Key Details
Check Compatibility Before You Buy
The Brother DS-640 has the largest buyer base of any scanner in this review, with solid feedback overall, but its feedback is weaker than for the desktop ADF options here. It is a portable, single-sheet scanner, so check that your operating system, Mac or Windows, is on Brother's supported list before buying.
For straightforward scanning on the road, the DS-640 delivers on portability. The USB-powered design and laptop-bag-compatible form factor make it genuinely convenient for travel scanning. Confirm your computer and operating system are on Brother's supported list before purchasing.

Bottom Line
