ESL Uses and Technology in Retail
How Electronic Shelf Labels Work
Electronic shelf label systems form the backbone of modern retail technology. These systems use a combination of hardware and software to automate price updates and product information across thousands of products. A centralized label management platform allows retail staff to configure pricing, assign labels, and monitor inventory in real time. The system packages product data and transmits it wirelessly—often using radio frequency, Wi-Fi, or Bluetooth Low Energy—to each ESL device on the shelf.
Tip: Wireless protocols like RF and BLE ensure stable, long-range connections, making them ideal for large retail environments.
Each electronic shelf label features a display panel, typically using e-ink for low power consumption and high readability. Some models use LCD for vibrant displays, supporting dynamic content and animation. Power sources include lithium coin cell batteries, rechargeable batteries, or even solar panels for eco-friendly operation. Mounting hardware such as magnetic mounts or adhesive strips secures the labels to shelves. Security features like data encryption and restricted access protect pricing data from unauthorized changes.
