The SkyPix TSN410 portable handheld scanner, unlike most other portable handheld scanner, is cordless and captures important documents, letters, photos etc directly to a supplied microSD card. Rather than sheet feeding pages, which is fine for unattached sheets, the portable USB scanner is moved over the area and its sensitive color image sensor scans at high (600dpi) or standard (300dpi) resolution, and then saves the captured images as JPEG files on the microSD card. 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. The mini portable scanner can support microSD cards as large as 32GB. Works with a Mac or Windows 7, Vista, and XP and weighs only 7.5 oz/250g.This is a truly portable handheld scanner, ideal for use when visiting clients, customers etc when a power supply is unavailable or inconvenient.
