Electronic shelf labels (ESL) are a type of digital signage that is used to display information about products on store shelves, such as product pricing, promotions, or other product-related information. ESLs have become increasingly popular in recent years due to their ability to reduce operational costs for retailers, improve inventory accuracy, and enhance the overall shopping experience for customers. In this article, we will discuss how electronic shelf labels work.
ESLs are typically composed of two main components: a display element and a communication element. The display element is typically a low-power, high-contrast electronic paper (e-paper) display that is capable of displaying text and images. The communication element consists of a wireless communication system that enables the ESL to receive and display information from a central store server.
The central store server is connected to a store’s inventory management system, which provides real-time information about product pricing, stock levels, and promotions. This information is then sent to the ESLs via a wireless communication network, which is typically based on a low-power, short-range communication protocol, such as Bluetooth Low Energy (BLE).
When a customer browses a product on a shelf, the ESL displays the relevant information about the product, such as its price, discount, or other relevant details. When the store makes changes to the product information, such as adjusting prices or promotions, the changes are automatically updated on the ESLs, ensuring that the information displayed is always accurate and up-to-date.
ESLs are often powered by small batteries that can last for up to five years, depending on the level of usage and the type of display technology used. Some ESLs are also equipped with sensors that can detect when a customer is near the product, allowing the ESL to activate and display the relevant information.
In conclusion, electronic shelf labels are a powerful tool for retailers looking to enhance the shopping experience for their customers and streamline their operations. By leveraging wireless communication and electronic display technology, ESLs can improve inventory accuracy, reduce operational costs, and provide customers with a more engaging and informative shopping experience.
