The Brother DS-920W is a mobile scanner that can scan up to 5 duplex-printed A4 pages per minute, whether you're at the office or somewhere else. You can scan and digitize all your paperwork, photos, and business cards with this scanner. What if you don't have a PC with you? You can scan your documents to the included 4GB SD card with the push of a button, so you can save them without requiring a PC or laptop. Thanks to the rechargeable battery, you don't have to go looking for a socket every time you want to use the DS-920W.
