Ask any of the estimated 9 million Americans who become victims of identity theft each year: getting billed for someone else’s credit card charges stinks.
Enter the “radio frequency identification” (RFID) credit card. Designed to provide extra layers of security against identity theft, an RFID card transmits credit card information through radio waves from a chip embedded in the card.. (The cards also have a magnetic stripe on the back so you can swipe it in the traditional way.)
If you’re using a card with an RFID chip, and your merchant has a compatible card reader, you don’t have to swipe your card when making a transaction. You merely hold your card within one to four inches of the card scanner. This practice raises questions as to how safe the technology is and whether you should protect your RFID card with a special wallet or card sleeve. Here’s the skinny on RFID credit cards.
Benefits of the RFID card
Available through credit card companies including Visa, MasterCard, and American Express, RFID cards eliminate certain security hazards posed by traditional cards, but could make you vulnerable to others. According to Denis G. Kelly, author of “The Official Identity Theft Prevention Handbook” and chairman of the Identity Ambassador Commission in Seattle, the security benefits of the RFID cards are threefold: limited card exposure, data encryption and new authentication codes.
