Privacy for Elo EloPOS Z30 for Android is a 2-way privacy protector that helps protect sensitive information from prying eyes by narrowing the viewing angle so that the screen is only visible to individuals directly in front of the screen. This is achieved via the embedded micro-louver technology that blacks out the screen at an angle of 30 degrees either side of the lit display without blurring or image distortion. Privacy adheres firmly to the screen with its advanced silicone based adhesive backing offering a smooth glossy surface.
