I used the same sources a couple years back to develop a MetroCard balance checker for iPhones. It used a cheap headphone jack magnetic stripe reader from China. Never got around to actually doing anything with it though.

Interesting! Do you happen to still have your source and/or research? I'd love to add it as a bullet on the post.
