Overview
Not a feeder-tray scanner, this Brother DS-640 takes one sheet at a time and draws power from a laptop or PC over its micro USB cable. Included software scans to File, Image, OCR, Email and cloud services.
Light weight, a wide choice of operating systems and card handling make it flexible for work away from a desk. The limit is the single-sheet feed, which makes long documents a manual job.
Who it's for
People who scan receipts, contracts and ID cards on the road, with a laptop in hand, will carry it everywhere. Desk-based offices with paper stacks should choose a feeder model instead.
Pros and cons

Performance notes
Scan speed is rated on letter paper at the listed resolution, and each sheet goes in separately. Included OCR turns scans into editable files. Automatic color detection, bleed through prevention and background removal clean pages as they are captured.
