The Pro Touch 2 is a lightweight, through-glass Touch-Screen Film technology that applies to windows, glass surfaces, acrylic, and other non-metallic materials. With no external wires or devices, all Touch-Screen Film components are situated safely behind the viewing surface, and interactivity works even with a gloved hand. The Pro Touch 2 is not affected by external light conditions. Pro Touch 2 interactive touch foils are designed to accommodate one or two simultaneous touches at the same time. What this means is that you can interact with the foil just as you would your iPad, iPhone, or iPod Touch with gestures like pinching, dragging, zooming, and others. If you need to have the ability to zoom in on pictures or a map for instance, then Pro Touch 2 foil technology may be right for you.
