High-Performance and robust: Wacom STU-500.

The STU-500 is a real all-round talent: With its 512 real pressure levels, paper-like surface, rapid real-time visualization and brilliant TFT-LCD display, the STU-500 provides a natural writing feeling. With a VGA resolution of 640 x 480 pixels, it can display additional content such as transaction amounts. The display also contains a sensor under tempered glass – ideal for daily use at public counters or check-out systems.
The 5-inch monochrome screen of the STU-500 is wide enough even for long e-signatures. Its reflective TFT technology means there is no need for backlighting, which makes for considerably lower energy consumption and a longer lifetime.
Thanks to these features, the STU-500 is the ideal signature pad for day-to-day use at public counters, allowing the capturing of millions of digital signatures.
