Professional reviewers praise the DS-640 for its pocket-size design, versatile media support, and useful OCR suite, positioning it as a solid entry-level mobile scanner. However, they note its shortcomings in automation, especially the lack of duplex scanning, and point out that lighter competitors like the Epson DS-70 offer more advanced features such as automatic duplex and built-in battery.
Everyday users consistently commend the scanner's ease of use, portability, and scan quality, especially for receipts, ID cards, and long documents. Common complaints revolve around the absence of duplex scanning, occasional Windows 11 driver hiccups, and the need to stay tethered to a computer for power and data.

Professional reviewers praise its plug-and-play simplicity and rapid scanning, but criticize soft image output, limited dynamic range, and lack of touchscreen or advanced editing for serious archival work.
Everyday users love the speed, ease of use and the joy of seeing old slides again, while common complaints focus on soft image quality, the need for an SD card, and the tedious single-slide loading process.
“The OCR functionality is frequently praised for accurately converting scanned documents into editable text.”

“It's tedious, but worth it to see Mom again.”

“Not pro quality, but perfect for speed and convenience.”
