Overview
Brother builds the DS-940DW as a compact scanner that works wirelessly or over USB, capturing both sides of a page in one pass. The scan lid doubles as a space saver, and files can go to mobile devices through the free iPrint&Scan app.
Wireless scanning to phones and cloud destinations frees it from a laptop. The limits are extra purchases and downloads: the micro SD slot needs its own card, and drivers and software come from the web.
Who it's for
Mobile professionals and small offices that scan receipts, forms and ID cards, and want to do it from a phone, fit this scanner. Large batch scanning calls for a feeder model.

- Wireless and USB connections
- Two-sided scanning in one pass

Performance notes
