The Role of Electronic Shelf Labels in Grocery Stores

The Role of Electronic Shelf Labels in Grocery Stores 

Grocery store aisles play an integral role in the customer in-store experience. Electronic shelf labels (or ESLs) uplevel store pricing operations and allow customers and associates to have more seamless day-to-day interactions. In fact, Walmart says it plans to replace traditional paper tags with electronic shelf labels (ESLs) in all 4,600+ U.S. stores by the end of 2026. [1] 

Vusion - recognized as a Representative Vendor in the 2024 "Gartner Market Guide for Smart Shelf in the Retail Store" [2] - provides solutions that integrate seamlessly with electronic shelf labels for grocery stores. These solutions allow retailers to quickly manage price updates, launch promotions with precision, and monitor shelf activity to optimize performance and operational efficiency.

How Do Digital Price Tags Work in Grocery Stores? 

Digital supermarket shelf labels, also known as ESL systems, consist of three main elements: 

1. The tags themselves, i.e., electronic price labels 
2. The ERP (Enterprise Resource Planning) system, or back-office server 
3. The communication infrastructure 

These three components work together to create a connected pricing ecosystem. Electronic Shelf Labels (ESLs) integrate with a retailer's existing ERP, POS, and inventory management systems through a cloud-connected platform. When pricing or product information is updated in the back-office system, the change is automatically synchronized to the corresponding shelf labels through the store's communication infrastructure. This seamless integration helps ensure consistent information across shelves and checkout while reducing manual processes and improving operational efficiency. 

Retailers gain centralized control over pricing, inventory management, customer relationship management, and additional operational functions through a single platform. 

The labels are available in multiple formats and sizes. They utilize e-ink displays for optimal battery life while featuring full-color labels. Vusion's has a wide portfolio of electronic price tags for supermarkets. 

Product, pricing, and operational information is managed through a centralized, cloud-connected platform that integrates with existing retail systems. Updates are securely synchronized to electronic shelf labels across the store, helping ensure consistent information at the shelf edge and checkout. Designed for long-term performance, Vusion's ESLs use ultra-low-energy display technology to deliver long-lasting battery performance, with lifespan varying by model, usage, and operating conditions.  

What Are the Operational Benefits of Electronic Shelf Labels? 

Esls in supermarkets bring measurable gains in operational excellence including improved associate workflows and better inventory management.  

Grocery retail moves fast, changing as items circulate and merchandising plans are reworked to accommodate new prices and new promotions that require constant updating. Digital shelf label systems allow retailers to monitor store activity with greater accuracy while reducing operational costs and minimizing manual effort. Retailers can oversee price updates across all departments. 

Walmart reports that manually changing 120,000 paper price labels per store took two days. [5] With digital price tags, the same update takes minutes. Retailers can then focus on higher-value tasks like shelf replenishment and customer service. You also avoid shelf-to-register mismatches, which helps you prevent fines and protect your price image. 

Whether retailers need electronic shelf labels for fruit and vegetable electronic labels, pharmacy shelf labels, or anything in between, Vusion's electronic shelf labels offer specific fixtures designed to accommodate retailers' requirements. Digital grocery store price labels can adjust to any situation, providing clear, accurate, and visually appealing information for shoppers. From adjustable viewing angles to full display rotation, these labels are designed to deliver maximum versatility. 

Digital shelf label systems provide greater control over merchandising and ROI strategies while ensuring only authorized users can access your electronic shelf labels. Labels can be fixed in place using Vusion's patented Easylock Anti-Theft System. 

Electronic shelf labels enable supermarkets to leverage automation, artificial intelligence, and deep-learning. Low-value-added and routine tasks can be automated while pricing actions benefit from capabilities fed by in-store data. Retailers can achieve store operational excellence by automating these repetitive processes. 

Replacing paper labels also cuts waste through agile product management: shelf capacity and stock-level alerts, promotions, and coupons. Retailers can eliminate pricing errors, improve price image and customer confidence, avoid regulatory fines, and use seamless omnichannel synchronization to grow sales and margins. 

Beyond Pricing: Supermarket Digital Signage as Retail Intelligence 

Electronic shelf labels can do far more than communicate pricing information. They also help create a richer and more interactive shopping experience. 

A full-color ESL can level it up by creating a colorful, lively space for additional product information, promotional details, and interactive elements that provide a more immersive shopping experience. These features help shoppers make more informed decisions while creating a more engaging retail environment. 

From adjustable viewing angles to full rotation, the display is built for flexibility in any retail environment. Its fluid design makes it easy to adapt to different shelf layouts and product types while keeping information clear and visible for shoppers. 

Supermarket digital signage also displays rich content on labels: allergen information, sustainability scores, product comparisons, and customer reviews. NFC-enabled labels let shoppers access detailed product information instantly via a simple smartphone tap. 

ESL systems are just one part of a broad transformation that is taking place across grocery retail in the digital era. Complementary solutions can provide even deeper insights and enhanced customer intelligence. 

For example, Vusion’s Retail Intelligence Software solution uses AI-driven analytics to combine aisle activity, POS data and third-party information sources. The platform then analyzes that data to generate recommendations that help retailers optimize operations, reduce waste and improve profitability. Each label becomes a sensor, a data point feeding data-driven commerce solutions and predictive retail performance. Shelf data enables decisions before problems impact sales, transitioning retail from reactive to predictive. 

IoT Cloud Platform: The Leading ESL Tag Solution for Supermarkets and Grocers 

The IoT Cloud Platform solution is designed to simplify and automate your in-store operations, helping you achieve optimal efficiency and reduced labor costs. The system's ESLs can be adapted for any store section and feature high-resolution color e-paper displays with a super-wide viewing angle. With long-lasting battery performance, the labels help make pricing automation seamless and efficient. 

The IoT Cloud Platform is the result of Vusion's 30-year expertise in ultra-low power wireless IoT device management. The IoT Cloud Platform OS relies on unmatched technology. Constantly upgraded and updated to bring you the highest level of performance, security, and future-proofing, it forms a reliable backbone for digitized stores. 

Physical retail is at a turning point where customers expect an experience that preserves the appeal of in-person shopping while drawing from the convenience and transparency of digital approaches. Digital grocery store shelf labels bridge the gap between two worlds, creating scenarios where shoppers enjoy high-quality information about the products and feel more connected to the store itself. All that without having to forego Search, Reviews, and other perks the Internet age has gotten them used to.
