Electronic Shelf Label
An Electronic Shelf Label (ESL) is a digital price tag that uses electronic displays, typically e-ink or LCD, to show product information on retail store shelves. ESLs are connected to a central system that allows retailers to update prices, promotions, or product details remotely and instantly, without the need for manual label replacement. This technology improves pricing accuracy, reduces labor costs, and enables dynamic pricing strategies, enhancing the shopping experience and operational efficiency in retail environments.
An Electronic Shelf Label (ESL) diagram typically illustrates the components and workflow of an ESL system. The main elements include:
1. Central Server: Stores and manages product information, prices, and updates.
2. Communication Network: Connects the server to ESLs through a wireless protocol (e.g., Wi-Fi, Bluetooth, or proprietary RF).
3. **ESL Devices**: Digital display tags attached to store shelves, showing updated product data.
4. **Store Management Interface**: Software used by store staff to control and monitor ESLs, update prices, and manage promotions.
The diagram usually shows the flow of data from the central server to the ESLs via the network, highlighting real-time updates and easy control over product labels across the store. This visual helps explain how the system automates pricing, reduces errors, and supports dynamic pricing models.
