I've rode three Schindler PORTs with PORT 1 Series touchscreens before, and I have to say they are a little bit hard to touch without touching the screen/options a little bit harder. As for PORT 4 Series, yes, it is a lot easier to touch (only experienced this once before in Hong Kong a few years ago).
At least the new design have is using glass, which is just like Series 4. I am guessing if New Series 4 is also improved the ID Card system or not.
