Questions tagged [emv]

EMV stands for Europay, MasterCard and VISA, a global standard for inter-operation of integrated circuit cards (ICC or "chip cards") and ICC capable point of sale (POS) terminals and automated teller machines (ATMs), for authenticating credit and debit card transactions. It's the application structure inside your smart card that handles requests for protected data and communicates with the issuing bank to confirm the authenticity of the card user.
