DO NOT BUY FOR RECEIPTS ON MAC
I bought DS-640 specifically for its ability to scan receipts up to 72" and compatibility with macos. It was a mistake. This scanner is what's known as "abandonware". Brother's entire software support for it consists of a driver, firmware update and a 2019 version of their iPrint&Scan software. Driver is not an issue, you can just plug it in and use macos' own scanner soft in System Preferences. But as you know macos built in scanner soft only goes up to A4. To scan receipts longer than A4 you need Brother's iPrint&Scan software to work. And that's where things fall apart. It's October 2022 and two years on Brother still haven't released iPrint&Scan that works with Apple Silicon USB port structure. If you're on M1, M1 Pro, M1 Ultra or M2 you're in 99% cases out of luck as these are USB4/Thunderbolt ports. So although firmware update dmg and iPrint&Scan will open on Apple Silicon machines, it won't detect the scanner connected to USB to update or scan anything. You're stuck with macos builtin scanner support and maximum A4 size because Brother just keeps releasing scanners and printers and then abandon any software updates within months...

Great Document Scanner! - not a texture scanning wand.
Super easy connect and start scanning. Great form factor easy to bring with you. Doesn't get jammed easily, I even use this to make janky images by pulling the paper while it's being scanned - doesn't bother the machine too much. Only says jammed when the paper stops, so long as it's flowing through it doesn't stop. If there is a jam it is easy to clear. This is not a pocket wand that you can scan any surface. It is strictly a portable document scanner and a good one at that. the brother app is easy and intuitive to use; you can make full multiple page pdfs in minutes. I can't really attest to the durability as I haven't really put it through the wringer in this department, but it feels like I could drop it a few times and not hurt anything.

Práctica
Su relación calidad - precio es muy buena. Por lo que se paga no se puede exigir más. Es un buen escaner, lo hace a color y con buena resolución. Es un poco incómodo tener que escanear hoja por hoja y no poder tener un alimentador que permita escanear varias hojas al mismo tiempo, pero al final cumple con su función. Es muy ligero, no pesa mucho. Muy practico de transportar y muy fácil de usar. Para trabajos sencillos, muy bueno

Space saving.
Good replacement for my flat bed scanner. Easy to setup (just connect cable) and takes very little space on my desktop. Document feeding takes a bit of practice and can be difficult if the document is not flat.

Custo X Benefício X Praticidade
Isso sim é praticidade e eficiência. Scanner com preço justo, leve, eficiente, rápido e prático. Vi antes da comprar em alguns comentários que a leitura era lenta. Sinceramente, quando chegou, umas das coisas que mais me surpreendeu foi a velocidade. Convenhamos que não vamos esperar uma velocidade de produto que foi feito para escanear mais de mil folhas dia. Recomendo a compra do produto! Agora é esperar 1 ano para nova avaliação.
