This is a portable document scanner (13 megapixels). I bought it to try it out, and I've used it a few times, so it's almost like new. ● This portable document scanner is ultra-compact but can scan up to A3 size. ● It's foldable, making it convenient for carrying and storage. ● The joints are freely movable, so you can easily switch between using it as a document camera to photograph documents and as a web camera to show your face, making it convenient for web conferences and meetings. ● The camera position can be freely adjusted, supporting a wide range of sizes from business cards to a maximum of A3 size. ● It supports both Windows and Mac, and software and manuals are available for each OS. ● By installing the dedicated software "VIISAN," you can operate and adjust the scanner. It supports continuous shooting, video recording, barcode recognition, OCR, and more. ● It comes with non-slip pads to prevent slippage and a cable clip for neat wiring. ● It includes a scanning mat, a storage pouch, and a conversion adapter for the Type-C port.
