About an inch thick and the size of ruler - it's a portable scanner.

The VuPoint Solution Magic Wand Portable Scanner lets you scan documents, photos, receipts, etc. anywhere and save them on a Micro SD card. You choose between 300 x 300 dpi standard resolution and 600 x 600 dpi high resolution. You copy in color or black and white (monochrome). Setting up the Magic Wand is very easy. Insert the batteries, which are included, scan the white sheet of paper (also included) until the green light goes out to indicate the device is calibrated. Then starting scanning. Outside of being a little lopsided, because I didn’t scan in a straight line, my first scan was really good. This is a perfect, inexpensive device that will let you turn stacks of documents into organized digital files. Scan just the portion of a book you need. Or a recipe from a cookbook. It features a Contact Image Sensor, scanning status LCD display and Optical Character Recognition software. Scan speed is about 13 seconds for high resolution with color and 3 for standard with color. Your speed may vary. The Magic Wand supports Micro SD cards up to 32GB (card not included). Works with Windows / Mac OS 10.4 or above. The kit includes USB cable, software, carrying pouch and 2 AA batteries. Although there are a few other mini portable scanners on the market, this one does an excellent jou and  retails for less than $100. Available on the web, or at Bed, Bath & Beyond. $99.99.
