Hello, and welcome to your “2-Minute Money Manager.” I’m your host, Stacy Johnson, and this answer is brought to you by Money Talks News, serving up the best in personal finance news and advice since 1991.
Today’s question comes from Al:
“Do high-frequency anti-theft cards (i.e., “shield cards”) work? Are they as good as RFID-blocking sleeves?”
Are your credit cards safe?
Imagine a pickpocket so skilled, he could steal your credit cards from a few feet away without you feeling a thing.
According to some hawking RFID protection, it’s possible. In fact, they say, anyone can theoretically pickpocket your plastic with an RFID card reader, no skill required. That’s because some credit cards are continually broadcasting information. All a crook has to do is own the equipment that captures, or “skims,” it.
RFID stands for “radio frequency identification.”
Originally used to track inventory, RFID transmits data through the air so it can be read by nearby contactless readers. The technology has since been used in credit cards, passports, driver’s licenses and more, although it’s more prevalent on European credit cards than American ones.
Is RFID the same as a chip card?
Credit cards with digital chips are called EMV cards (short for the companies that developed it: Europay, Mastercard and Visa.) These are not the same thing as RFID cards. (Note that to use an EMV chip card, you insert it into a reader, not just get close to one.)
To see if you have an RFID card, look for radio waves on the card — the same sort of symbol you see on your smartphone or computer when you’re hooked up to Wi-Fi.
While credit cards with chips are now ubiquitous, RFID cards are much rarer.
Is RFID as dangerous as they say?
RFID-blocking products are a textbook example of the expression “fear sells.” While millions of us have been subjected to credit card and ID theft, I did a web search and couldn’t find a single example of credit card theft by RFID skimming.
There are good reasons for this. First, although RFID cards may be transmitting information, that information is likely to be encrypted, so it’s unusable.
More to the point, it’s much easier for a crook to go online and buy hundreds of credit card numbers stolen in a data breach than to brush up against individual people in hopes they have an RFID-enabled card in their pocket or purse.
In short, when it comes to credit card and ID theft, RFID skimming is the least of your worries.
A cheap solution
If you’re still concerned about RFID theft, there’s a less elegant, but just as effective, prevention device: aluminum foil. Wrapping your cards in foil defeats the skimmer. Some say it does so even more effectively than products designed for the purpose.
I hope that answers your question, Al. I’ll see you all next time!
