SHOPSTAFF Rating Score
The Brother DS-640 is a portable scanner suitable for basic document digitization. Its compact design and USB power make it convenient for travel, but its scanning speed and lack of advanced features limit its use for high-volume tasks. The software is adequate for simple tasks, but users may prefer third-party options. Expect a lifespan of a few years with moderate use.
