In September 2016, Visa reported that the U.S. switch to credit cards that include a security chip resulted in a 47 percent decrease in retail fraud. This effectiveness, however, led to a 33 percent increase in online-fraud attacks, according to the credit bureau Experian.
It’s no surprise. When other countries switched to chip credit cards, which protect your financial information better than do credit cards that have a magnetic stripe, the countries saw online fraud tick up as criminals turned their attention to easier prey.
You should keep in mind that the chip that’s in your credit card doesn’t protect your information when you shop online, says Michael Bruemmer of Experian. John Breyault of National Consumers League says you might want to use an online-payment tool instead of your credit card when you shop online, so you avoid having to share financial information with different sites. Some credit-card issuers also provide one-time numbers that you can use to make purchases. This ensures that even if a hacker were to snag the number, your data would remain safe.
