Vanessa here, with AllClear ID. “Smart Cards,” credit cards embedded with RFID chips, are getting more attention as more banks issue them to their customers.
What is RFID – and why is it in my credit card? An RFID credit card has a radio frequency microprocessor inside it that contains your card information. When you check out at the register, you wave your smart card within a few inches of an RFID-enabled terminal. The terminal reads your data, transmitted via radio waves, and completes your purchase. This is the technology used at unmanned tollbooths that let you drive right through.
But unbeknownst to you, you may have one of these cards without even knowing it. RFID cards look like your standard credit card, and some even have the magnetic stripe on the back of the card so that you can also swipe it to pay.
Do RFID credit cards put you at risk for identity theft or fraud? Bo Ho
