EMV Liability Shift

The EMV liability shift refers to a policy change implemented by major card networks, including Visa, MasterCard, American Express, and Discover, aimed at encouraging merchants to adopt EMV (Europay, MasterCard, and Visa) chip technology in their payment terminals. EMV technology significantly enhances security by using a chip embedded in the payment card to authenticate card transactions, which is more secure against fraud than the traditional magnetic stripe.

Prior to the liability shift, credit card issuers were generally responsible for covering the costs of fraud from counterfeit card transactions. However, with the introduction of the EMV liability shift, this responsibility now falls on the party—either the merchant or the issuing bank—that has not implemented the EMV chip technology. Specifically, if a fraudulent transaction occurs using a card equipped with an EMV chip at a terminal that does not support EMV chip transactions (i.e., the terminal only reads the magnetic stripe), the merchant is held liable for the fraudulent charges.

This policy shift has effectively motivated merchants to upgrade their systems to accept EMV chip transactions, thereby reducing fraud risks and aligning with global standards in payment security. It has led to a widespread upgrade of payment infrastructure, significantly lowering rates of credit card fraud in card-present transactions.
