The MiWand 2 PRO is a mobile scanner powered by two AA batteries. It works without a computer and also functions without software. The scanner simply glides over the surface of a document, and the image is saved on a micro-SD card. The compact device scans with up to 600 dpi in true colour. A preview function shows the images two seconds after the scan. When the scanner is attached to the feeder dock, documents are automatically pulled in and scanned.
