2. You do not need to open up the computer case. There are two types of controller boxes: USB and ProE (com port). The USB controller is used for Win 98, ME, 2000, XP, Vista, 7, and Linux or Mac OS 8-10. The USB controller can be plugged into the computer’s USB port without turning the power off. The ProE controller is used for Win 95, 98, NT4.0, ME, 2000, XP, Vista, 7, and Linux. It needs to be plugged into a free com port. No other power source is needed - you can use it in any country.

Magic Touch is made by resistive technology and will soon be available with
capacitive technology. Resistive technology is the most popular because it
provides the highest touch resolution, fastest touch response and can be activated by
anything. Capacitive technology requires skin contact to operate. Surface Acoustic Wave
(SAW) technology is sensitive to moisture and dust.
Theoretically, it is true when the applications are
primarily used for drawing or writing by stylus. There is no
obvious difference for common touch screen applications, such as
education, gaming, point of sales, kiosks, etc. Although
KEYTEC'S traditional Magic Touch is 4-wire design, 5-wire models
are also available for many standard sizes. Please
contact us for more information.
12. Magic Touch has been consistently tested to 3 million touches without showing any functional failure. Our testing lab did not run the testing beyond 3 million touches, because we believe this kind of reliability is suitable for almost any application. In fact, we have customers reported that their Magic Touch screens have been working for more than 10 years.
There is no standard testing method has been established in the touch screen industry, thus it is not possible to make a fair comparison. We choose to publish only the minimum life testing data, instead of making meaningless exaggeration for marketing purpose.
