EMV Chip Cards FAQs

What is EMV?

EMV stands for Europay MasterCard Visa and refers to debit and credit cards that contain an embedded microchip. EMV chip cards protect against fraud by providing strong transaction security features not possible with traditional magnetic-stripe cards. By storing card data on a chip, your account information can be changed actively with every use.

How does an EMV transaction work?

There is a fundamental difference between a magnetic-stripe and EMV chip transaction. With a magnetic-stripe card, the stripe stores data that is read by a terminal. The terminal initiates an online credit, debit, or prepaid transaction. Subsequently, the transaction is routed to/through networks and various payment processors for authorization. The physical card and stripe no longer play a role in the transaction once the initial data is read. An EMV chip card and an EMV-capable terminal interact in real time using more sophisticated cryptographic authentication technology. During an EMV transaction, the chip is capable of processing information and actually determines some of the rules for payment. The terminal helps enforce the rules set by the issuer.

How is the EMV chip card more secure?

The embedded microchip provides unique data specific to your card and to the transaction being processed. These security features make the chip card extremely difficult to counterfeit. If the card data and the one-time code are stolen, the information cannot be used to create counterfeit cards and commit fraud.

Can my EMV card become compromised? Is it possible fraudulent transactions can happen even though I have the EMV card?

Unfortunately, fraud can and will occur primarily through telephone or online ordering. All a fraudster needs is your card number, expiration date, and CVV number to make such purchases. You should always stay vigilant and observe all transactions to your account to help us stop this as soon as it happens.
