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.
As the U.S. payment industry transitions to EMV technology, there’s a lot to adjust to, starting with what to call the new cards. They might be called any of the following terms:
- If someone copies a mag stripe, they can easily replicate that data over and over again because it doesn’t change.
- 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.
- Experts hope it will help significantly reduce fraud in the U.S., which has doubled in the past seven years as criminals have shied away from countries that already have transitioned to EMV cards, Conroy says.
- The introduction of dynamic data is what makes EMV cards so effective at bringing down counterfeit card rates in other countries.
