The electronic shelf label (ESL) tag is primarily used to display the price of a product, along with other potential information, such as the expiration date, sales offers, bar codes, QR codes, virtual codes, etc. It is typically placed in front of a product or group of products on the shelf. This provides a convenient way to manage or update product information or set dynamic pricing OTA, using either a mobile handheld reader or a static remote readers accompanied by a user-friendly application interface. This approach saves considerable time and labor costs compared to the commonly used static labels (e.g., paper labels), while also enhancing the shopping experience.

A typical ESL unit or tag is composed of several components required for communication and information display, including the RF module, microcontroller, battery, and display unit. To manage information on the ESL tag, communication occurs wirelessly between the tag and the reader, which may be a base station or a handheld reader connected to a server application.
