Abstract: Embodiments of the invention provide an ESL system using a smart phone and an operating method thereof. In accordance with at least one embodiment, the operating method of an ESL system using a smart phone includes listing purchase target product items and transmitting a product purchase item list through a smart phone of a user, and receiving the product purchase item list through a gateway, searching products of purchase items, and transmitting position information of each product to the smart phone, by an ESL server. The method further includes calculating an optimal path from a current position of the smart phone to a position of each product based on the position information of each product by the smart phone, and transmitting final position information of a corresponding product to the smart phone by the ESL server, when the smart phone approaches the corresponding product of a purchase target depending on a movement of the user based on the optimal path.
