Thanks for the info, Ray. I suspect 'gunk' will be a major concern with these new smartcards, since the technology will be like what is used in a hard drive. The heads will probably be rotated over the card, and very close to the card surface. I seem to recall the keeper layer allows increased flying heights, and they may decide to sacrifice data capacity for greater head to media spacing to reduce the effect of 'gunk' on the card surface. In the present technology used in swiping cards, is the head spaced a set distance from the card? Or does it come in contact with the magnetic stripe? I recall pictures of what smoke and dust particles look like under magnification on a disk surface. The heads are so close to the media, it would be like crashing your car into a high-rise building.
