The SAM4S SPT-4846 vibrant precise 15 projective capacitive multi-touch display is extremely durable in most environments including withstanding water contact, dust and grease. The SAM4s Capacitive touch panels will activate with either a bare finger or a capacitive stylus preventing users from using pens, credit cards or sharp objects which potentially would reduce the life expectancy of resistive touch panels. In addition the screen has a more vivid and crisp colour enhancing the quality of the POS user interface.
