The EMV specification defines technical requirements for bank cards with embedded microchips and for the accompanying point-of-sale (POS) infrastructure. With few exceptions (primarily in the United States), financial institutions worldwide issue EMV bank cards to businesses and consumers.
According to EMVCo, approximately 1 billion EMV cards have been issued globally and 15.4 million POS terminals accept EMV cards. The primary purposes of including a chip in a bank card are to store cardholder data securely, protect data stored on the chip against unauthorized modification, and reduce the number of fraudulent transactions resulting from counterfeit, lost, and stolen cards.
