Reinkstone's new 4-color e-ink cases reinvent phone coverage by integrating vibrant colors into a display that is wirelessly powered by the phone itself through NFC technology.
With negligible power consumption and an easy-to-update interface via a companion app, these cases transform dull phone covers into dynamic, interactive presentations.
The e-ink display serves practical uses such as displaying photos, to-do lists, boarding passes, or QR codes, enhancing phone functionality without replacing the main screen.
This innovative case allows updates in real-time, raising questions about why such vibrant, functional solutions weren't developed sooner in the smartphone accessories market.
