A supermarket named E.Leclerc in Saint-Jean-du-Falga in France has pasted a total of about 30,000 electronic shelf labels, which can quickly change the price of goods, greatly saving labor and improving work efficiency. Electronic shelf labels are provided by Altierre.
In March of this year, the Saint-Jean-du-Falga supermarket installed an electronic shelf label system (ESL), using RFID technology to manage product prices. After the system is put into use, commodity prices can be updated automatically.
The supermarket’s RFID tags, readers, data processing software, and system integration services are all provided by Altierre, a technology company headquartered in San Jose, California. The data processing software links Altierre’s main server with the supermarket’s back-end management system.
Supermarkets often hold promotional activities, commodity prices change frequently, and manual price changes are time-consuming and laborious. Supermarket management departments have been searching for convenient solutions. Some products need to be stored in a low-temperature environment, and supermarkets need solutions that can use active tags at -20 degrees.
The solution includes a 2.4GHz RFID tag (provided by Altierre, using an air interface protocol) connected to an electronic display. Altierre also provides two access points to collect all tag data in the store.
The active tag chip not only stores product information such as tag codes, prices, and categories, but also includes some animations and texts. In addition, the tag includes an internal clock that can store the price that will change within a period of time, which is mainly used when the power is off.
Association of goods and shelf labels: Use handheld devices to scan the barcodes of the goods and electronic shelf labels (the code is associated with the RFID code of the shelf labels), and send this information to the back-end management system of the supermarket via a WiFi connection. The supermarket management department formulates a price change plan in the management system, and sends the price information to the access point through the wired network, and the access point sends the label information to the shelf label. The shelf label receives the price information from the access point, displays it on the LCD screen, and sends a response signal to the access point at the same time, indicating that the label has received the information. If no response signal is returned, the access point will send a warning to the background management system that the tag is damaged or missing, so as to supervise the tag and ensure the normal operation of the system.
In addition, the system also has a product recall function. The label is associated with the storage unit (SKU) of the product, and the corresponding recall reminder will be displayed on the LCD screen of the expired product for the staff to remove the shelf.
In addition to providing electronic shelf labels, Altierre produces smart temperature sensors embedded with RFID tags, designed to help retailers track low temperature or products that have strict temperature requirements. In order to better manage the quality of commodities in low-temperature environments, supermarkets plan to adopt this kind of smart temperature sensor. The sensor is not restricted by the environment and can send and receive signals in a low temperature environment.
E.Leclerc is a large French supermarket chain with 550 stores in China and 100 branches in Spain, Portugal, Poland, Italy and Slovenia. Whether the electronic shelf label system will be implemented in other chain stores is still a mystery.

The electronic shelf label system is an electronic display device that can be placed on the shelf and can replace traditional paper price tags. Each electronic shelf label is connected to the computer database of the mall through a wired or wireless network, and the latest commodity prices are passed through the electronic shelf The screen on the label is displayed. In fact, the electronic shelf label successfully incorporated the shelf into the computer program, got rid of the situation of manually changing the price label, and realized the price consistency between the cash register and the shelf.
A complete set of electronic shelf label system consists of four parts: main computer PC, EPD screen, electronic label electronic shelf label and smart handheld terminal equipment. First, the product information in the database is encoded by the host computer through the electronic shelf label system application software, and then the price and other information that needs to be updated are transmitted to the exciter through the Ethernet (or serial communication port); the exciter drives the loop antenna to load The RF radio signal with product data information is sent to the entire store (the loop antenna here is usually arranged on the ceiling of the store to surround the entire store building, limiting the coverage of the RF wireless signal to a specific enclosed space); electronic label electronic shelf The tags are wireless data receivers with identification codes. They can restore the received RF signals to valid digital signals and display them. The electronic shelf label system has two communication functions: point-to-point and group sending, namely: the host computer is both You can transmit data to a specified tag, or you can control all tags at once. Each electronic shelf label stores multiple pieces of information about the corresponding product, and salespersons can conveniently check and check with the help of smart handheld terminal equipment.
The shelf label is placed in a special PVC guide rail (the guide rail is fixed on the shelf), and it can also be set as a suspended or dedicated structure. The electronic shelf label system also supports remote control, and the headquarters can uniformly mark the price management of the commodities of its chain branches through the network.
