What’s an EMV chip card?
An EMV chip-enabled credit or debit card is a card that contains a small embedded chip. Every time the card is used at a chip-enabled terminal, the embedded chip generates a unique transaction code. It provides an enhanced level of security as well as global acceptance.

I have not received a chip-enabled card yet. When will I receive my new card?
We will begin issuing chip-enabled cards by the end of 2016. You can continue to swipe your existing credit and debit cards as you do now.

Am I still protected by Visa’s Zero Liability policy?
Yes. If your card is lost or stolen, you are covered by Visa’s Zero Liability policy. This means you are protected against unauthorized use.
