Wacom STU-430 4.5-inch Signature Pad

Ideal for any electronic signing environment, the STU430 is a versatile, full-featured, monochrome signature pad with a new thin design and a low-profile surface. The 4.5-inch LCD screen is large enough to capture longer handwritten electronic signatures, and accommodates soft buttons in addition to the signature area. The screen is easily readable in varying light conditions. State-ofthe-art encryption and a unique hardware ID ensure a secure signing experience.
