The Brother DS-640 is a compact mobile document scanner built for professionals on the move, home office workers, and small teams who need to digitize paper documents without a full-size machine.

Why this product
Pocket-sized portability
At under 11.8 inches long and 1.5 pounds, it fits easily into a laptop bag or backpack for scanning at client sites, meetings, or remote locations.
USB-powered, no wall outlet needed
Draws power from any USB 3.0 port on a laptop or PC, eliminating the need for separate power cables or wall outlets.
OCR turns paper into editable text
Included software converts scanned pages into searchable, editable Microsoft Word documents, saving time on retyping.
16 ppm speed handles typical office volume
Scans both colour and black-and-white at the same speed, keeping throughput high for small batches of documents.

- Does not support two-sided (duplex) scanning; double-sided documents require manually flipping and rescanning.
Best for
- Solo professionals and travelling consultants who need to scan receipts, contracts, and business documents without carrying a bulky device.
- Small home offices and SOHO teams processing a low to moderate volume of documents and benefiting from OCR workflow.
- Businesses managing document archival and needing to convert paper records into searchable digital files.
- Users prioritising energy efficiency; it draws just 2.6W while scanning and carries ENERGY STAR certification.
Trade-offs
- High-volume scanning: 16 ppm and single-sheet feed mean large batches take significantly longer than machines with automatic feeders.
- Double-sided documents: No duplex support forces manual page flipping and rescanning, doubling labour on two-sided originals.
- Environments without USB power: Requires a powered USB host device (laptop, desktop, powered hub); cannot stand alone at a desk.
