How Each Alternative Compares
Epson WorkForce Mobile Document Scanner
The Epson ES-50 is significantly lighter than the Brother DS-640, weighing just 9.44 ounces compared to the Brother’s 1.03 pounds. It is also narrower, measuring 1.8 inches in width versus 2.2 inches. This makes it easier to slip into small bags or pockets. However, it lacks the Brother’s software suite for OCR and advanced image adjustment. You get basic USB connectivity and single-sided scanning only. If you need extreme portability for occasional receipts or single pages, this is a solid choice. It gives up speed and features for a smaller footprint.
Brother Compact Mobile Duplex Scanner
The Brother DS-740D adds duplex scanning capability, which the DS-640 lacks. It scans both sides of a document in a single pass. This doubles your effective throughput for two-sided papers. The DS-740D is slightly heavier at 1.43 pounds and wider at 2.5 inches. It retains the same compact form factor and USB bus power. If you frequently scan double-sided documents like contracts or forms, this is the better pick. It sacrifices minimal portability for a major workflow improvement. You keep the Brother brand reliability and mobile design.
Epson Portable Single-Sheet Scanner
The Epson DS-70 is nearly identical in dimensions to the Epson ES-50, measuring 1.8 by 10.7 inches and weighing 9.44 ounces. It is much smaller and lighter than the Brother DS-640. It offers single-sided scanning via USB. It does not include the advanced OCR or color adjustment features found in the Brother’s software suite. It is designed for travelers who need a tiny, lightweight device for quick scans. If you prioritize size over speed and software, this is a strong alternative. It gives up the Brother’s 16 ppm speed for a more pocket-friendly profile.
Canon imageFORMULA R10 Portable Duplex Scanner
The Canon imageFORMULA R10 provides duplex scanning, unlike the single-sided Brother DS-640. It is slightly longer at 11.2 inches but narrower at 3.75 inches wide. It weighs 2.2 pounds, which is heavier than the Brother. It uses USB connectivity only. The Canon is built for light mobile use rather than heavy office workloads. If you need to scan both sides of documents while traveling, this is a practical option. It offers duplex capability in a portable package. You trade the Brother’s lighter weight and lower price point for two-sided scanning ability.
HP Portable USB Document Scanner
The HP HPPS100 is extremely lightweight at just 3 ounces, making it the lightest option here. It is also very slim, measuring 2 inches wide and 1.4 inches high. It offers single-sided scanning via USB. It lacks the Brother’s software suite for OCR and cloud scanning. It is ideal for travelers who need a bare-bones scanner for occasional use. If you want minimal weight and simple operation, this is a good choice. It gives up speed, duplex capability, and advanced features for a tiny, portable form factor that fits easily in a pocket.
HP Compact Duplex Mobile Document Scanner
The HP HPPS200 offers duplex scanning, which the Brother DS-640 does not. It is larger and heavier, weighing 3.14 pounds and measuring 4.1 inches long. It provides professional speed and high resolution. It connects via USB. It is designed for mobile professionals who need duplex capability without carrying a desktop unit. If you need to scan both sides of documents on the go, this is a robust option. It sacrifices the extreme portability of the DS-640 for faster duplex performance and higher build quality.
