4 inch E-ink Name Badge Bluetooth 4 Color E-Paper Name badges

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.

Using 2.4G Bluetooth communication, the e-ink name badge can update employee information, visitor credentials, or event details wirelessly through a mobile device or management system. Compared with traditional printed ID cards, this e-ink smart badge allows organizations to display employee photos, names, titles, QR codes, and barcodes dynamically. It makes identity presentation more dynamic, digital, and sustainable.

With wireless charging and long battery life, the e-ink name badge provides a sustainable and flexible identity solution for digital workplaces, smart offices, conferences, and exhibitions.

The 4 color e-ink display enhances visual recognition and allows organizations to display branding elements, department colors, or alert information more clearly.

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.
