Because there isn't a secret required to use them? Chipped cards 'solve' physical card use fraud (assuming they actually do the crypto they can do - there was another article about it not always being enabled). If processing networks just allowed it to be easy to generate one-time codes to replace putting in CN, exp, and CVV, then online fraud would be solved too. We have the tools to solve the problem, card networks just haven't deployed them.
