What’s TWAIN

TWAIN is a standard software protocol defined by TWAIN Working Group. It is an applications programming interface (API) that regulates communication between software applications and imaging devices, such as scanner, digital camera and capture card.

With several popular scanner manufacturers being initiators of the TWAIN Working Group, most, if not all, scanners come with a TWAIN driver and are TWAIN compatible.

If you have an interest to know the difference between TWAIN and other scanning protocols such as WIA, ISIS, SANE, you can also check Document Scanning: TWAIN, WIA, ISIS or SANE?
