The TaoTronics Document Scanner is extremely portable and very affordable. It's handheld, but produces very good quality files.
Pro Great for scanning difficult surfaces, such as books
Unlike most scanners, this TaoTronics can scan almost any surface, since it's handheld. For example it's easy to scan books, which would not fit into a sheet-fed or flatbed scanner, where the paper has to go through or into the scanner.
Con Each scan creates a new PDF
There is no option to scan several pages into one PDF file. This can be a headache when scanning documents longer than one page, since you will end up with a lot of PDF files. Luckily, there is free software available online that lets you merge several PDF files into one. Of course, this takes some extra effort.
Con Poor character recognition software
Optical Character Recognition (OCR) software transforms a scanned picture into editable text. The OCR that this scanner comes with is not capable of consistently reading characters accurately. Also, this software is not Mac or Windows 10 compatible — it was made for older Windows operating systems. Of course, you can always get other OCR software that is compatible with your system.
