Detailed
The 4 inch 4 color e-paper smart badge is designed for modern workplaces, events, and visitor management systems. With a 528 × 768 resolution 4 color E-ink display (black, white, red, yellow), the e-ink name badge enables dynamic identity presentation while maintaining ultra-low power consumption.

How Bluetooth 4 Color E-ink Name Badges Work?
Smart e-ink badges use wireless communication technology to update identity information on the display. Administrators can update badge content through a mobile application or centralized management system.
When employee information or event credentials are modified, the system sends updated data to the e-ink name badge via Bluetooth. The badge refreshes the E-ink screen and displays the new information without requiring continuous power consumption.
Because E-ink displays only consume power during refresh, the smart badge can operate for long periods while maintaining clear visibility.

Visitor and Contractor Management: Temporary visitor e-ink badges can be quickly updated with QR codes for access control and check-in systems.
Conferences and Exhibitions: Event organizers can use smart name badges to display attendee names, company logos, and branding information.
Healthcare Staff Identification: Hospitals can use e-ink name badges to display staff identity and department information clearly.
