time2025/04/01
- Sertag introduces the e-paper phone case, a revolutionary NFC-powered, no-battery smartphone case that allows users to customize and update their phone case design anytime, anywhere.
In an era of digital customization, why settle for a static phone case when you can have one that changes at will? Sertag introduces the e-paper phone case, a revolutionary NFC-powered, no-battery smartphone case that allows users to customize and update their phone case design anytime, anywhere.
Sertag's e-paper phone case features a four-color electronic ink display (black, white, red, and yellow), offering a unique, paper-like appearance with no glare and ultra-low power consumption. Unlike traditional LCD or OLED displays, e-paper technology ensures a natural, eye-friendly viewing experience.
Designed for a wide range of users, our e-paper phone case is compatible with iPhone, Samsung, and Huawei smartphones equipped with NFC functionality.
No Battery, No Charging – Powered by NFC
Forget about wires, charging, and battery concerns. This passive NFC e-paper phone case operates without a built-in battery, drawing power directly from your smartphone’s NFC signal. Simply place your phone on the case and use the dedicated app to refresh the display.
How It Works
