The STU-430 is a small and robust, extremely durable signature pad. Its 4.5’’ monochrome screen is large enough to capture longer signatures as well as to accommodate soft buttons in addition to the signature area. The transflective LCD can easily be read in varying light conditions. A hardened glass surface protects the LCD screen and is highly resistant to scratches. The integrated pen compartment doubles as a USB cable lock to prevent accidental disconnection of the cable.
