Extended information:

The three letters of EMV stand for Europay, MasterCard and Visa respectively, and are the first three companies to formulate the standard. The current standard is managed by the EMVCo organization. EMVCo was originally jointly established by the three major EMV organizations in February 1999. It is currently jointly responsible for Visa Mastercard, JCB, American Express, China UnionPay and Discover.

EMV is a standard established by the international financial industry for smart payment cards, POS terminals and automated teller machines (ATMs) that can use chip cards. The information of EMV smart cards (also known as IC cards) is stored in integrated circuits instead of the magnetic stripes of the past, but most EMV cards also have magnetic stripes on the back that are backward compatible.

EMV standards are jointly initiated and formulated by the three major international bank card organizations - Europay (European Card, acquired by MasterCard), MasterCard (MasterCard) and Visa (Visa) *** The technical standard for card transfer from magnetic stripe cards to smart IC cards is a financial payment standard based on IC cards and has become a recognized global unified standard.

The purpose of the EMV standard is to establish a unified standard for card and terminal interfaces in the financial IC card payment system, so that all cards and terminals can be interoperable under this system, and the adoption of this technology will be greatly improved. The security of bank card payments reduces fraud.
