Description

TECHNICAL FIELD [0001] The present invention relates to an electronic price display system and a method for displaying an electronic price based on a wireless network,

The present invention relates to an electronic price display system, and more particularly, to an electronic price display system comprising a BLE-based electronic price indicator system, a beacon-based advertisement solution, and an NFC interworking-based additional information providing apparatus, The present invention relates to a system and method for displaying a fusion wireless electronic network based on a Bluetooth wireless network, which can increase the efficiency of a store management by reducing work and price error burden.

Typically, in a retail store, paper labels are used to display product information such as sale price or discount information, unit price, and country of origin for products on shelves. In the price display method using the paper label, when the product information is changed or the product display position is changed, the paper label which is in use has to be discarded and a new paper label has to be created. Therefore, maintenance costs are incurred constantly. Waste paper is wasted, which has a negative impact on environmental protection.

Therefore, research and development of an electronic price indicator (or an electronic shelf label (ESL)) as a means for replacing a conventional paper label is actively carried out.

The electronic price indicator is disposed on a shelf of a retail store and displays various price information through a display means such as an LCD. When the information of the product being displayed is changed or the display position of the product is changed, There is an advantage that it can be repeatedly used by updating the information of the product.

On the other hand, in recent years, an electronic price indicator has been required not only to display price information but also to display merchandise information in addition to Store Symbol, Promotion Image, and Barcode.

Particularly, the commodity information may be a price of a commodity, a name of a commodity, a price, a usage method, a quantity, an origin, an advertisement, etc. If the commodity is a food, the commodity information may include a recipe, .

In addition, when it is necessary to update the price information immediately on the spot as well as the confirmation of the product information, it is inconvenient because it is impossible to transmit the price to the ESL through the server.

Also, since such conventional ESL systems do not have advertising or coupon promotion functions, there is no opportunity to provide a new and interesting shopping experience to customers in a convergent manner.

In addition, since the conventional ESL system unilaterally displays the price received from the server, there is no way to check the price of the merchandise one by one, and there is a problem that the display price and the registration price of the counter do not match.
