Electronic shelf labels (ESLs) represent a significant advancement in retail technology, transforming how retailers manage pricing, inventory, and customer interactions. Pioneered by innovative companies like Lidl, which has implemented ESLs across its UK stores, this technology is becoming an essential tool for modern retail operations. Lidl GB successfully trialled electronic ESLs in over 35 UK stores, resulting in an estimated annual saving of 206 tonnes of carbon through reduced paper and packaging while also drastically minimising ink usage. Remarkably, over two-thirds of shoppers surveyed did not notice the subtle change, demonstrating how seamlessly this modern technology can be integrated without impacting the shopping experience.

What are electronic shelf labels?
Electronic shelf labels are digital display devices used in retail stores to show product pricing and other information. Controlled centrally, these labels replace traditional paper price tags, offering real-time updates and greater efficiency. Typically, ESLs are connected via wireless networks, allowing for instantaneous price changes and information updates from a central database or control system.
These labels use e-ink technology, similar to that found in e-readers, which provides clear and readable displays with minimal power consumption. Through a combination of access points and software portals, store managers can update prices, promotions, and product information across multiple stores or departments simultaneously, ensuring accuracy and consistency.
The development of electronic shelf labelling technology
The second generation of ESLs emerged in the early 2000s, bringing improved technology and greater reliability. These systems featured better wireless connectivity and began to utilise e-ink displays, which offered clearer and more energy-efficient visual outputs. The user interface and control systems also became more sophisticated, allowing for more seamless integration with store management systems.
How do electronic shelf labels work?
Electronic shelf labels operate through a combination of hardware and software components. At the heart of each ESL is an e-ink display, which provides high visibility and low power consumption. These displays are connected to a central control system via wireless access points distributed throughout the store. The access points communicate with the ESLs, sending updates and changes as needed.
The control system is typically a web portal that allows store managers to manage pricing, promotions, and product information centrally. This web portal integrates with the store’s existing inventory and pricing systems, ensuring that all information is accurate and up-to-date. Through this portal, managers can schedule price changes, run promotions, and adjust product information across multiple locations, all from a single interface.
ESLs are designed to operate in a wide range of environmental conditions, making them versatile for various retail settings. Standard ESLs can function efficiently in temperatures ranging from 0 degrees Celsius (refrigeration temperature) to 40 degrees Celsius (room temperature). Additionally, specialised ESLs are available for more extreme conditions, such as freezer environments, where they can function in temperatures as low as -25 degrees Celsius. This adaptability ensures that ESLs can be used throughout the entire store, including in areas requiring specific temperature controls, such as refrigerated and frozen goods sections.
The benefits of electronic shelf labels
Deliver an improved customer experience
One of the most significant benefits of ESLs is the enhancement of the customer experience. With real-time price updates, customers can trust that the prices they see are accurate and up-to-date, reducing confusion and improving satisfaction. Additionally, ESLs can display detailed product information, helping customers make informed purchasing decisions.
Facilitate dynamic pricing
ESLs enable dynamic pricing strategies, allowing retailers to adjust prices in response to market conditions, competitor pricing, and stock levels. This flexibility can help retailers optimise sales and margins, adapting quickly to changes in demand and supply.
Reduce costs to your business
Enable smart shopping and personalised advertising
ESLs can enhance the shopping experience through personalised advertising and smart shopping features. By integrating with customer loyalty programs and shopping apps, ESLs can display personalised offers and promotions, encouraging higher engagement and increased sales.
Achieve more advanced inventory management
Optimise your approach to omnichannel retail
ESLs support omnichannel retail strategies by ensuring consistency between online and in-store pricing. This synchronisation is crucial for providing a seamless shopping experience, where customers can trust that the prices they see online match those in the physical store.

How to implement electronic shelf labelling
Step 1: Define your goals
Start by identifying what you want to achieve with ESLs. Whether it’s improving pricing accuracy, enhancing customer experience, or optimising inventory management, having clear goals will guide the implementation process.
Step 2: Assess your needs
Evaluate your site’s specific needs. Consider factors such as site size, number of products, and the types of environments (e.g., room temperature, refrigeration, or freezer) where ESLs will be used. This assessment will help you determine the most suitable ESL technology and features for your store.
Step 3: Choose the right technology
Based on your goals and needs assessment, select the appropriate ESL technology. Consider factors such as display type (e-ink or LCD), battery life, connectivity options, and compatibility with your existing systems.
Step 4: Plan the deployment
Develop a detailed deployment plan that outlines the steps and timeline for the implementation. This plan should include the installation of access points, integration with your inventory and pricing systems, and training for staff on how to use the new technology.
Step 5: Pilot testing
Conduct a pilot test in a small section of your site or in a few selected sites. This test will help you identify any potential issues and make necessary adjustments before a full-scale rollout.
Step 6: Full-scale implementation
Step 7: Monitor and optimise
Use cases beyond retail environments
Warehouse shelf labelling
In warehousing, ESLs can streamline operations by providing clear and accurate labelling of inventory locations. This can enhance picking efficiency, reduce errors, and improve overall warehouse management.
