EMV 是国际金融业界对于智能支付卡与可使用芯片卡的POS终端机以ATM机等所制定的标准。EMV智能卡（也称为IC卡）的信息储存在集成电路中而非过去的磁条里，但大部分EMV卡背也有可以向下兼容的磁条。芯片可以和插入式读卡器交换数据，非接触式智能卡还可以使用射频识别（RFID）技术在一定范围内交换数据。符合EMV标准的支付卡叫做芯片卡。

EMV三个字母分别代表Europay、MasterCard与Visa，是制定该标准最初的三家公司。目前标准由 EMVCo 机构管理，EMVCo最初由EMV三大组织于1999年2月共同成立，目前由Visa、Mastercard、JCB、美国运通、中国银联和Discover共同负责。主要任务系发展制定与主管维护EMV支付芯片卡的规格、标准与认证，监督并确保该标准于全球的安全互通性与其付款环境的可用性。

EMV is a technical standard for smart payment cards and for payment terminals and automated teller machines that can accept them. EMV (Europay, MasterCard and Visa) cards are smart cards (also called chip cards or IC cards) which store their data on integrated circuits rather than magnetic stripes, although many EMV cards also have stripes for backward compatibility. They can be contact cards that must be physically inserted (or "dipped") into a reader, or contactless cards that can be read over a short distance using radio-frequency identification (RFID) technology. Payment cards that comply with the EMV standard are often called chip-and-PIN or chip-and-signature cards, depending on the exact authentication methods required to use them.
