Everything You Need To Know About EMV (aka Chip-And-PIN)

Posted by Zach Walker on Feb 26, 2014 7:13:00 AM

Chip_and_Pin_Cards-291287-edited

What Is EMV (aka Chip and PIN)?

When you see the words “chip technology”, they’re talking about credit and debit cards with an embedded microchip that contains unique cardholder information, including the cardholder’s name, card number and expiration date. Instead of swiping your magnetic stripe card and signing to authenticate, the new point-of-sale (POS) machines will read the chip on the card and then ask the cardholder to enter a PIN code to authenticate. Replicating the chip itself is far more difficult than replicating traditional magnetic stripe data, making card duplication much harder.
