How to Scan Documents Online and Upload as Images
Dynamic Web TWAIN SDK enables fast and large-volume scanning.
All three transfer modes are supported:
Native Transfer Mode is used by default. In this mode, images are managed by the service.
File Transfer Mode enables images to be transferred directly to the hard disk. If the scanner compresses the scanned images fast enough and the hard disk has a high write speed, then the pages can be scanned at the top speed of the scanner.
Memory Transfer Mode is also supported and may help in cases where the client machines have limited physical memory.
