What is ESL? Link to heading

Electronic Shelf Labels (ESL), also known as digital shelf labels or electronic price tags, are small battery-powered displays mounted on store shelves. They replace traditional paper price tags and allow retailers to update prices, promotions, and product information instantly and remotely from a central system.

These labels typically use electronic paper (e-paper) technology that mimics printed paper with excellent readability and minimal power use. Advanced models support color, graphics, QR codes, or basic interactivity.

A typical ESL system includes the labels, wireless gateways, and central management software integrated with the retailer’s POS or ERP systems.

How It Works Link to heading

  1. Data Integration — Pricing changes are made in the central software.
  2. Wireless Transmission — Commands are sent via gateways using low-power wireless protocols (Bluetooth, proprietary RF, etc.).
  3. Instant Update — ESL tags receive the signal and refresh their e-paper display.
  4. Verification — The system confirms successful updates for price integrity.

E-paper ensures the display stays visible without continuous power, enabling long battery life. Updates can be applied store-wide or targeted in seconds.
