What are Electronic Shelf Label tags?

Price Tags, also known as Electronic Shelf Labels (ESL), are small wireless smart display devices that can display specific product information and price on the shelves. It’s integrated with POS, CRM or ERP systems, to ensure reliable product pricing and information. It can also be used for displaying a patient’s name on a hospital, or an attendee’s name on tradeshow, or even the ID and stock of a product on a warehouse’s shelf. Many different applications for such a small display!

Alongside the rising trend of automation and digital stores, electronic shelf labels are more and more adopted by all kinds of retail stores, including supermarkets, specialty stores, business centres, hospitals and warehouses.

The tags management software manages the data of product information, which are sent to the base station via wireless network. Once the information is transmitted to the base station, it will then be sent to the terminal display to update the price labels based on the information inputted into the label management software. A communication network allows the price, or other information, display to be automatically updated whenever a product info is changed. This communication network is the true differentiation and what really makes the ESL solution a smart viable solution. The wireless communication must support reasonable range, speed of update, battery life, accuracy and reliability.

Our ESL solution

Our solution is all about connecting stores and on-line, about the moment the consumers is choosing the product, during the buyer’s journey, on this omnichannel experience, where he can check the product’s information, and even interact with the electronic shelf labeling, and the brand can be trully digital, effective and creative.

How do Electronic Shelf Tags work?

The solution includes a base station that connects, through Wi-Fi or BLE, the ESL tags, and to a cloud server through Wi-Fi, where the data is retrieved from, which is integrated with a 3rd-party system, an ERP, POS or CRM.

Sizes and temperatures

Price tags, typically called that because they are labels to display the price of products. offer a long range of working temperatures, from -25° to approximatelly 40°C, with several display dimensions: 1,54” 2,13” 2,66” 2,7” 2,9” 3,7” 4,2” 5,8” 7,5” 11,6”.

The majority of ESL tags use Liquid Crystal Display (LCD) type of screens, but Full Graphic E-Paper and Segmented E-Paper can also be found.

The connection between the base station and the ESL tags is usually by Wi-Fi, but BLE can also used, and between the base station and the cloud server is through internet.

3r-party integration is possible for data exchange, to fetch the latest information, prices, names, and so on. It’s very easy to use the API to connect to any ERP, CRM, POS or other management system.

Some ESL tags have NFC. They are true smart digital tags, which give an interesting opportunity to able the consumer to “touch” the electronic tags and trigger some marketing campaign. For digital tags without NFC, a QR code can be used for the same purpose.

Speed of updating ESL tags

8 tags per second with 1 base station, faster if with more base stations.

One base station can handle around 5000 tags, but for better speed, between 3000 and 4000 is suggested.


Depending on the model and size of each tag, colors may vary between: black-white, black-white-red (or yellow) and 8-color. The bigger the display size, the more colors may have.
