What Is an Electronic Shelf Label, How Does It Work?
What's actually happening behind the system that's replacing paper labels
in stores? From its components to the price-update process, and from the
technologies it uses to in-store installation, we break down electronic

01 · The Basics
What Is an Electronic Shelf Label (ESL)?
An electronic shelf label (ESL) is a wireless system that replaces paper
price tags on store shelves, displaying product prices and information on
digital screens. Connected to central software, the labels update
automatically whenever a product's price changes, with no manual
intervention needed.
In short, ESL is an automation system that eliminates the need to walk the
aisles and swap labels every time a price changes.
02 · System Components
What Parts Make Up the System?
An ESL system isn't a single product — it's made up of several components
that work together, each responsible for a different stage of the process.
E-ink labels
Digital screens mounted on shelves that display product price and information.
Base station (transmitter)
The central device installed in-store that communicates wirelessly with the labels.
Management software
The central panel where prices are entered, labels are monitored, and ERP/POS integration happens.
03 · How It Works
How Does a Price Change Reach the Shelf?
The process follows a simpler logic than it might seem: when a product's
price changes in your ERP or POS system, that data is automatically sent to
the ESL management software. The software identifies the relevant label and
sends the new data to the base station, which then transmits it wirelessly
directly to that label. The label updates its display with the new data,
and the whole process completes within seconds.
Hundreds or even thousands of labels can be updated simultaneously from a
single central point — no need for staff to walk the shelves one by one.
04 · The Technology Behind It
The Technologies That Make This Possible
E-ink (electronic ink)
Paper-like, readable display technology that only uses power when the content changes.
Wireless communication protocols
Low-power radio frequency that handles data exchange between the label and the base station.
ERP/POS integration
Automatic connection with the sales and inventory management systems that are the source of price data.
Cloud-based management panel
An interface for remotely monitoring and managing all labels, from a single store to multiple branches.

Frequently Asked Questions
No, the labels are wireless and run on an internal battery — no cable
connection is required.
A change made in your ERP/POS system is transmitted to the relevant
label within seconds via the base station.
This depends on the hardware used and the size of your store; the
system is sized correctly based on your store layout.
Integration is possible with most ERP/POS/CRM systems; your existing
infrastructure is assessed before installation.
