What is Electronic Shelf Labels

An Electronic Shelf Label (ESL) is a digital display device used in retail environments to show product information on store shelves. It replaces traditional paper price tags or labels. These labels are typically powered by low-energy technologies, such as E-Ink technology, which allow them to display dynamic content like prices, product names, descriptions and promotions.

Key Features of ESL System:

  • Dynamic Updates: ESLs can be updated remotely in real time, allowing retailers to change prices, stock information, or promotions across the store quickly without having to manually adjust each label.
  • Energy Efficient: ESL systems use e-ink technology, which consumes very little power. The display only uses energy when the information is being changed, which makes them highly efficient.
  • Improved Accuracy: By connecting to a central system, ESLs help reduce human errors in pricing, stock updates, or other product details.
  • Enhanced Customer Experience: Customers can quickly view updated information, including current pricing, special offers, and product specifications, improving their shopping experience.
  • Design Flexibility: ESLs can vary in size, shape, and features. Some can show just the price, while others may include barcodes, QR codes, or even additional product details.

Benefits for Retailers:

  • Cost Savings: Reduces the need for printing and reprinting paper labels.
  • Operational Efficiency: Streamlines the process of updating pricing or product information storewide from a central location.
  • Enhanced Inventory Management: ESLs can integrate with inventory management systems, helping retailers track stock levels in real time.

How ESL System Works

The Electronic Shelf Label (ESL) system works by using a combination of wireless communication, display technology (E-Ink), and a central management system. Here’s how it generally operates:

  1. Centralized Control System:

The backbone of the ESL system is a centralized management software or server, often located in the store’s back office or at the retailer’s headquarters. This system is used to:

  • Manage pricing information.
  • Control updates to the labels.
  • Integrate with inventory management systems.
  • Push promotional information, discounts, and other dynamic content.
  1. Wireless Communication:

The ESLs communicate wirelessly with the central control system through technologies such as RF (radio frequency) or Wi-Fi. This wireless connection allows:

  • Real-time updates to prices and product details.
  • Communication with the central system to reflect the most accurate information.
  • Updates to be pushed to all labels in the store simultaneously or selectively.
  1. Electronic Display:

The ESLs themselves are equipped with e-ink displays, which are energy-efficient and capable of showing high-contrast text and images. These displays are typically low power, which makes them suitable for long-term operation on batteries. The ESL displays:

  • Price tags.
  • Product names and descriptions.
  • Barcodes, QR codes, or RFID for product identification.
  • Promotions or special offers.
  1. Automatic Updates:
  • When the central system receives a price change or inventory update, it sends a wireless signal to all relevant ESLs in the store.
  • The update is displayed automatically on the screen of each ESL in real time.
  • This removes the need for manual labour in adjusting price tags or signs, reducing errors, and ensuring consistent information across the store.
  1. Customer Interaction:

In some advanced ESL systems:

  • Labels can include QR codes or NFC (Near Field Communication) features that allow customers to scan them with their smartphones for additional information, reviews, or to access online pricing.
  • ESLs are equipped with color displays, which can highlight promotions, markdowns, or other offers to attract customer attention.
  1. Energy Management:
  • ESLs use e-ink displays, which are highly energy-efficient. These displays only consume power when updating the information, and once the information is displayed, the power consumption is almost negligible.
  • ESLs use low-energy wireless technology to ensure long operational life.
  1. Integration with Other Systems:

The ESL system integrates with:

  • Point of Sale (POS) systems to reflect sales, discounts, and transactions.
  • Inventory Management Systems to update stock levels automatically.
  • Product Information Management (PIM) systems to ensure consistency and accuracy of product data across all labels.

Summary of ESL System Workflow:

  • A change in price or product information is made in the central management system.
  • The system sends the update to the ESLs wirelessly.
  • ESLs update their display to reflect the new information (price, product details, etc.).
  • Customers see the updated information in real-time on the shelf.

The entire system is designed to improve accuracy, save time, reduce operational costs, and provide a better customer experience by automating and streamlining the labelling process in retail environments.

Benefits of ESL System

The Electronic Shelf Label system offers several significant benefits for retailers, enhancing both operational efficiency and the customer experience. Here are the key advantages:

  1. Improved Operational Efficiency
  • Real-time Updates: ESLs can be updated instantly across the entire store (or multiple locations) from a central control system. This eliminates the need for manual changes, saving time and reducing labour costs.
  • Automated Price Adjustments: Price changes or promotions can be pushed to all labels simultaneously, ensuring that prices are always consistent across the store, preventing pricing errors.
  1. Cost Savings
  • Reduction in Paper and Printing Costs: ESLs eliminate the need for printing and reprinting paper tags, which can be expensive and wasteful, especially during frequent price changes or promotions.
  • Lower Labor Costs: Staff no longer need to manually update price tags across the store, which frees up time for other tasks and reduces labour costs.
  1. Accuracy and Consistency
  • Reduced Human Errors: With automatic updates, ESLs ensure accurate pricing and product information, minimizing human errors associated with manual tagging.
  • Consistency Across Locations: For retailers with multiple stores, ESLs ensure that the same price or information is displayed across all locations without discrepancies.
  1. Enhanced Customer Experience
  • Up-to-date Information: ESLs provide customers with accurate, real-time pricing and product details, ensuring they always see the latest information, including special offers and discounts.
  • Interactive Features: Some ESL systems include QR codes or NFC capabilities that allow customers to scan labels for additional product details, reviews, or online offers, improving engagement and customer satisfaction.
  1. Energy Efficiency
  • Low Power Consumption: ESLs are powered by e-ink technology, which is extremely energy-efficient. The display uses power only when updating the information, allowing the labels to last a long time on minimal battery power.
  1. Flexibility and Customization
  • Dynamic Content: ESLs can display a wide range of information such as product descriptions, nutritional facts, barcodes, and promotional messages, all of which can be changed on-demand.
