My CC went chip a few weeks ago.
Half the time I still have to swipe it. Half the time I seemingly don't insert it all the way. I've never been asked for the PIN yet - apparently here the store is responsible for bad charges if a PIN is used, but the CC company is responsible if it's still swiped or just inserted. Or something.
Things are very slow to change here....
Cheers, Scott. (Who expects he'll be using his (next) phone for payments in 2017 or so.)

You have no idea the number of combinations possible
Does this card link to one or multiple accounts?
Is any of those accounts debit? Global debit? (There's a difference.)
What authorization methods does the card's issuing bank support? For each account?
What authorization methods does the merchant's bank support?
Do those methods depend on the value of the transaction? Before or after tax? Before or after currency conversion?
Speaking of currency conversion ... no, actually let's not.
And if the chip read fails - rare, yes, but to certify the platform you have to develop, test and demonstrate the fallback mode - what are the answers to all those questions when swiping? Are the answers different when in fallback mode than when using an older card reader that doesn't support chip yet?
The implementation guides for this stuff run 400+ pages, and each party has their own guide: the merchant's bank, the payment processor, the card reader manufacturer. And the guides are updated twice a year, with changelogs each of the last few updates running 4-5 pages single spaced.
It would have been faster, cheaper and more secure to simplify the options, but no one wanted to give up their particular way of doing things, so we implemented all of them.

" if the chip read fails - rare," the readers however fail a lot
so you swipe the card but the CC company knows that retailer uses a chip so fails to authorize the purchase. Actually I am starting to carry around a checkbook lately.
always look out for number one and don't step in number two

And your check has all the information needed to access your checking account with a forgery.

Unpossible!
And it's not that the bank knows the retailer uses chip. It's that the device knows the card has a chip.
If the magstripe indicates that the card has a chip, the reader must have already implemented the three tries before fallback is authorized, and logged each failure. The reader either sends a message saying, "Authorize this chip" or "Authorize this magstripe in fallback mode".
IOW if your system is set up right, and the device has a hardware failure that causes it to not just fail to read the chip but fail to register that it's even been inserted, it should never allow you to even attempt a swipe.
Defense-in-depth suggests that the bank should also enforce this, but what exactly would you send in the case of a failed read?
Gah! Stop making me think about this!

Luddite! :)
Think of the kickback you could have gotten. At least 1%.

Technically, it is chip + signature
Fell off my chair when I first realized that. This was the banks' choice. They're of the opinion that GenPop would be unable to comprehend an immediate transition to chip + PIN.
But the stores did stop asking for signatures, so if you find a PIN card, you can go shopping...
