The Dazzle ZiO! Hi-Speed Portable Reader/Writer is designed for people on the go who have digital cameras or other digital devices like MP3 players, mobile phones and PDAs that use digital media. Your ZiO HS Reader/Writer addresses the two most important needs for mobile professionals, durability and speed. When you flip your ZiO HS Reader/Writer into the open position, the sleek and lightweight device can be connected directly to your computer's USB port for digital media access or can be connected with a supplied USB cable. When flipped into the closed position, the ZiO HS Reader/Writer covers both an inserted digital media card and the USB connector, turning the device into a durable yet highly portable digital media carrying case.
