Edit: clarifying - what I meant was that the US EMV cards will be chip and sig, not chip and pin. Most US cards are obviously still mag stripe. I'm traveling to Europe later this year so I was looking into the CC issues, and as a US traveler not being able to get an EMV card with pin priority is annoying.
Edit 2: jvm, not sure what you meant to link to, but that link just goes to the Forbes splash advert.
On the plus side Google Wallet works at Walgreens. I have yet to see any other brick and mortar support it. Paying for stuff with your smartphone is such a no-brainer. Shame Apple won't play ball with Google (or even put NFC in its phones) and Verizon is doing its own thing with ISIS and not allowing Google Wallet to be installed on any phones on its network. There's a lot of wrong here and its not just limited to credit card number theft.
If we have a more diversified way to pay for things it could limit the damage when one method is cracked but the others aren't. Sure Targets credit cards got stolen, but imagine if we were allowed to use Google Wallet. We'd be immune to it.
The newer cards have a microprocessor inside them, with exposed contacts about 10mm from the left edge. With chip + pin transactions, the pin "unlocks" the payment authorization [2].

There was a period where it was a guessing game every time you paid for something whether it was magstripe or chip (some locations even had a chip-capable machine, but didn't have the service enabled with their payment processor, so you still used the magstripe...).
It's pretty consistent now.
