Description

Technical Field

[0001] This invention relates to the field of electronic price tag technology, and more particularly to an intelligent electronic price tag system. Background Technology

[0002] Electronic price tags are electronic display devices used in retail settings such as supermarkets, convenience stores, and pharmacies to display product prices, replacing traditional paper tags. In the retail industry, replacing traditional paper price tags in a supermarket requires staff to print, cut, and insert each tag individually—a time-consuming and labor-intensive process. Manually replacing traditional paper tags is prone to errors, potentially leading to discrepancies between the "tag price" and the "checkout price." Furthermore, traditional paper price tags cannot be updated in real time, easily causing price discrepancies between online and in-store pricing, resulting in customer complaints.
