The Inkcase Plus is a new secondary screen for the iPhone 5, Samsung Galaxy S4, Samsung Note. It connects to the back and allows you to reap the benefits of dedicated e-readers like the Kindle. It has just passed FCC certification and will be available to purchase for $79.
The InkCase eReader features a 3.5 inch, 360 x 600 pixel grayscale ePaper display which is visible in direct sunlight without a backlight. The low-power screen also only uses electricity when you refresh the page, so it should get up to 5 days of battery life from the device’s 400mAh battery. One of the cool things is you can attach it to your phone or read independently, which actually makes it a dedicated e-reader.
So how does this contraption actually work? You have to connect it up to your phone via Bluetooth. This allows you to download specific apps and use it on the secondary display. So if you want to read eBooks, you need EpiReader. In order to attach it to your phone, you need a pouch or Fitcase Plus.
