Duplex scanning: Being able to scan both sides of a two-sided document in a single pass drastically reduces the amount of time it takes to scan large documents.Being able to run your scanner without a USB cable is a nice perk, especially if the scanning speed isn’t any slower. Wi-Fi: Just a few years ago, Wi-Fi was a rarity in portable document scanners.Ideally, a good scanner accurately recognizes every character, but realistically we expect a success rate of above 90%. The best portable document scanners can also export the text as an editable document, either in DOC, RTF, or TXT format. OCR: A good portable document scanner should be able to accurately recognize printed text via optical character recognition, or OCR, and turn it into a searchable PDF.The hardware interface needs to be easy to navigate, and the desktop and mobile software should be powerful enough to get the job done but not so complex that it gets in your way when you’re working under pressure. Usability: If you hate using your scanner, you’re not going to use it.

Stationary desktop scanners are faster, but they take up more space on a desk, and you can’t easily toss them in a drawer until the next time you need them.
