touch panel operations. Instead of requiring direct complex interactions, the POS terminal receives barcode data from either scanner and automatically translates it into the appropriate registration or cancelation command, simplifying the interface between the scanning devices and the system's operational commands.
Data Source
AI summary
A point of sales (POS) system includes a server configured to store a list of commodities registered for purchase in association with identification information about a customer and a terminal comprising first and second scanners through which a commodity code is read. The terminal is configured to acquire identification information, upon reading of a commodity code through the first scanner, transmit first data including the commodity code and the identification information to the server, and upon reading of a commodity code through the second scanner, transmit second data including the commodity code and the identification information to the server. The server is configured to, upon receipt of the first data, register the commodity having the commodity code in the first data in the list, and upon receipt of the second data, delete the commodity having the commodity code in the second data from the list.
