1. Product introduction

ifLabelelectronic shelf label solution (ESL) helps you to save time with automatic price updates. It's more cost-efficient than paper, and improves your customers' experience with accurate, reliable pricing.

1.1 What is the ESL?

ESL represents Electronic Shelf Label, which is an electronic label that can be installed onthe shelf. It is a label with a E-Paper display for item display, instead of the traditional paperdisplay.The information on the screen is transmitted from the server, the screen displayitems such as product’s name, price, logo, bar code, production area, etc. The ESL system can be managed and maintained easily by an operator in a specific area of the market. Youmay manage the product information on the ESL via the terminal control system on acomputer, the ESL will update in real time as the update start.

1.2 How does the ESL system work?

The ESL system consisted of input device, host computer, router device, Access

Processor(AP) device and ESL tag device.

Step one, the user needs to input information for product into thedatabase server, either by manual input or scanner device.

Step two, the server will givecommand and information to various Access Processor(AP) set in the market or warehouse, eachAP controls a group of ESLs, the AP will transmit the information from theserver to each every ESLs via RF.

Last step, each ESL will receive information and send afeedback message to AP and eventually to the server. If the feedback is correct, ESLwill finally update its new item information, if failed, the server will alarm and prompt toupdate again.

2. System structure and configuration

2.1 The system’s structure

The entire system can be divided into three parts, which is frontal display, server dataprocessing & command control; and wireless communication.

(1) Frontal display

This part is mainly about display item information onto ESL.

(2) Server data processing & command control

Mainly two functions. Record data sent for ESL display, eventually for storage management;one is record the commodities’ information into the store management system; Commandand update information to ESL.

(3) Wireless communication

We transmit data mainly via wireless communication, when the control system send acommand to update product information, it is first send to router, then to APby WIFI or Ethernet cable,and finally transmit to each ESL tag by RF.
