Table Payment Terminal Reassignment via Dynamic QR Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing table payment systems require QR codes to be installed at specific desks and stores, limiting their reuse across different tables and locations, making it difficult to accommodate changes in table layouts or operator transitions.
Innovation Solution
A table payment system utilizing a parent terminal, multiple child terminals, and information storage media that can wirelessly communicate in a power-saving manner, managed by a server capable of associating and changing correspondence information, allowing flexible deployment and reuse across tables and stores.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If QR code is installed at specific desk and store, then payment function is enabled at that location, but the QR code cannot be reused at other desks or stores
Solution Approach 1:
The system divides the payment terminal into two independent components: a QR code (information storage medium) and a child terminal (processing device). The QR code contains only identification information and can be independently printed and attached to any table, while the child terminal contains the payment processing logic. This segmentation allows the QR code to be freely relocated without affecting the terminal's functionality, enabling easy reuse across different tables and stores.
Solution Approach 2:
The child terminal is designed as a universal device that can serve multiple tables and stores. Instead of having dedicated terminals for each specific location, a single child terminal can be associated with multiple QR codes through the management server. This allows one terminal to handle payments at various locations by simply changing its association with different QR code identification information, achieving multi-functionality and reusability.
2Adaptability or versatility
If QR code contains specific desk and store information, then payment is enabled at that location, but the system cannot accommodate layout changes or operator transitions
Solution Approach 1:
The system implements dynamic associability where the relationship between QR codes and child terminals is not fixed but can be changed at any time through the management server. When table layouts change or operators transition, the management server simply updates the association data to reflect new configurations. This dynamic nature eliminates the need for physical reconfiguration or system reinstallation, allowing rapid adaptation to changes without time loss.
3Ease of operation
If multiple QR codes are installed for different tables, then each table has payment capability, but management and reassignment becomes difficult
Solution Approach 1:
The management server acts as an intermediary that centralizes the management of all QR codes and child terminals. Instead of manually managing each terminal individually, the management server maintains a database of all QR code identification information and their associations with child terminals. This centralized management allows operators to easily reassign terminals to different tables by simply updating the association data in the server, greatly simplifying the management process even when multiple terminals are involved.

AI summary
The table payment system comprises a parent terminal, a plurality of child terminals capable of wirelessly communicating with the parent terminal in a power saving manner, a plurality of information storage media installed on a table together with the child terminal, and a management server capable of communicating with the parent terminal and user terminal via a network and comprising a storage device. Each of sets of the child terminal and the information storage medium a is installed on each of the plurality of tables. The management server stores management information in the storage device, the management information including multiple pieces of correspondence information in which child terminal identification information, information storage medium identification information, related information are associated with each other. The management server is capable of changing an association of the correspondence information.
