The second generation of Sony's Digital Paper (model DPT-RP1) has a high-resolution display, a more responsive touch panel, precise handwritten note-taking capabilities and wireless document transfer to a PC or MAC.

Digital Paper is a document reading and note-taking tool designed for professors, researchers or students in varied science and technology disciplines.

The device is based on a 13.3 inch (1650 x 2200 dots) E Ink Mobius display, which uses flexible TFT technology. The screen displays full-size views of 8.5-by 11-inch documents so users can avoid scrolling or zooming to read a full page.

The Digital Paper has a 16GB internal memory, its 0.23 inches thin and weighs 12.3 ounces, about the weight of 60 pieces of letter-sized paper. It enables up to 3 weeks use on a single charge using rechargeable lithium-ion batteries.

The Digital Paper companion app on a PC or Mac allows two-way transfer of single or multiple files to and from Digital Paper via Bluetooth, Wi-Fi or USB. It also enables auto sync and document sharing from widely used document management services such as Dropbox, Box and Google Docs. The "Print to Digital Paper" function lets users print from any Microsoft Word, Excel, PowerPoint, or PDF document. Select Digital Paper as the printer option and send from a Windows 10 PC or Mac to Digital Paper via Bluetooth, Wi-Fi or USB.
