Electronic Shelf Label Systems for Supermarkets

Electronic shelf label systems for supermarkets enable product prices, promotional information and shelf content to be managed centrally and displayed on digital e-paper labels.

In supermarkets and grocery stores with thousands of products, manually replacing paper price tags can require significant time, labour and operational control. An electronic shelf label system allows authorised users to update selected products, product groups or entire stores through a central management platform.

The updated information is transmitted wirelessly through a gateway to the relevant electronic labels. This helps supermarkets create a more structured price management process while supporting consistency between shelf information, promotional campaigns and central product data.

What Is an Electronic Shelf Label System for Supermarkets?

A supermarket electronic shelf label system is a digital price and product information solution that displays centrally managed data on e-paper screens installed along store shelves.

Depending on the selected label model and software configuration, the screen may display:

• Product name
• Current selling price
• Previous price
• Promotional price
• Discount percentage
• Price per unit
• Product weight or volume
• Barcode or QR code
• Stock or availability information
• Campaign start and end dates
• Product origin or short descriptions

Unlike disposable paper labels, electronic shelf labels can be updated and reused without requiring a new printout for every price change.

E-paper technology also provides a paper-like appearance that remains clearly visible under typical retail lighting conditions. Because the screen mainly consumes power during an update, it can support long-term wireless use with low energy consumption.

How Does a Supermarket Electronic Shelf Label System Work?

An electronic shelf label system generally operates through five connected stages.

1. Product data is transferred to the management platform

Product names, prices, barcodes, promotional information and additional content are entered into the ESL management software.

Where technically possible, this data can also be received through integration with an existing ERP, POS or product management system.

2. Products are paired with electronic labels

Each digital shelf label is paired with the relevant product code or barcode. This pairing tells the system which product information should appear on each shelf.

3. Display templates are created

The position of the price, product name, campaign message, barcode and other fields is defined through reusable templates.

Different templates may be created for:

• Standard prices
• Weekly promotions
• Clearance products
• New products
• Member-only prices
• Limited-time offers

4. Updates are sent through the gateway

When authorised users change product information, the new data is transmitted wirelessly through the gateway to the selected labels.

Updates may be applied to a single product, a category, a specific branch or multiple supermarket locations.

5. The update status is monitored

The management platform can be used to confirm whether the new information has reached the relevant electronic label.

This allows supermarket teams to manage the update process more systematically rather than relying entirely on manual shelf inspections.

Vycall Tip: Before starting an ESL project, identify the primary source of your product and pricing data. A well-structured product database makes automated updates and label management significantly easier.

What Are the Benefits of Electronic Shelf Labels for Supermarkets?

Faster price updates

Prices can be changed centrally instead of requiring employees to locate, print and replace individual paper labels.

This is particularly valuable for supermarkets managing:

• Frequent supplier price changes
• Weekly promotional campaigns
• Seasonal offers
• Large product catalogues
• Multiple store locations

Improved shelf and checkout price consistency

When shelf labels and checkout systems receive information from the same authorised data source, price consistency can be supported more effectively.

However, the quality of this process depends on accurate integrations, correct product pairing and clearly defined approval procedures.

Reduced manual workload

Employees spend less time printing, cutting, distributing and replacing paper labels.

The time saved can be redirected towards:

• Stock control
• Shelf organisation
• Customer support
• Product replenishment
• In-store campaign implementation

More controlled promotional management

Promotional prices can be prepared in advance and scheduled for selected dates.

When a campaign ends, the label can return to its standard price template without requiring employees to manually replace every promotional tag.

A more consistent store appearance

Digital shelf labels create a standardised presentation across shelves and departments.

The same brand guidelines, price hierarchy and promotional design can be applied across multiple supermarket branches.

Reduced paper and printing requirements

The same electronic screen can be used for multiple price and campaign updates.

The actual operational savings will depend on product volume, update frequency, printing costs, staffing requirements and the scale of the installation.

Paper Price Tags vs Electronic Shelf Labels

Electronic shelf labels may not provide the same level of return for every business. A small grocery store with limited products and infrequent price changes may experience a longer investment recovery period.

For supermarkets with frequent campaigns, a high number of SKUs or several branches, the operational benefits of centralised management become more significant.

Supermarket ESL Use Case

Consider a supermarket chain operating three branches and changing the prices of several hundred promotional products every week.

With paper labels, the central team prepares a price list and sends it to each branch. Employees then print the labels, locate the relevant shelves, replace the old tags and perform a final inspection.

This process may result in:

• Missed labels
• Labels placed under the wrong products
• Outdated campaign prices
• Delays between branches
• Additional checking requirements

With an electronic shelf label system, the workflow may be organised as follows:

1. Promotional products are selected centrally.
2. New prices are entered into the ERP or ESL platform.
3. A campaign template is assigned to the products.
4. The information is sent to the relevant electronic labels.
5. Store teams confirm that the updates have been completed.
6. Standard prices are restored automatically when the promotion ends.

This scenario illustrates how the technology may be used. The final outcome will depend on system integration, product data quality, wireless coverage and operational procedures.

Where Can Electronic Shelf Labels Be Used in a Supermarket?

Fruit and vegetable departments

Labels can display unit prices, product origin, promotional information and daily price changes.

Dairy and refrigerated sections

Product name, volume, price and promotional details can be managed centrally.

Labels intended for refrigerated areas should be selected according to their supported operating temperature.

Beverages and packaged food aisles

Large product ranges and frequently changing campaigns can be controlled through a unified management structure.

Essential food departments

Unit pricing, package quantity and promotional information can help customers compare products more easily.

Promotional display areas

Larger digital labels can be used to make limited-time campaigns, multi-buy offers and featured products more visible.

What Should Supermarkets Consider When Selecting an ESL System?

Supermarkets should evaluate the entire project rather than comparing only the unit price of each label.

Important factors include:

• Total number of products and labels
• Store size and shelf layout
• Number of supermarket branches
• Gateway coverage requirements
• ERP and POS integration compatibility
• Label screen sizes
• Required colour options
• Refrigerated and frozen areas
• Mounting accessories
• Update frequency
• User authorisation
• Battery management
• Technical support
• Future expansion requirements

Vycall Tip: Begin with a pilot installation in a department where prices change frequently. A pilot project allows you to test label size, screen templates, wireless coverage and system integration before expanding to the entire supermarket.

Frequently Asked Questions

Can electronic shelf labels update prices automatically?

They can receive price updates automatically when the ESL platform is properly integrated with the authorised pricing system. The exact workflow depends on the software and approval structure used by the supermarket.

Will the displayed price disappear if the internet connection is interrupted?

E-paper labels generally retain the last displayed image. However, communication infrastructure must be available for new updates to reach the labels.

Does every product require the same label size?

No. Compact labels may be suitable for standard shelves, while larger screens may be preferred for promotional areas or products requiring more detailed information.

Does the entire supermarket need to be converted at once?

No. Supermarkets may begin with selected departments and expand the system by adding new labels and gateways over time.
