WM near Pearl City (Oahu) Sunday accepted my AMEX. In fact the mag strip option was disabled which threw me off.

Also saw one at the downtown Costco. Tried several insertions, but no luck.

The only places EMV will work in the US are at Wal-Mart and at some shops using systems provided by either First Data or Chase Paymentech. Most merchants have the terminals, but have EMV disabled. Costco surprises me though, they're one of the few that I thought didn't have the terminals anywhere.

The magstripe reader wasn't disabled at your Wal-Mart, BTW, if EMV is enabled you can't swipe an EMV card. If you could, EMV would be utterly pointless.

Added it to the map over at http://emvacceptedhere.com/ (I think. There was only one in Pearl City according to Google, at least.)

There doesn't seem to be much on the west coast right now. I wonder if any of the Walmarts in places like LA have EMV readers enabled (Popular tourist area).

There's a couple of EMV enabled places on the West Coast mentioned in this thread. I need to add them to the map too.

BTW, anyone can add new entries to the map as well.

Okay, the places mentioned in this thread should all be on the map. Feel free to report an entry if you see a problem.

Walmart in Helena, MT is now enabled as well. I added it to your map :)

You went all the way to Helena to try it out? ;)

No I bought some stuff at Walmart while in Helena. LOL

P.S. I was back at Walmart in Helena today, so I can confirm this wasn't a fluke - it's much, much faster than in Missoula.

Missoula it's honestly pretty darn slow. Not unbearable, but... like dial-up card processing is, ya know? In Helena it's lightning fast - the fastest I've seen EMV run, just a few seconds.

Wonder why they're different?

Another liquor store by my house looked like they had a terminal with EMV support (and a contactless reader), but the clerk took my card and swiped it himself with another terminal.

Also, one of my local Costco stores didn't have EMV. Honestly, though, I expect Costco to be one of the last holdouts. They pretty much know where you live by virtue of needing to be a member, so why commit credit card fraud there?

Exactly, Costco is VERY anti-EMV, though their extremely vocal opposition died down after Target. Costco, like Target, is also one of the chains that doesn't already have the hardware everywhere.

You're right in that no one would USE stolen data at Costco, but I think Target made places like Costco wake up and realise that being liable for the use of stolen cards is only half the battle, not, yourself, being the SOURCE of counterfeit cards matters too.

In my experience, very few people use credit cards at Costco, and many of them are using the Costco-branded Amex. They don't take Visa or Mastercard, which are by far the most common, so the majority of shoppers use cash or debit anyway.

Debit is going EMV too...

Yes, but debit already uses PIN so there's less pressure to switch to chip.
