EMV is the acronym for Europay, Mastercard and Visa-the three credit card companies responsible for pioneering a new credit card technology in the 1990s. Though they were the first innovators, since then, all major credit card companies have adopted the technology, which has been in widespread use in Europe and elsewhere in the world for several years. On Oct. 1, 2015, that same standard will come to the United States as credit card companies enact the "EMV liability shift."
