POS System Automatic Receipt Issuance via Payment Code Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current point-of-sale (POS) systems require store clerks to manually ask customers if they want a receipt, making the process cumbersome for both parties.
Innovation Solution
A POS system that includes a user terminal capable of generating and displaying a payment code and setting for receipt issuance, using a scanner, printer, and processor to automatically determine and control receipt issuance based on customer settings encoded in the payment code.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a store clerk manually asks a customer whether they need a receipt, then the customer's receipt preference can be confirmed, but the transaction process becomes cumbersome and time-consuming for both parties
Solution Approach 1:
The system performs preliminary action by having customers pre-register their receipt preferences and store this information in advance. When a transaction occurs, the POS terminal automatically retrieves and applies the stored preference without requiring manual inquiry, thus resolving the contradiction between reliable preference confirmation and ease of operation
Solution Approach 2:
The system implements feedback by continuously storing and updating customer receipt preferences from previous interactions. This feedback mechanism allows the system to automatically adapt to customer preferences in subsequent transactions, eliminating the need for repeated manual inquiries while ensuring accurate preference confirmation
2Productivity
If a POS system automatically issues receipts based on pre-stored customer preferences, then the transaction process becomes efficient and streamlined, but the system requires additional functionality to store and manage customer preference data
Solution Approach 1:
The system merges the preference management functionality with the existing POS terminal and payment processing system. By integrating preference storage and retrieval into the current infrastructure rather than adding separate systems, the solution achieves automatic preference-based receipt issuance while minimizing the increase in device complexity
Solution Approach 2:
The POS terminal is designed with multi-functionality, serving both as a transaction processing device and a customer preference management system. This universal approach allows the same device to handle both traditional POS functions and the new preference storage/retrieval operations, thereby improving productivity without proportionally increasing device complexity

AI summary
A point-of-sale (POS) system includes a user terminal configured to generate and display a symbol that represents a payment code that can be used for payment in a sales transaction and a setting related to issuance of a receipt; and a POS terminal including a scanner, a printer, and a processor configured to: register one or more items for purchase, decode a symbol read by the scanner to obtain a payment code and a setting, execute payment processing for the items that have been registered for purchase using the payment code obtained by decoding the symbol, after the payment processing is executed, determine whether to issue a receipt based on the setting obtained by decoding the symbol, and upon determining to issue a receipt, control the printer to issue a receipt for the purchased items.
