The ImageMate USB 2.0 Reader/Writer is a single slot, Hi-Speed reader and writer that connects to your computer's USB 2.0 port. Because USB 2.0 devices are backwards compatible with USB 1.1 ports, the ImageMate USB 2.0 Reader/Writer will work with all existing USB ports. The ImageMate USB 2.0 provides the ability to write data to and read data from flash memory cards without connecting your digital device (digital camera, handheld computer, digital music player, etc.) directly to a computer. SanDisk's ImageMate USB 2.0 Reader/Writer is a fast way to transfer pictures, music, and data to and from your computer.
