This is the portable, cordless handheld scanner that preserves important documents, letters, or recipes, recording its contents onto a memory card for later retrieval on your computer. As you move the scanner over an area as large as 8 1/2" H x 50" L, its sensitive color image sensor scans at high (600 dpi) or standard (300 dpi) resolution, saving images as JPEG files stored on an inserted microSD card (sold below). A scan of a passport takes only five seconds. You can download your images to your computer using the included USB cable. Its built-in display shows the selected resolution, remaining battery life, and memory status. Two included AA batteries provide up to 180 scans. It can support microSD cards as large as 32 GB. Works with Windows 7, Vista, XP, or Mac. 10" L x 1 1/4" W x 1" H (7 1/2 oz.)
