Despite being a Brit, I own a small retailer in the the US. We have had to update our card terminals in order to comply with the new Chip rules coming in. Amazingly, there was only one machine that was authorized by our credit card company for use (a rather old-fashioned Verifone machine which did the rounds in the UK about 5 or 6 years ago at least), but it doesn't have contactless built in, and it can't deal with debit cards properly.

I am never ceased to be amazed at how backward the US banking system is in regards to payment systems - and the internet. And, it's nothing to do with fraud, as my US cards are compromised about once a year (and I don't use them very much at all), whereas my UK cards have never been compromised (touch wood), when I'm using them day in, day out.
