NFC Self-Checkout System for Retail Settlement Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current self-checkout solutions in physical stores face challenges such as high labor costs, long waiting times, and high commodity theft rates due to complex operations and high renovation costs, especially during peak shopping periods.
Innovation Solution
A method utilizing NFC technology for efficient self-checkout services, where a computing device reads electronic tags to obtain product information, generates orders, and transmits settlement files to a server for verification based on user credit scores, simplifying user operations and reducing costs by minimizing the need for extensive renovations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If code scanning is performed by users manually, then settlement can be completed without cashiers, but operation complexity increases and customer experience degrades
Solution Approach 1:
The patent replaces manual code scanning operations with NFC (Near Field Communication) technology. Users simply need to tap their smartphone against the NFC reader at the checkout, and the system automatically retrieves product information from electronic tags. This substitutes the mechanical action of manually scanning barcodes with a wireless communication-based automatic identification system, significantly reducing operational complexity while maintaining automation.
2Productivity
If RFID tags are used for product recognition, then automatic settlement is enabled, but supply chain renovation costs increase
Solution Approach 1:
The patent employs NFC electronic tags instead of RFID tags for product identification. These NFC tags are significantly cheaper than RFID tags and do not require complex supply chain integration. The system achieves automatic product recognition by reading information from these low-cost NFC tags when users tap their phones, enabling efficient settlement without the high renovation costs associated with RFID infrastructure.
3Extent of automation
If extensive sensors are deployed throughout the store for automatic recognition, then self-service settlement is achieved, but renovation costs and promotion threshold increase
Solution Approach 1:
The patent extracts the core functionality of product identification from complex sensor systems and implements it through a simplified NFC-based approach. Instead of deploying extensive cameras, weight sensors, and other detection devices throughout the store, the system uses only NFC readers at the checkout point combined with NFC tags on products. This extraction of the essential identification function dramatically reduces renovation requirements while maintaining self-service settlement capability.
4Reliability
If credit score verification is implemented, then theft prevention is enhanced, but system complexity increases
Solution Approach 1:
The patent introduces a credit score verification mechanism that acts as an intermediary layer between the settlement system and theft prevention. The system automatically checks the user's credit score through NFC communication and uses this information to determine the level of verification needed. This intermediary approach enables effective theft prevention by leveraging existing credit assessment data, avoiding the need for complex surveillance and manual inspection systems.

Data Source
AI summary
The specification describes methods and systems for processing information. An exemplary method includes reading, by a computing device through a near field communication (NFC) interface, an electronic tag to obtain product information stored in the electronic tag; storing, by the computing device, the product information in the computing device; generating, by the computing device, an order based on the stored product information; receiving, by the computing device, a settlement file after the order is paid, wherein the settlement file comprises a user identification (ID) and a user credit score corresponding to the user ID; and transmitting, by the computing device, the settlement file to a server for verification based on the user credit score.
