The latest credit cards have a new feature: a half-inch square on the card’s face that looks like a mini circuit board. The square is a small computer chip called an EMV. The acronym stands for Europay, MasterCard, and VISA, the developers of the technology. Over the next several years, these chip-embedded cards are expected to replace the familiar magnetic strip technology on cards that you now swipe at point- of-sale devices. When you use your EMV card, you’ll need to “dip,” or insert, it into a new type of reader.
Why the change? The new chips are expected to improve credit and debit card security. Data on cards with the older technology is much easier for crooks to steal because the information on the magnetic strip is static and can be copied. As a result, a thief can use your card for multiple fraudulent transactions. Cards with the new chip are different. Every time you use an EMV card, the chip creates a unique transaction code. As a result, the newer cards aren’t as useful to counterfeiters and card thieves.
