As Wikipedia says, electronic paper is a display technology designed to mimic the appearance of regular ink on paper. Electronic paper reflects light like ordinary paper and is capable of holding its display without power, requiring it only to change the display.

The technology has been used limitedly for various things and is now coming into the mainstream. The E-Ink Corporation is responsible for many applications of this technology thus far, including the Lexar 2 GB JumpDrive Mercury JDMC2GB-431 or the Lexar 1 GB JumpDrive Mercury JDMC1GB-431. The Jumpdrive Mercury uses an electronic paper display from E-Ink to display an exterior usage gauge on the drive. Since it draws no power, the gauge is always visible.

While E-books as well as low-power informational displays are the most popular of the expected usage of this technology, it is definitely worth monitoring. For now, its use on the Jumpdrive makes us endorse the Mercury should you wish this feature. We will be reviewing USB drives and purchase considerations in a future article.
