According to an embodiment of the present invention, an electronic price indicator comprises: a base substrate and five mounting units formed on the base substrate. A first antenna for receiving information from a server is mounted on the first mounting unit. A first communication module connected to the first antenna is mounted on the second mounting unit. A second antenna for receiving a management signal from a management terminal is mounted on the third mounting unit. A second communication module connected to the second antenna is selectively mounted on the fourth mounting unit. The fifth mounting unit is selectively and directly connected to any one of the second antenna and the second communication module, and provided with a low frequency (LF) circuit mounted thereon to transmit an interrupt in accordance with the management signal to the first communication module.
