Checkout System Link Module for Parallel Data Input and Payment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In semi-self-type checkout systems, customers wait unnecessarily for data input to be completed by store clerks before they can initiate payment preparation, leading to inefficient use of time and resources.
Innovation Solution
A checkout system that enables communication and data transfer between registration and checkout apparatuses before and during data input, allowing customers to start payment preparation at the checkout apparatus without waiting for data input termination, through a link module, display module, and settlement module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the customer waits for data input to be completed by the store clerk before initiating payment preparation, then the data accuracy is ensured, but the customer waiting time increases
Solution Approach 1:
The system performs preliminary actions by enabling the checkout apparatus to display commodity information and prepare payment interfaces before the registration apparatus completes data input. The link module establishes communication in advance, allowing the checkout apparatus to pre-load transaction details and prepare payment options, thus reducing customer waiting time while ensuring data accuracy through subsequent confirmation.
Solution Approach 2:
The system implements feedback mechanisms where the checkout apparatus receives real-time status information from the registration apparatus through the link module. This allows the checkout apparatus to update its display and payment preparation status based on the actual data input progress, ensuring that payment is only finalized when data input is complete while providing customers with visible progress feedback.
2Productivity
If the customer starts payment preparation after moving to the checkout apparatus, then the checkout process is streamlined, but unnecessary waiting time occurs before data input is terminated
Solution Approach 1:
The system ensures continuity of useful action by allowing the checkout apparatus to continuously prepare payment interfaces and display commodity information even while the registration apparatus is still completing data input. The link module maintains continuous communication between the two apparatuses, ensuring that payment preparation activities proceed without interruption and can be immediately finalized once data input completes.
3Loss of time
If the registration apparatus and checkout apparatus communicate before and during data input, then customer waiting time is reduced, but system complexity increases
Solution Approach 1:
The system introduces a link module as an intermediary component that facilitates communication between the registration apparatus and checkout apparatus. This modular intermediary handles the complexity of inter-apparatus communication, data synchronization, and status updates, thereby reducing customer waiting time while containing system complexity within a dedicated communication module rather than distributing it throughout the entire system.
Data Source
AI summary
In a checkout system, a registration apparatus is set to be capable of executing data communication with any one of a plurality of checkout apparatuses before data input of a commodity purchased by a customer at the registration apparatus is started or during a period from the start to the termination thereof. Details of the commodity of which the data is input in the registration apparatus capable of executing data communication with any one of the checkout apparatuses capable of executing the data communication are displayed on a display of the corresponding checkout apparatus before the data input of all commodities purchased by the customer is terminated. Settlement is executed based on input payment data at any one of the checkout apparatuses capable of executing the data communication if the data input of all the commodities purchased by the customer in the registration apparatus is terminated.
