TWAIN, an acronym for Technology Without An Interesting Name is a standard for the application program interface (API) between input devices like book scanners and applications which control the image input device such as capture software. Using a TWAIN-compliant application like open office and TWAIN-compliant scanner with TWAIN-compliant drivers allows users to operate scanners in a similar way.

Book2net scanners are fitted with optional TWAIN drivers giving users the possibility to log in with TWAIN-compatible applications like Adobe, initiate scanning via Adobe scan command, then book2net capture software will start scanning with specified settings. TWAIN functions with TIFF (Tagged Image File Formats) file and is appropriate for doing optical character recognition (OCR) to create text output.
