Rated 5 out of 5 by from Best investment for my business Compact, efficient and gets the job done. Receipts are a constant in my business and the DS-940DW scans them with no fuss. Either USB or wireless, the performance is great.

Rated 1 out of 5 by from DS-940DW disappoints I bought the DS-940DW as a natural progression from the 620 via the 720 and 920, which all use Button manager software. The DS-940DW does not, the software that comes with it is rubbish. I want to be able to click one button and have my PDF appear in the folder of my choice not to have to spend ages setting it up each time. I have chucked the DS-940DW at the back of the cupboard and bought another 720. Very disappointed.

Rated 5 out of 5 by from Brilliant - why did I wait so long? Fantastic scanner. I already have a scanner attached to a printer but I wanted to scan a box of old photos and needed something less cumbersome. This scanner is portable. So I have scanned all my photos directly to OneDrive whilst watching the TV. I now use the scanner to scan everything - documents, receipts, you name it! Why keep paper when you can scan. I love it!

Rated 5 out of 5 by from Super pratique Je possédais la version antérieure (avec un display difficilement lisible). Les Leds sont bien plus pratique et la sortie du papier a été améliorée. Un des rares à avoir encore une carte mémoire. J'en suis très satisfait.

Rated 5 out of 5 by from Time Saving Powerhouse - scanner [This review was collected as part of a promotion.] I received this product for free from Brother in exchange for my honest opinion/review of the product. Last year I started my new small business and officially registered my LLC. Budgeting and receipts have never been my strong suit. I just would throw them in a folder and deal with them at tax time. Or, sometimes I would go the extra step of using a free scanning app on my cell phone, snap a pic with my phone, save it, then have to email it to myself to open on my PC, and then save to my PC. It was so many steps. Then this app that I had been using for years was found to have a glitch in which your files could be hacked. So I deleted the app and had to go back to my paper file folder. Enter Brother DSmobile DS-940sw! I had no idea that a handy little scanner existed! I love that it is compact and can sit next to my computer in the little space I have on my desk. It is 12.5 inches long and about 2 inches deep. It really is about the size of a spaghetti box! It has a wireless option, but setting it up wired was enough for me since it sits connect to my laptop. I have not yet used it OUT of my home office, but I can see taking this with me to meetings to have clients sign forms on the spot and give them the original copies back. It scans documents of all sizes, including receipts. I haven`t tried scanning credit cards and my drivers license - but plan to so that I have everything saved in my important documents file on my computer. I love how fast the documents and receipts go through. One of the features of scanning on a machine with a lid you have to lift to scan the next page, is the time and annoyance of it. Not with this handy little tool. Page after page automatically, even double-sided. I do wish this had a carrying case so that I it doesn`t get damaged if I decide to travel with it. It fits it my laptop cover case (it`s just a little big), so that works for now.I`ve only had this unit for about 10 days so I`m still learning about all the ways I could use this, like scanning my credit cards and drivers license so that I have them on file. The search feature for my scanned receipts is going to be a lifesaver when I need to find that receipts for tax season and even for my personal receipts. When I have a return for a store, I have to search through hundreds of paper receipts now. I`m going to scan all my 2019 receipts just for fun actually my kids think it`s fun using this Brother DS-940DW too! They`ll be helping me. I needed my husband`s help to get the drivers for my scanner set up on my computer and get it all set up. I tried on my own to know avail. But I`m not good with that aspect of computers. I wish that the Quick Set-Up Guide would have this statement bigger (perhaps REALLY big so people could see it!) so that I knew I had to retrieve it online. "The latest manuals are available at It is literally in such small type!I`m so excited use this little tool and it is going to help me get my receipts organized for taxes next year!
