Electronic Shelf Label Systems for Retail Stores

Electronic shelf label systems for retail stores allow prices, promotional content and product details to be updated centrally and displayed on digital screens throughout the store.

From electronics and cosmetics to home improvement, fashion and homeware, modern retail stores often manage large product catalogues and frequent promotional campaigns.

Paper labels must be reprinted whenever information changes. Electronic shelf labels allow the same display to be updated repeatedly, making them suitable for retail environments that require more flexible and consistent product communication.

What Is an Electronic Shelf Label System for Retail Stores?

A retail electronic shelf label is a digital e-paper screen installed on shelves, display stands, hanging rails or product areas.

Depending on the label model and store requirements, the screen may display:

• Product name
• Model or variation
• Current price
• Previous price
• Promotional price
• Discount percentage
• Technical specifications
• Colour or size options
• Barcode or QR code
• Stock information
• Warranty period
• Energy rating
• Campaign end date

Electronic shelf labels can therefore support more than price presentation. They can also provide selected information that helps customers compare products and make purchasing decisions.

How Do Electronic Shelf Labels Work in Retail Stores?

1. Product information is transferred to the platform

Prices, product codes, campaign details and technical information are entered into the central ESL management software.

The data may be obtained from:

• ERP software
• POS systems
• E-commerce platforms
• Product information management systems
• Central campaign management tools

2. Labels are paired with products

Each electronic label is associated with the relevant SKU or product code.

When a product is moved or replaced, the label can be paired with another item.

3. Store templates are created

Retailers may prepare different layouts for:

• Standard pricing
• New-season products
• Limited-time campaigns
• Clearance items
• Member prices
• Technical product information
• Low-stock products

4. Updates are transmitted through the gateway

Changes are sent wirelessly to a single label, a product group, a selected branch or several store locations.

5. Delivery status is monitored

The management platform can confirm whether the updated content has reached the relevant label.

In multi-store operations, central teams may monitor campaigns and pricing across different branches from the same platform.

Vycall Tip: Do not treat an electronic shelf label as a screen that displays only a price. Use the available space to present one or two key product features that genuinely help customers make a decision.

Benefits of Electronic Shelf Labels for Retail Stores

Centralised price and campaign management

Campaigns prepared at head office can be distributed to selected branches through a controlled digital process.

This helps retailers apply the same campaign dates, prices and design structure across multiple stores.

Support for online and in-store consistency

When e-commerce and physical store information are managed through compatible data sources, consistency between channels can be improved.

Correct product codes and campaign rules remain essential for successful synchronisation.

Better product comparison

In categories such as electronics, home improvement and homeware, customers often need more than a price.

Electronic labels may display information such as:

• Screen size
• Storage capacity
• Energy consumption
• Product dimensions
• Material type
• Warranty period
• Package quantity
• Size or colour

Stronger promotional visibility

Old price, new price, discount percentage and campaign duration can be displayed through a dedicated promotional template.

Colour-supported e-paper screens can make selected promotional areas more noticeable.

Reduced label replacement workload

Employees do not need to print and replace a physical label after every price change.

The operational benefit becomes more significant as the number of products and branches increases.

A standardised retail presentation

The same typography, price hierarchy and campaign structure can be applied across all departments and locations.

Retail Store ESL Use Case

Consider a consumer electronics retailer operating ten branches and preparing a weekend campaign.

Prices for selected televisions, headphones and small appliances are scheduled to change on Friday evening and return to standard levels on Monday morning.

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

1. The central team prepares the promotional product list.
2. Discounted prices and campaign dates are reviewed.
3. A promotional template is assigned to the products.
4. Updated information is sent to the relevant labels in selected branches.
5. Store managers confirm the updates.
6. Standard prices are restored when the campaign ends.

This structure supports a more controlled campaign process. Its success still depends on accurate product data, stable communication infrastructure and clearly defined approval responsibilities.

Which Types of Retail Stores Can Use Electronic Shelf Labels?

Electronics stores

Labels may display model, storage capacity, screen size, warranty and energy information.

Cosmetics stores

Product volume, promotional price, discount percentage and short descriptions can be presented.

Home improvement stores

Dimensions, material type, unit price, package quantity and stock codes may be displayed.

Home and lifestyle stores

Product dimensions, colour options, set contents and promotional information can be managed.

Pet stores

Product type, package size, age group and price can be displayed clearly.

Sports stores

Model, available sizes, colour options and campaign information may be included.

Fashion stores

Labels may display size, colour, product model and price.

The selected mounting accessories should be compatible with shelves, rails, hangers or display stands.

What Should Retail Stores Consider When Selecting an ESL System?

Product volume and campaign frequency

The operational value of centralised management generally increases as the number of products, branches and price changes grows.

Screen size

A compact screen may be sufficient for products that only require a price.

Larger labels may be more appropriate for technical products, promotional displays or items requiring several specifications.

Integration structure

Product codes must be consistent across ERP, POS and e-commerce systems.

Using different codes for the same item across multiple platforms can make integration more complex.

Mounting accessories

Different solutions may be required for:

• Standard shelf rails
• Hanging displays
• Glass surfaces
• Tabletop stands
• Product demonstration areas
• Clothing rails

Store lighting

Labels should be tested under real in-store lighting before the final model and template are approved.

User permissions

Head office and branch employees should be assigned appropriate access rights.

Pricing, campaign and template permissions can be separated according to role.

Technical support

Retailers should evaluate support for:

• Initial installation
• Software updates
• Battery management
• Label replacement
• Integration maintenance
• New branch expansion
• Gateway configuration

Vycall Tip: Select label sizes according to information density. Compact labels are suitable for standard pricing, while larger screens are more effective for technical details and prominent campaigns.

Frequently Asked Questions

Can QR codes be displayed on electronic labels?

Yes, when the label resolution and template design are suitable. QR codes should be tested with different smartphones under real store lighting.

Can multiple stores be managed from the same platform?

Yes. A compatible management structure can support central control of several branches with separate permissions for stores, departments and users.

Are electronic labels used only for displaying prices?

No. They may also display technical specifications, promotional dates, barcodes, QR codes, stock status and short product information.

Are ESL systems suitable for small retail stores?

Suitability is not determined only by store size. Product volume, campaign frequency, employee workload and pricing complexity should be evaluated together.
