Electronic shelf labels (ESLs) are evolving beyond their established role as digital price displays. As retailers connect more store systems, devices and workflows, ESLs are becoming part of a broader digital infrastructure at the shelf edge.
The future of electronic shelf labels will therefore be shaped not only by display hardware, but also by how effectively ESL systems connect shelf communication, IoT devices, store information, associate workflows and customer-facing experiences.
From Digital Price Tags to Connected Shelf Communication
The first generation of ESL projects focused primarily on replacing printed price tags and distributing approved price changes electronically across the store. This established a more scalable foundation for shelf communication.
That core capability remains important. Large stores may manage thousands of products and frequent promotional updates, making coordinated and consistent shelf execution essential across departments and locations.
When integrated with pricing and point-of-sale systems, electronic shelf labels help maintain consistency among the price approved centrally, the information shown at the shelf and the price presented at checkout.
From Individual Labels to a Managed Retail IoT Layer
As ESL deployments expand from pilot stores to hundreds or thousands of locations, managing individual labels is no longer enough. Retailers need a platform that can coordinate devices, templates, permissions, updates and integrations across the store network.
This is where an ESL system becomes part of a managed IoT layer, connecting devices, content, permissions, updates and integrations across the store network. The retailer’s core business platforms remain the authoritative sources for approved data, while the ESL platform distributes relevant information to the shelf and reports whether updates have been completed. In this way, the platform extends retail information to connected shelf-edge devices without replacing the systems that govern it.
Hanshow’s All-Star platform illustrates this direction. It supports centralized IoT device management, system integration, ESL content templates and third-party application access. Its role extends beyond label management by helping retailers connect shelf-edge devices with established operating environments.
The long-term value of an ESL platform will depend on reliability, scalability, integration flexibility, security and the retailer’s ability to govern how approved information moves from business systems to store devices.
From Digital Displays to Greater Shelf-Level Visibility
The next stage of ESL development is not simply about delivering information to the shelf. It is about creating a clearer digital reference for what should be displayed, where products should be located and where store teams may need to take action.
Electronic shelf labels can provide this reference by linking a product, a shelf position and a device identifier. When combined with complementary technologies, the reference can contribute to a clearer view of store conditions.
For example, ESLs can display approved information and identify product locations, while cameras can help detect shelf gaps, misplaced products or differences from the intended planogram. Other sensors may provide additional signals about shelf conditions, and retail platforms can connect these events with product, pricing and task information. Associate applications can then translate verified exceptions into replenishment or checking tasks.
These technologies perform complementary functions. An ESL does not independently recognize physical product conditions, while a camera image alone does not provide a complete operational view. Useful shelf visibility depends on combining appropriate signals, reliable source data and clear operating rules.
From Shelf Visibility to Store Digital Twin
As retailers improve shelf-level visibility, they can begin building more accurate digital representations of their physical stores and the workflows operating within them.
A Store Digital Twin is a digital model of relevant store layouts, product locations, equipment, operating conditions and workflows. It can help retailers compare intended conditions with observed conditions and coordinate action across headquarters and store teams.
This matters because information about the physical store is often distributed across separate systems. A Store Digital Twin can bring relevant store, shelf and workflow signals into a shared operational view, helping teams identify differences, prioritize exceptions and coordinate responses.
Electronic shelf labels contribute to this model by establishing digital connections between products and physical shelf positions. When combined with cameras, sensors, shelf information and retail platforms, these connections can support several operational scenarios.
Picking Guidance
Product-location information and label LEDs can help guide associates during ecommerce order picking. This may reduce search time and support more consistent fulfillment, especially when product positions are maintained accurately.
Associate Task Management
Shelf exceptions can be translated into tasks such as checking a price, replenishing a product, correcting a misplaced item, or reviewing a promotional display. The ESL can help identify the location, while the task platform records assignment and completion.
Shelf Visibility
Connected systems can help identify possible out-of-shelf situations, missing labels, failed updates or planogram differences. These signals require appropriate validation because observed shelf conditions may not always match expected conditions.
Exception Management
Rather than relying only on broad, routine shelf checks, retailers can prioritize areas where the system has detected a likely issue. This supports exception-based workflows in which teams focus attention on the conditions most likely to require action.
Hanshow’s NexShelf illustrates how this approach can be implemented. The solution combines Nebular Ultra electronic shelf labels, AI-camera capabilities, positioning and platform services to support shelf visibility, exception-based workflows and Store Digital Twin applications.
A reliable Store Digital Twin depends on accurate source data, appropriate update frequency, sufficient coverage, sound model design and workflows that enable store teams to act on the information provided.
From Price Displays to Richer Shopper Communication
Electronic shelf labels are also developing as customer-facing communication points at the moment when shoppers compare products and make purchase decisions.
At the shelf edge, retailers and brands can present relevant information close to the product, including promotions, product benefits, sustainability details, recipes, comparisons and QR-enabled digital experiences.
Multicolor e-paper can provide stronger visual emphasis while maintaining the low-power characteristics associated with ESLs. Larger electronic displays and LCD shelf screens can support more visually rich content in selected departments or promotional zones.
These capabilities can contribute to in-store retail media, but commercial content should remain balanced with operational clarity and the shopper’s need to identify essential information quickly.
Price and essential product information should remain easy to recognize. A clear content hierarchy helps prevent colors, messages or promotional elements from competing for attention.
What Retailers Should Prepare for Next-Generation ESLs
Before adopting more advanced ESL capabilities, retailers should ensure that source data, system integrations, security measures and store workflows are ready to support them at scale.
1. Improve Data Quality
Product identifiers, price records, shelf locations, promotion dates and label associations need to be accurate. Digital systems can distribute poor source data as efficiently as correct data, so automation should be paired with validation and correction processes.
2. Define the Integration Architecture
Retailers should define which systems remain authoritative and how approved information will move among pricing, POS, ERP, ecommerce, ESL and other store applications and devices.
The architecture should also account for update failures, network interruptions, duplicate records, and recovery procedures.
3. Address Privacy and Security
Connected labels, cameras, sensors and cloud platforms expand the store’s technology environment. Retailers should assess device identity, authentication, encryption, access controls, software updates, data retention and third-party integration risks across the full lifecycle.
Where cameras or customer-measurement technologies are involved, privacy requirements and customer expectations should be considered from the beginning.
4. Establish Pilot KPIs
An ESL pilot should measure outcomes related to the workflows being tested. Depending on scope, retailers may track price-update completion, shelf-to-checkout discrepancies, promotion execution, label-update coordination time, device-update failures, exception-resolution time, picking time, on-shelf availability and associate task completion.
5. Evaluate Vendor Service Capabilities
Hardware specifications are only one part of a large-scale ESL program. Retailers should also evaluate integration support, deployment planning, device monitoring, security documentation, training, maintenance, local service coverage, lifecycle management and service-level agreements.
The best-fit solution will depend on store format, deployment geography, existing systems, operational maturity and the retailer’s long-term digital-store roadmap.
Connected Shelf Infrastructure: The Next Chapter for ESLs
The future of electronic shelf labels extends beyond replacing paper tags with digital displays. ESLs are becoming part of a connected shelf infrastructure that links approved information, physical locations, IoT devices, store teams and customer communication.
Not every retailer needs to adopt every capability at once. A practical approach is to establish clear operational priorities, build reliable data and integration foundations, validate results through representative pilots and expand when the next use case is justified.
