Smartphone APP or Gateway Version
Smartphone APP Version
When using a small number of electronic tags, you don't need cloud servers, ESL management systems, or access points—just a single Android smartphone is sufficient to easily update prices and give your store a modern, sophisticated appearance.
Gateway Version
For a larger number of electronic tags, the gateway allows for centralized management and remote updates. This setup reduces maintenance costs, saves time, and enhances the store's overall image.

We aim to make electronic shelf labels more than just price displays
No longer just a simple price tag in supermarkets, it now doubles as an advertising POP machine. By utilizing the screen's blinking effect, it grabs customers' attention. What's more, it allows you to edit advertising messages online. Unlike traditional POP machines that can only display fixed messages, now you have the freedom to display whatever you want.
