"Chip & signature" cards are surprisingly well-deployed already, at least on the card side. I've received several new cards in the last 6-12 months with a chip, but apparently no PIN. Walmart's payment terminal made me use the chip when I tried swiping (AmEx). I don't know if that behavior is selective based on transaction value or something, but that particular card may already be incompatible with Coin.
