Abstract
Disclosed herein is an electronic shelf label system. The electronic shelf label system includes a wired/wireless converter wirelessly transmitting product information according to request of a server, at least one rail installed on a product display stand and including a plurality of electrical wirings, at least one first electronic tag installed in the rail and performing wireless communication with the wired/wireless converter, and a plurality of second electronic tags each installed in the rail and performing wired communication with the first electronic tag through the electronic wirings. The electronic shelf label system uses the hybrid communication in which wire and wireless are mixed, thereby making it possible to provide the smooth communication environment by removing a shadow area of communication while dispersing communication traffic.
