E-Books Utilize High-Tech ‘Ink And Paper’ Technology : NPR.
excerpt:
Part of what’s making digital readers like the Amazon Kindle and the Sony Reader popular is that they’re easy to read. The technology that makes that possible, basically a digital version of ink and paper, is now being added to other electronic accessories.
For many of these devices, a Massachusetts company called E Ink is behind that technology. It aims to marry the readability and attractiveness of traditional print materials with the changeability of electronics. E Ink is also making displays for cell phone keypads that can morph from numbers to letters, wristwatch faces that can change content, and a credit card anti-fraud device that could constantly change the security code on the back of the card.
