The price tag system of the present invention has the advantages of reliability, easy to install and low cost. Using the system of the invention, the prices can be easily updated even from a remote location. In addition, if there is one defective panel, the defective panel can be easily removed and replaced without any changes made to the base structure, which also greatly reduces the operation costs.
