2.9 inch Price Tag Series
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.
Gateway Version
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.
