  • Lacks ADF and support for single-pass, two-sided scanning
  • No bundled app for business-card archiving

The economical Brother DSmobile DS-640 scans quickly and accurately, but it lacks single-pass duplex scanning, making it an occasional-use model for thrifty shoppers.

A couple of steps down from the Editors’ Choice DSmobile DS-940DW and a step down from the DS-740D, the Brother DSmobile DS-640 ($109.99) is a manual-feed portable document scanner designed for use on the road in conjunction with a laptop PC. However, for the $20 list-price difference between it and the DS-740D, you give up automatic two-sided scanning and a few other features, not to mention the ton of options you would get by stepping up to the PCMag favorite DS-940DW (which lists for $70 more than the DS-640). Even so, if all you need is to scan short one- or two-page documents to a laptop or desktop, the DS-640 does that relatively quickly and with respectable accuracy.
