![]() The Faraday cage blocks a range of radio frequencies- meaning that the radio waves from the RFID scanning device are blocked by the Faraday cage. To answer this problem, a technology called a “ Faraday cage” began being added to wallets. The only way you know that you’ve been targeted is when fraudulent charges begin showing up on your credit card statement. This is a silent and quick process that only involves proximity: as soon as the device is close enough to the RFID enabled credit card, the information is scanned, stored, and stolen. The device stores the information, where the criminal is able to access it. When these devices are turned on and in range of an RFID enabled credit card, they activate the radio frequencies in RFID chips and transmit their information to the device – just like a POS system completing a transaction. With the security vulnerabilities of early RFID, criminals were quick to figure out how to exploit them.Ĭriminals took to building small devices, about the size of a smartphone, that could fit in a pocket or small bag. RFID chips are in about 5% of US credit cards. If you can tap your credit card on the POS instead of inserting or swiping it, then you’ve got an RFID chip. ![]() If you can see a tiny, rectangular bump in the card: that’s the RFID chip. It's the chip and PIN system, which is by all accounts quite secure.Īn RFID chip is typically embedded inside of a credit card, and is only visible if you hold the card up to the light. If you have a credit card with a visible metallic chip in it that you insert into a POS in order to pay – that’s not RFID. So how do you know if your credit card is RFID equipped? Though we’ve been using the word “chip”, it’s likely not the chip you’re thinking of. If someone behind you in line wanted to write your card number down, they could, because there’s nothing protecting your information. Transmitting your card details in plain text has similar security to you speaking your credit card details out loud and having the cashier input the information into their point of sale. In fact, when RFID was first introduced, the card details were being transmitted in plain text. The biggest selling point for RFID chips is that they keep transactions quick and easy: a card can simply be held near a point of sale, the receiver inside the POS picks up the payment details, and the transaction is completed.īut while this seems simple, there’s one big drawback to RFID credit cards: the card details that the RFID chip is transmitting aren’t encrypted. For credit cards equipped with an RFID chip payment details can be transmitted without the card being swiped or inserted. RFID stands for Radio-Frequency Identification, and refers to a chip that has the ability to transmit data. But what is RFID protection, and is it really worth it? What Is RFID? Is It In Your Credit Card? ![]() We see “RFID Protection” as a feature stamped on plenty of wallets – and sometimes we even consider shelling out a few extra dollars for the added security feature. But have you heard of it happening to any of your friends?
