Wacom STU-430

Ideal for any signing environment, the Wacom STU-430 signature pad is a versatile, full-featured, monochrome signature pad with a new thin design and a low-profile surface. 

The 4.5’’ LCD screen is large enough to capture longer signatures, as well as to accommodate soft buttons in addition to the signature area.

Moreover, the screen is easily readable in varying light conditions. State-of-the-art encryption and a unique hardware ID ensure a secure signing experience.

  • Practical electronic signature capture via the 4.5-inch monochrome, reflective LCD display that easily accommodates larger handwritten electronic signatures, as well as soft buttons
  • Biometrically accurate electronic signatures using the digital pen with 1024 levels of pressure sensitivity
  • Low maintenance effort and costs through the use of Wacom’s patented electro-magnetic
    resonance (EMR) technology and batteryfree digital pen
  • Outstanding durability via the scratch-resistant hardened cover glass, proven during testing to  capture 500,000 electronic signatures with no surface wear
  • Secure transactions enabled by stateof-the-art AES256 / RSA2048 encryption
  • Secure PC connections via the integrated digital pen holder/USB cable lock combination, providing a dedicated area to place the pen
    when not in use, and a USB lock to prevent accidental disconnection of the USB cable
  • Enhanced signature traceability through a UID (Unique hardware ID) for identifying the exact signature pad unit used for a
    particular signature
  • Enhanced device security with built-in Kensington® Security Slot
