It can be a challenge to keep track of loose papers when you're traveling on a business trip. The Doxie portable scanner, which weighs less than a pound, can scan business cards, photos, and letter-sized documents. The device can scan a document in color in 12 seconds at 600 DPI and turn it into a PDF, JPEG or PNG file. You also can scan directly to the cloud, sending the document straight to web apps like Google Docs, Acrobat, Evernote, and Flickr, and assigning a short URL to the digital document for easy file sharing. The device connects to either a PC or Mac with a USB cable.
