POS touch screens make it capable for you to use a computer without a mouse or pad. You simply move your finger across the screen and the mouse pointer moves with it. A computer mouse needs regular cleaning to prevent it sticking and is easily damaged or stolen. POS touch screens and computers can easily be built into custom cases so that only the screen can be seen. This makes POS touch screens ideal for public places. You don't even need a keyboard with many systems, as a software keyboard can be displayed on screen when a user needs to type in information. Many POS touch screens also come with hand writing recognition software so that your on screen writing can be converted to text.
