Abstract: Provided is an electronic shelf label system capable of shortening a period of time required in distributing a large amount of information such as update information for all electronic shelf labels. In the electronic shelf label system, a communication control device (200) distributes shelf label information for an electronic shelf label. A relay station device (300a, 300b) has an electronic shelf label allocated thereto as a relay destination of the shelf label information, and relays only a piece of the shelf label information for the electronic shelf label device that is allocated to the relay station device. The electronic shelf label receives the shelf label information relayed by the relay station device (300a, 300b), to thereby perform display based on the shelf label information.

Abstract: Provided are an electronic shelf label system, a product price management device, a portable terminal device, an electronic shelf label device, a product price management method, a product price update method, a product price management program, and a product price update program, which are capable of changing display of an electronic shelf label in a place where the electronic shelf label is installed. A handy terminal (105) reads, from a shelf label (104), identification information of the shelf label (104), and transmits, to a communication controller (102), price information of a product that is input to the handy terminal (105) itself and the identification information of the shelf label (104).
