RFID Credit Cards: Should You Worry About Protection? | Bankrate
How secure are RFID credit cards?
RFID credit cards are considered to be as safe as EMV chip cards, and data theft concerning RFID cards is uncommon. This is because of how these cards transmit information and what information is shared.
Unlike traditional credit cards, RFID cards use one-time codes to complete each transaction. Every time you use your RFID card, a new code is created, thus making it more difficult for your information to be compromised.
Do you need RFID-blocking protection?
Because RFID credit cards work via radio frequencies, some concern has been drummed up that a card reader could pick up your card information without your knowledge. For this reason, there are quite a few products on the market, such as sleeves and wallets, that claim to have RFID protection.
However, these products are not necessary to keep your RFID credit cards safe. For a person to compromise your card information, they would have to get very close to you, have a card reader that could pick up a signal and have no barriers between the card and card reader.
While it is technically possible for a thief to find a way to skim your RFID card, they would have to work quite hard to do so.
