Obviously you're right!
Moreover, after I wrote the question, I've found that lots of people have mentioned using chip cards at Walmart.
Some have also said that if you hit the green button without entering a PIN, it switches to asking for a signature.
Very interesting about the "card must be inserted", too! Looks like we're all in for some changes soon.
Oh. Question: were you allowed to choose your own PIN?
I think you can only change the PIN on Wells Fargo cards because WF's ATMs support PIN change. Being that I have USAA, there are no ATMs near me to be able to try to.
I can also go to Europe and change it at any ATM there because it has to change on the chip itself.
I've never heard it was possible to bypass the PIN, unless it is allowed in the CVM (up to the card not the terminal). PIN bypass was normal in the UK, when they were Chip and Signature and PIN was being introduced. Same with Australia, until they stopped allowing Sig recently as well.
It is also normal for a terminal with the chip reader enabled to force chip insertion if it detects the card has a chip (service code is in the magnetic stripe).
So far Walmart, Home Depot and select stores like Zumies I've been to has the chip readers Enabled. (And NFC TOO, so bring on ApplePay!)
EDIT: Chase bank ATMs have manual card readers but if you pull out your chip card the ATM will start beeping and say you must leave the chip card in the machine until after the screen where you enter your PIN.
And gas pumps at QuickTrip gas stations in Phoenix! I hope to see more gas stations soon but they will be the last as their deadline isn't until 2017, where has a regular store is Oct 2015
Times are changing indeed and they're changing fast.
I've attached a picture of what happens when you use a Chip and PIN card at a Chase ATM, and you insert and remove your card instead of insert and leave in.
