Choose Your Perfect Solution: 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

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.

Substitute for Paper Usage

Epaper provide a paper-like touch and reading experience, serving as a sustainable alternative to traditional paper and reducing environmental impact from deforestation and paper manufacturing.
 

Device Packaging
95% of this device's packaging is crafted from wood fiber-based materials sourced responsibly from managed forests or recycled sources.
