EMV system is what you are referring to?
Yes. Here is an explanation. In particular, see items 4 and 8.
http://www.creditcards.com/credit-card-news/emv-faq-chip-cards-answers-1264.phpI live in the US and have traditional cards. My sister lives in the UK with EMV cards. When I visit the UK, there are many terminals that will not accept my US based cards. Every time she uses her card, she is required to enter her pin.
