Surface Acoustic Wave Touchscreens
The Surface Acoustic Wave (SAW) technology is one of the most advanced touch screen types.
Because the panel is all glass, there are no layers that can be worn, giving this technology the highest durability factor and also the highest clarity. Compared to resistive and capacitive technologies, it provides superior image clarity, resolution, and higher light transmission.
This technology is recommended for ATMs, Amusement Parks, Banking and Financial Applications, public information kiosks, computer based training, or other high traffic indoor environments.
