New " 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.

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

New so do most of my credit cards, happened twice last year.

New 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!
