This is interesting. I would totally believe that with the information you can intercept passing between the chip and the reader, you could in some cases construct magnetic stripe data that would be recognized as valid. It kinda seems like the magnetic stripe system should be completely separate from the chip system. Make it so that the card ID (or whatever) reported by the chip can never be used for swipe transactions, and vice-versa. Combining them just seems to cross-product-ify the attack surface, which is dumb.
