I remember it vividly. I was sitting in a hotel room in Manchester, the faint city hum a backdrop to my rising panic. Spread across the bed, the desk, and even the floor were dozens of receipts, invoices, signed contracts, and business cards from a three-day conference. My flight was in five hours, my expense report was due, and the thought of cramming this mountain of flimsy, easily-lost paper back into my already-stuffed briefcase was giving me a headache. I knew that some of these crucial documents would inevitably get creased, lost, or coffee-stained before I could deal with them back at the office. This chaotic ritual was a recurring nightmare for me, a constant source of stress for anyone who works on the move. The paper tiger was winning, and I needed a better weapon to fight back. This is the exact scenario where a device like the Brother DS-640 15 ppm Mobile Scanner promises to be a game-changer.

What to Consider Before Buying a Portable Document Scanner
A portable document scanner is more than just a piece of hardware; it’s a key solution for decluttering your life, streamlining your workflow, and securing your important information. In an increasingly digital world, relying on physical copies is inefficient and risky. These compact devices bridge the gap, allowing you to instantly convert physical documents—from legal contracts and financial statements to precious photos and flimsy receipts—into organized, searchable, and shareable digital files. The main benefits are profound: enhanced productivity, reduced physical storage needs, improved data security, and the peace of mind that comes from knowing your important documents are safely backed up.
The ideal customer for this type of product is the mobile professional, the frequent traveller, the small business owner, or the meticulous home archivist who despises paper clutter. If you find yourself collecting receipts in a shoebox, needing to send signed documents while out of the office, or simply wanting to digitize years of family records, a portable scanner is an invaluable tool. However, it might not be suitable for those who need to scan high volumes of double-sided documents daily. For that, a larger desktop scanner with an automatic document feeder (ADF) and duplex capabilities would be a better, albeit less portable, investment. Similarly, if your primary goal is scanning bound books, a flatbed scanner remains the superior choice.
Before investing, consider these crucial points in detail:
- Dimensions & Space: The primary appeal of a mobile scanner is its portability. Look closely at the dimensions and weight. The Brother DS-640 15 ppm Mobile Scanner, for example, measures a mere 30.1 cm in width and weighs under 500 grams, making it easy to slip into a laptop bag or even a large handbag without a second thought. Consider how and where you’ll be using it—will it live in your travel bag or sit discreetly on a small desk?
- Capacity/Performance: Performance is measured in pages per minute (ppm). A speed of 15 ppm is quite respectable for a portable unit and is more than sufficient for ad-hoc scanning tasks. Also, consider the media handling capabilities. A versatile scanner should handle standard A4 paper, but also thicker items like ID cards and business cards, as well as irregular shapes like receipts. The single-sheet feed on most portable models requires manual insertion for each page, which is a key difference from larger office scanners.
- Materials & Durability: Since this device is designed to travel, durability is key. Most portable scanners are housed in a sturdy plastic shell designed to withstand the minor bumps and scrapes of life on the road. While not as rugged as industrial equipment, the build quality should feel solid, with no flimsy parts or loose-feeling components. The internal rollers are the most critical part; they must be robust enough to grip various media types without causing jams.
- Ease of Use & Maintenance: The best portable scanner is one you’ll actually use, and that comes down to simplicity. A single USB cable for both power and data is the gold standard for convenience, eliminating the need for a separate power adapter. Software installation should be straightforward, and the scanning process intuitive. For long-term care, consider how easy it is to access the internal mechanism for cleaning dust and paper residue from the sensors and rollers.

First Impressions: Sleek, Simple, and Ready for Business
Unboxing the Brother DS-640 15 ppm Mobile Scanner was a refreshingly simple experience. The device itself is impressively compact and lightweight. At just 466 grams, it felt lighter than my morning coffee thermos. Its slim, wand-like profile immediately brings to mind its purpose: to be an unobtrusive travel companion. The build is a solid black plastic that feels durable enough for its intended use, ready to be tossed into a backpack without worry.
What we appreciated most right out of the box was the commitment to simplicity. There’s only one cable—a USB 3.0 Micro-B to Type-A—which handles both power and data transfer. This is a massive win for portability, as hunting for a spare power outlet in a busy airport lounge or client’s office is a frustration we can all do without. Inside the box, we found the scanner, the cable, a cleaning cloth, and a calibration sheet. As some users have noted, a software CD is included, which does feel a bit anachronistic in an age of ultrabooks without optical drives. Thankfully, a quick visit to Brother’s support website is all that’s needed to download the latest drivers and software suite, a process we found to be quick and painless.

- Extremely compact and lightweight, perfect for travel
- Powered directly via a single USB 3.0 cable, no AC adapter needed
- Respectable scanning speed of up to 15 pages per minute
- Versatile media handling for A4, receipts, and even plastic ID cards
Drawbacks
- Single-sheet feed can be finicky and prone to skewing paper if not fed carefully
- Included software is functional but lacks advanced multi-page editing features
A Deep Dive into the Brother DS-640’s Real-World Performance
A product’s spec sheet only tells half the story. To truly understand its value, you have to integrate it into a real-world workflow. We spent several weeks with the Brother DS-640 15 ppm Mobile Scanner, making it our primary tool for digitizing everything from multi-page reports to crumpled expense receipts. Our testing revealed a device that excels in its core mission of portability but requires a patient hand to achieve perfect results.
Design and Portability: The Road Warrior’s Dream?
There is no overstating how incredibly portable this scanner is. Its slender design (30.1 x 5.1 x 3.7 cm) means it takes up less space in a bag than a rolled-up magazine. We were able to slide it right alongside our laptop in a slim sleeve, a feat impossible with even the smallest “desktop” scanners. The weight, at under half a kilogram, is negligible. For the digital nomad, the field sales representative, or the consultant living out of a suitcase, this form factor is nothing short of revolutionary. It transforms scanning from a task you have to “get back to the office” for, into something you can do in seconds, anywhere you can open your laptop.
The single-cable operation is the killer feature that seals the deal on portability. By drawing power directly from the laptop’s USB 3.0 port, the Brother DS-640 15 ppm Mobile Scanner eliminates the need for a bulky power brick. This simplicity cannot be underrated. However, we must echo a sentiment found in user feedback: the choice of a Micro USB B 3.0 port feels dated. In a world rapidly standardizing on USB-C, it means carrying a specific cable just for the scanner. While the required cable is included, it’s one more thing to remember and a slight inconvenience compared to the universal convenience of USB-C. It’s a minor gripe but a valid one for those aiming for a minimalist, single-cable tech setup.
Scanning Performance: The Trade-off Between Speed and Precision
Brother advertises a scanning speed of up to 15 pages per minute, and in our testing, we found this to be accurate for standard, good-condition A4 documents. The scanner pulls the sheet through with confidence and produces a digital file in about four seconds. This is impressively fast for a device this small and is more than adequate for clearing a small backlog of documents quickly. We tested its versatility by feeding it a variety of media. It handled crisp A4 paper, glossy photographs, and stiff, laminated ID cards without any issue, demonstrating its robust feeding mechanism.
However, the greatest challenge with this type of scanner, confirmed by our own experience and that of several users, is the paper feed. This is not a “drop-and-go” device. It’s a single-sheet feeder that requires you to manually guide each page into the slot. As one user critically noted, it’s difficult to align the paper at a perfect 90-degree angle every time. If you’re hasty or feed the paper slightly askew, the result can be a skewed digital image or, in the worst case, a crumpled page. We found that by taking a deliberate second to square the document up to the guides before letting the rollers take over, we could achieve a straight scan nearly 100% of the time. It’s a learned skill. This makes the device less suitable for high-volume, rapid-fire scanning but perfectly fine for its intended use of deliberate, on-the-go digitization. Its scan quality is a feature that really stands out when you take the time to feed it correctly.
Image Quality and Software: Powerful Tools in a Simple Package
Once you master the paper feed, the image quality from the Brother DS-640 15 ppm Mobile Scanner is excellent. With a maximum resolution of up to 1200 dpi (interpolated), it captures fine text and intricate details with clarity. As one savvy user pointed out, setting the default scan quality to 300dpi is the sweet spot for most documents, providing a great balance of detail and file size. We also encountered the issue mentioned by another user where white pages appeared with a greyish background, but we were able to correct this easily by running the included calibration sheet and adjusting the brightness/contrast settings in the Brother iPrint&Scan software. The software is the heart of the experience.
The iPrint&Scan application for Windows and macOS is functional and straightforward. It allows you to initiate scans and easily choose your desired output, whether it’s a searchable PDF, a JPEG, or another file type. You can define workflows to automatically save scans to specific folders, cloud services (like Dropbox or Google Drive), or even open them in a specific application. This is a powerful time-saver. For instance, you can create a “Receipts” button that scans in colour at 300dpi and saves directly to your “Expenses 2024” folder. While some users found the software lacking for creating multi-page documents, we found the process to be quite simple: after scanning the first page, the software prompts you with a dialog box asking if you want to scan another page or finish the job. By clicking “scan,” you can add pages continuously until you’ve built your complete multi-page PDF. It’s not as seamless as an ADF, but it’s perfectly capable.
What Other Users Are Saying
Our findings align closely with the balanced perspective of the wider user community. Many, like one “prolific archivist,” were initially skeptical but were ultimately won over by the device’s performance, calling it a keeper after comparing it to numerous other portable models. They praise its ability to help them achieve their goal of a paperless life. This sentiment is echoed by business travellers who call it “ottimo” (excellent) and praise how it fits perfectly into a laptop bag, making it an indispensable tool for work on the road.
On the other hand, the most common and significant criticism revolves around the paper feed mechanism. One frustrated user stated that “1 in 3 pages results in the paper getting scrunched up,” a problem they attribute to the difficulty of aligning the paper perfectly. This highlights the learning curve we also experienced; the scanner demands a careful hand. Other negative feedback points to isolated quality control issues, with a few users receiving units that showed a blinking red light, indicating a paper jam where none existed, rendering the device unusable. These instances appear to be outliers but serve as a reminder that hardware failures can occur.
How Does the Brother DS-640 Compare to the Competition?
The Brother DS-640 15 ppm Mobile Scanner occupies a specific niche, but it’s important to understand the alternatives to ensure it’s the right choice for your needs.
1. Epson FastFoto FF-680W Wireless Photo Scanner
- World’s Fastest Personal Photo Scanner (1) — scan thousands of photos as fast as 1 photo per second at 300 dpi (2); batch-scan up to 36 photos at a time
- Preserve Your Priceless Photos — restore, organize, protect and share photos; scan Polaroid photos, panoramas, postcards and photos up to 8" x 10"
The Epson FastFoto FF-680W is a different beast entirely. While it can scan documents, its primary mission is high-speed photo scanning. With a robust automatic document feeder and specialized software to handle delicate photos and capture information from the back of them, it’s designed for someone looking to digitize entire albums of family memories. It’s much faster, offers wireless connectivity, and can handle batches of photos or documents effortlessly. However, it is significantly larger, heavier, and more expensive. If your main goal is archiving hundreds of photos, the Epson is the superior tool; if you need to scan a contract in a coffee shop, the Brother DS-640 is the clear winner.
2. Doxie Pro DX400 Duplex Document Scanner
- [Fast and Powerful] High quality scans of documents, invoices, statements, receipts, reports, business cards, photos, drawings, sketches, classwork, homework, and more!
- [Two-Sided Scanning] Crisp duplex scans of your two-sided paper, with features like text recognition, automatic cropping, rotation, and contrast boost. Collapsible document feeder and direct feed slot...
The Doxie Pro DX400 is a compelling desktop alternative that prioritizes features over ultimate portability. Its key advantage is automatic duplex (two-sided) scanning in a single pass, a feature the Brother DS-640 lacks. It also comes with an automatic document feeder that can handle a stack of pages, making it far more efficient for digitizing multi-page reports. While still compact for a desktop scanner, it’s not designed to be carried in a laptop bag daily. The Doxie Pro is the better choice for a home office or small business that needs efficient, unattended batch scanning and duplex capabilities but still values a small footprint.
3. C-Pen Exam Reader
- Allows students with dyslexia, or other reading difficulties, to take written exams. Bolsters reading independence
- Totally portable, pocket-sized device reads text out aloud with an English human-like digital voice
The C-Pen Exam Reader isn’t a direct competitor but represents a different type of scanning technology. This is a “pen scanner” designed to capture lines of text, not entire documents. You slide the tip over a sentence in a book or paper, and it instantly digitizes that text, and can even read it aloud. It’s an invaluable tool for students with reading difficulties or researchers who need to quickly grab quotes and citations. It cannot, however, scan an entire invoice, photo, or ID card. This is a specialized tool for text snippets, whereas the Brother DS-640 is a versatile tool for whole-document capture.
Final Verdict: The Right Tool for the Right Job
After extensive testing, we can confidently say that the Brother DS-640 15 ppm Mobile Scanner is a superb device for its intended audience. It is an exceptionally portable, convenient, and effective tool for the mobile professional, the frequent traveller, or anyone looking to conquer paper clutter on the go. Its single-cable operation, compact size, and impressive speed make it a standout product for ad-hoc scanning tasks. It empowers you to digitize and organize documents the moment you receive them, transforming dead time in a hotel room or airport into productive administrative work.
However, it is not without its compromises. The manual, single-sheet feed requires a degree of care and patience to avoid skewed scans, making it unsuitable for high-volume, unattended scanning. But for its purpose—scanning a few pages here and there, wherever you are—it is a powerful and reliable ally. If you’re tired of battling the paper tiger in your briefcase and value portability and simplicity above all else, the Brother DS-640 is an excellent investment that will streamline your workflow and lighten your load.
