But this gets filed as "infrastructure is hard". A related example: If you get a chance, try the IC card system used by the train and transit systems in Japan; they're delightful.[1] At peak rush-hour, commuters are darn near running through the (many) pay stations tapping through without breaking stride -- including display of remaining balance!
Yet, the relatively recent transit tap card system where I live is laughingly slow. At a much more modest walking pace, it's easy to pull away from the reader before it's confirmed the transaction. Seconds per commuter, for system that's considerably newer than the IC card system.
We also have contactless payment on most of our credit cards (as in built into the card, not Android/Apple Pay) and support for it on ~90% of terminals as well though so it's not much used anymore.
Prompt #1: Credit/Debit?
Prompt #2: PIN
Prompt #3: Would you like cash back
Prompt #4: The total is $xx.xx, ok?
This is time consuming, particularly for people who aren't as comfortable with electronics and pressing buttons. And on top of that, many times the terminals themselves are slow.
Pay-at-the pumps are even worse
Prompt #5: Are you a fuel perks member?
Prompt #6: Receipt yes/no?
Prompt #7: Would you like a car wash?
and they're often even slower, the buttons are often hard to press, or don't register a beep and have a delay before the machine responds, so you wind up pressing the same one twice. And most lack a 'backspace', the screens suck, man don't get me started....lol
Everyone else, yeah, pretty slow.
I am surprised that apparently only 1 vendor has figured out how to make a good chip reader, and I am sad that apparently other retailers don't care enough to buy from that one vendor.
I personally used my credit card at one of the affected stores, and I do not plan on calling in to have my card number changed. I'll just keep a close eye on my statements (that, and I have alerts sent to my phone via SMS for any charge over $0.01, so I'd know pretty quickly)
There is no way too know if you are actually doing and EMV transaction.
The EMV spec has nothing at all to do with security. PCI controls security. I can read the card data via the chip and it's all in the clear. EMV is about process integrity, and the integrity testing is ridiculous. Chip cards are harder to forge, but that's about it. The new rules about liability puts the liability for processing a forged card on the merchant, if the transaction isn't done with EMV.
What other customer information could have been affected? Kudos on the masterful PR spin — I guess by now Chipotle has had a lot of practice at this...
