RFID Tag State Modification for Self-Service Checkout Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-service checkout and rental processes in supermarkets and libraries are inefficient due to the need for specific devices to scan bar codes and degauss tags, leading to user queuing and potential security concerns when users use terminals other than specific self-service devices for checkout or rental verification.
Innovation Solution
An information processing method that involves scanning an identification code on an offline item using a terminal, determining the RFID tag's identification, and modifying its state to indicate successful checkout or rental, allowing the item to pass anti-theft verification without the need for specific self-service devices, using a RFID writer to set the RFID tag to a preset signal or invalid state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If specific self-service devices are used to scan bar codes and degauss tags, then checkout verification can be performed, but user queuing occurs and efficiency decreases
Solution Approach 1:
The patent enables multiple types of terminals (mobile phones, tablets, computers) to perform checkout verification functions that were previously limited to specific self-service devices. The system accepts various terminal devices and processes checkout requests from any of them, making the checkout function universal across different device types, thereby eliminating the need for users to queue at specific self-service devices.
Solution Approach 2:
The patent implements a self-service checkout system where users can independently complete the checkout process using their own terminals. The system automatically verifies item information, processes payments, and modifies RFID tags without requiring assistance from staff or interaction with specialized equipment, enabling users to serve themselves and reducing queuing time.
2Ease of operation
If users use terminals other than specific self-service devices for checkout verification, then device accessibility improves, but security verification becomes unreliable
Solution Approach 1:
The patent replaces the mechanical/barcode scanning system with an RFID (Radio Frequency Identification) system. Instead of physically scanning bar codes with specific devices, the system uses RFID tags and readers that can communicate wirelessly. This substitution allows any terminal with RFID capability to perform verification, improving accessibility while maintaining reliability through the more advanced RFID technology.
Solution Approach 2:
The patent changes the verification parameter from optical barcode recognition to electromagnetic RFID signal detection. By modifying the fundamental detection mechanism from visual scanning to radio frequency communication, the system enables broader terminal compatibility while enhancing verification reliability through RFID's inherent security features and data integrity capabilities.
3Measurement precision
If bar code scanning and tag degaussing are performed at self-service devices, then item verification is achieved, but the process requires specific equipment and user queuing
Solution Approach 1:
The patent extracts the verification function from specialized self-service devices and integrates it into general-purpose terminals. By separating the RFID tag modification capability from the terminal device itself and implementing it on the server side, the system allows any terminal to perform verification without requiring built-in scanning or degaussing hardware, thereby reducing device complexity requirements.
Solution Approach 2:
The patent introduces an RFID tag as an intermediary carrier that bridges the item and the terminal system. Instead of requiring terminals to directly scan or interact with items through complex mechanisms, the RFID tag serves as a mediator that stores item information and can be remotely modified by the server, simplifying the interaction between terminals and items while maintaining verification accuracy.
