Dedicated access point
ESL
PDA(including smartphone with NFC)

System Construct

1.Software Platform
Connecting with the existing system, synchronizing the basic commodity information and the price information, then sending the update data to the store's AP, automatically after the data update is completed, and finally confirming the success of each update.

2.ESL(Electronic Shelf Label)
Displays price and basic information for each commodity.

3.PDA
Scan and update information manually.

4.AP
Modify the information over the network by using the 2.4G signal, and eventually send the modified information back to the platform to ensure the success of each transmission.

Link between ESL and commodity

►Field fast binding ESL and commodity to avoid backstage binding cumbersome and manual input errors;
►Field fast unlinking to update the shelf.

Information update principle

1、Update instruction sent to the server by PDA.
2、The server process the update information to code and sent it to the AP devices;
3、AP devices transmit the data to ESLs;
4、ESLs modify the display info and feedback to the AP devices.
5、AP devices feedback the message to the server when the modification is completed.
6、The server update the new commodity information to the ERP and POS systems;
7、The steps will continue until the infomation is successfully modified.
