Can I use a normal pen to touch the screen and does MicroTouch sell a specific “stylus”?
A normal ball point pen can be used to touch a resistive touchscreen. The repeated use of a sharp pointer such as a pen in a small area of a standard resistive touchscreen will likely cause premature visual wear of the touch sensor without affecting its actual touch performance. Occasional random use of a stylus will not adversely affect the screen. MicroTouch does not sell styli for use with resistive sensors. Cross and Pilot, both prominent manufacturers of pens, each have lines of styli for use with resistive devices.
