What Are RFID-Blocking Cards and Do I need them?

Credit card numbers are sacred. We would never give them out to strangers because credit card fraud and stolen identities are rampant problems. But what if someone could steal your credit card information just by standing next to you?

It’s possible if you carry a credit card with an embedded RFID chip. RFID credit cards let you make payments by touching the card to a scanner rather than swiping across or inserting into a terminal. They’re designed for convenience. Now imagine if someone walked up to you and “scanned” the wallet in your back pocket, or purse, without you realizing. This can be done and criminals could copy the RFID data and create a clone of your credit card -- unless your card is protected by an RFID-blocking card.

People have been concerned about RFID chips for a while, and not just with credit cards. All US passports issued after 2006 have RFID chips that track your photo and information. Metro cards have RFID chips for quick swiping, and dogs are implanted with RFID chips for tracking. RFID chips work by using radio waves to communicate. The object, such as a credit card, contains an RFID tag with information, and an RFID reader uses radio waves to read the information off that tag.

The key is that RFID chips have tiny electromagnetic fields, which is what makes it possible to read one without having to “initiate” communications. The RFID reader just needs to be close enough to get within the field. That’s why a criminal could scan a card through your pocket or purse. And yes, people in the real world have been scanned like this.

Fortunately, radio waves are relatively easy to interrupt and block, and that’s how an RFID-blocking cards work. They simply disrupt the RFID signal. If a wallet or purse is properly protected, it will block all electromagnetic fields and prevent communication between your cards and RFID scanners. These can easily and inexpensively be accomplished by using RFID-blocking cards. Why cards versus sleeves or even wallets. This is simple. Sleeves fall apart and get expensive to replace on a constant basis and wallets, well I love my current wallet that was very expensive and I don't want to spend money on a new wallet!

For me the solution is simple. RFID Blocking Cards by SmartProduct are extremely affordable and well worth the value. You get 1 pack that contains 2 card protectors and the company has an awesome deal going on right now, that runs about the price of  two Starbucks coffees. Just slip your card into a sleeve, then slip the sleeve into your wallet—and they come with a full money back 5 YEAR guarantee!

Anyway, I hope that you learned a little about RFID blocking and why you need to integrate this into your life. RFID Blocking Cards by SmartProduct are available at Amazon at
