EMV bank card shipments, including dual-interface cards that support contactless payments, are increasing globally, but the future of the contactless infrastructure in the U.S. remains to be seen.

Standards group EMVCo, owned by Visa, MasterCard Worldwide, American Express, China UnionPay, JCB and Discover Financial Services, is still excluding the U.S. from its data on card and terminal rollouts. EMV deployments in the U.S. aren’t expected to gather steam until later this year.

As of the fourth quarter of 2013, the organization reported 36.9 million EMV point-of-sale terminals active worldwide. There were just under 2.4 billion EMV cards on issue globally, according to the group, nearly all in Europe, Asia-Pacific and the Middle East and Africa. EMVCo did not specify how many of those were contactless POS terminals or dual-interface cards
