A device for remotely displaying prices of multiple goods displayed on a display stand using a wireless transceiver and a controller is provided to control information for the prices and stock of the multiple goods displayed on the display stand in a remote place by using one wireless transceiver, and prevent absence of the goods on the display stand by calling a staff before the absence of the goods. Multiple display parts(600a-600c) display the price of the goods displayed on the display stand. A memory(550) stores price information and goods information corresponding to the display parts. The controller(520) manages the price information and the goods information stored in the memory, and makes the corresponding display part to display the price information stored in the memory. An interface(530) modulates/demodulates data of the controller through a specified communication mode. The display part includes the interface modulating/demodulating data of the controller, a display unit displaying the price information stored in the memory, and an enable signal detector connecting the display unit and the controller by detecting an enable signal transmitted from the controller.
