Price Tag Transmission Method
Mobile Communication
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.
Access Point Communication
For a larger number of electronic tags, the access point 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
Here's an example scenario: Imagine every city's marathon finish line equipped with an access point. As marathon enthusiasts wearing this card approach the finish, the content on the card gets updated, displaying your personal information and race results. You can then upload this image to a mobile app, turning it into a fun conversation piece with your friends. Wouldn't this make for an unforgettable marathon experience? If you're looking to create something similar, please contact us — we have ready-made solutions available.
