Capacitive touchscreens are all glass and designed for use in ATMs and similar kiosk type applications. A small current of electricity runs across the screen with circuits located at the corners of the screen to measure the capacitance of a person touching the overlay. Touching the screen draws current to the finger and the software calculates a position of the touch.

Because the glass and bezel that mounts it to the monitor can be sealed, the touchcreen is both durable and resistant to water, dirt and dust. This makes it commonly used in harsher environments like gaming, vending retail displays, public kiosks and industrial applications with screen sizes form 8.4” up to 20”.
