They encode the transaction with a single use number and the card
information cannot be duplicated the way a swipe card can be. See below:

1. Why are EMV cards more secure than traditional cards?

It's that small, metallic square you'll see on new cards. That's a
computer chip, and it's what sets apart the new generation of cards.

The magnetic stripes on traditional credit and debit cards store contain
unchanging data. Whoever accesses that data gains the sensitive card and
cardholder information necessary to make purchases. That makes
traditional cards prime targets for counterfeiters, who convert stolen
card data to cash.


"If someone copies a mag stripe, they can easily replicate that data
over and over again because it doesn't change," says Dave Witts,
president of U.S. payment systems for Creditcall, a payment gateway and
EMV software developer.

Unlike magnetic-stripe cards, every time an EMV card is used for
payment, the card chip creates a unique transaction code that cannot be
used again.

If a hacker stole the chip information from one specific point of sale,
typical card duplication would never work "because the stolen
transaction number created in that instance wouldn't be usable again and
the card would just get denied," Witts says.

EMV technology will not prevent data breaches from occurring, but it
will make it much harder for criminals to successfully profit from what
they steal.
