As of October, 2021 EMV is now the standard card technology in the United States for in-store payment systems. Europay, MasterCard, and Visa (EMV), refers to the fraud reducing chip technology that is built into today’s payment cards. EMV is a global standard for the operation of integrated chip cards and chip enabled POS systems, ATMs and fuel dispensers.
The new chip on credit cards means payment security for almost 13 billion cards in 2024, and even relatively small gas station operators can expect ‘tens of thousands of dollars’ in fraud losses monthly for each station if they are not in compliance.
If you have yet to begin your EMV upgrade, contact D&H United as soon as possible as we can assist c-store retailers upgrade their sites to support EMV payments across different Gilbarco and competitive fuel dispensing products. Let our experts help you plan your EMV upgrades so you can begin your transition to EMV compliance.
