Review Summary

This is the summary of consumer reviews for Brother DS-640 Compact Mobile Document Scanner. The BoolPool rating for this product is Very Good, with 4.40 stars, and the price range is $65 - $110.

The Brother DS-640 Compact Mobile Document Scanner is an ultra compact scanner device that only weighs 1.5 pounds, making it easy to bring on the go, stick in a bag, or keep in a storage drawer when not in use. This scanner is perfect for small documents, and hooks directly up to a computer or device thanks to the included USB cable. This scanner prints in both color and black and white, so it works for virtually any simple office project. The scanner works for documents longer than the standard page size, including IDs, credit cards, and longer receipts. The scanner also comes with a free software to import scanned documents.

Customers say this product works well because it can do simple tasks easily. They say they love how small it is, which makes it a good purchase for a small office space or for someone who does not need to scan very often.

Some say they really struggled with this product. They say it sensed a jam quite often, especially with receipts longer than 12 inches. Others say the software did not work well at all.

I thought I was buying a scanner that I could use with the "buttons program" that came with my 620 but Brother came out with another program that's more user friendly for beginners.
