Normally we like to blame the victim, but in this case we need to thank them. From the WSJ, the swap to Chip and PIN will happen by October 2015. Here is the key point:

Part of the October 2015 deadline in our roadmap is what’s known as the ‘liability shift.’ Whenever card fraud happens, we need to determine who is liable for the costs. When the liability shift happens, what will change is that if there is an incidence of card fraud, whichever party has the lesser technology will bear the liability.

So if a merchant is still using the old system, they can still run a transaction with a swipe and a signature. But they will be liable for any fraudulent transactions if the customer has a chip card. And the same goes the other way – if the merchant has a new terminal, but the bank hasn’t issued a chip and PIN card to the customer, the bank would be liable.

None of this affects online transactions, though.
