Chip Credit & Debit Cards

Security with Peace of Mind

Your safety and security is important to us, so we issue credit and debit cards embedded with secure microchip technology. Our cards feature an EMV chip (Europay, Mastercard, Visa) – the global standard in technology and card security.

For more information, please review the Frequently Asked Questions (FAQs) below.

IMPORTANT: Always insert (i.e. ‘dip’) your chip-enabled debit card at EMV chip-enabled terminals by inserting the card into the chip reader when making in-store purchases. If you try to swipe your chip-enabled debit card using the magnetic stripe at chip-enabled terminals, your card will be declined.

General EMV FAQs

What is a chip-enabled credit or debit card?

A chip-enabled credit or debit card features EMV technology, which is an embedded microchip that provides an extra layer of protection against fraud.

What is EMV?

EMV stands for Europay, Mastercard, Visa. The card will have a small metal square on the front of the card above the card number. The chip will be in the same area on all TDECU chip-enabled cards as shown below.

The cards will also contain the traditional magnetic stripe on the back of the card for use with merchants who do not accept chip-enabled cards.

How are chip-enabled cards more secure than magnetic stripe cards?

Magnetic stripes on traditional credit and debit cards store unchanging data. If that data is breached, it may expose the sensitive card and cardholder information necessary to make purchases. That makes traditional cards prime targets for counterfeiters.

When a chip-enabled card is used for payment, the chip and payment terminal work together to create a unique transaction code that cannot be used again. If someone were able to gain access and attempted to use the unique code for a subsequent purchase, the transaction would be denied.

Does chip-enabled card technology ensure against all fraud?

No. While this technology is the global standard for card security, thieves will continue to look for new ways to commit fraud. When a chip-enabled card is used for payment, the chip and payment terminal work together to create a unique transaction code that cannot be used again. If someone were able to gain access and attempted to use the unique code for a subsequent purchase, the transaction would be denied. EMV chip-enabled card technology, however, will not protect against fraudulent activity in instances of non-present card transactions, including purchases made over the phone and online.

As your credit union, TDECU will continue to employ the most sophisticated fraud prevention tools available to ensure the integrity of your account(s).

How will I know whether I need to swipe or insert my chip card when making an in-store purchase?

It depends on the type of terminal the merchant is using. If the merchant terminal accepts chip cards, you will see a slot in which you will insert your card and where it will remain during the transaction. If the terminal does not accept chip cards, you will swipe your card as you do today.

Is it true that chip card information can be stolen with an RFID scanner?

No. Information contained in the chip cannot be stolen with an RFID scanner. The chip creates a unique code each time it is used and must be in contact with the terminal to complete the transaction. This makes it much more difficult for criminals to duplicate and use your card to commit fraud.

Is a PIN required to complete a transaction with a chip-enabled debit card?

Yes, sometimes. This depends on the merchant, so it is important for the cardholder to know the PIN associated with their chip-enabled credit or debit card. Credit card PINs are required for cash advances at ATMs.

How will I know whether I need to swipe or insert my chip-enabled debit card when making an in-store purchase?

This depends on the merchant. If the merchant terminal accepts chip-enabled cards, you will insert (i.e. ‘dip’) your chip-enabled debit card into the card slot where it will remain during the transaction. If you try to swipe your chip-enabled debit card using the magnetic stripe at chip-enabled terminals, your card will be denied.

How do I use my TDECU chip-enabled debit card for online purchases?

Your chip-enabled debit card will work in exactly the same way as your previous debit card for online purchases.

How do I pay for a purchase at a chip terminal?

Follow these easy steps to pay at a chip-enabled terminal:
