magnetic strip physical feedback

Check this article at hackaday.com The original post was on a myspace-page, but I cant manage to link to the single article
They use the resistance in the magnetic strip on a credit card to input data. In this design they use a finger drawn along the black stripe and a stripe of conductive metal tape to produce midi-info for a computer. But could this aproach be usefull in robotmaking? Would it be practical to use for reading the position of a robot arm? any other uses?
I have access to quite a few of these cards from an old security system, so if anybody can think of a worthy experiment, I'll gladly donate a few.
