InkCase, An E-Ink Screen For Your iPhone

By

I saw the Oaxis InkCase at the Mobile World Congress last week, and it looks pretty neat. The v2 “case” is actually an e-ink panel that connects to the iPhone (or other device) via Bluetooth and can show anything on its e-ink screen. The new version is modular, so you can slip in into any case for any device, and even mount it, say, on the handlebars of a bike for a sunlight-friendly readout.
