What Are RFID-Blocking Wallets


People in today’s world make most or all of the payments using credit cards. The users keep their credit card details with them and would not give them out to strangers because today there are lots of credit card frauds happening.

Imagine a situation where someone could steal your credit card details just by standing next to you. This is not impossible if you have credit cards with Radio Frequency Identification (RFID) chips embedded in them. RFID is a short-distance electro-magnetic method for transmitting small bits of data.

RFID credit cards allow the user to make the payments by simply pressing the card to a scanner rather than swiping or inserting into the terminal. These types of cards are made for our convenience. A mischievous person can come up to you and scan the wallet in your pocket without you even noticing it.

People have become more concerned about RFID chips  not only due to the credit cards but also the U.S. passports issued from 2006 have these chips that can track your photo and information. Similarly it is everywhere like in Metro cards for quick swiping and much more.

How Do RFID-Blocking Wallets Work?

RFID chips work by using radio waves to communicate. The object, like a credit card has an RFID tag with information, and an RFID reader uses radio waves to read the information from a tag. RFID chips have tiny electromagnetic fields, which allow them to read without having to “initiate” communications. The only thing need is to be in closeness.

RFID blocking wallets or sleeves offer protection against RFID skimming. Radio waves are easy to interrupt and block and that is the working principle of RFID-blocking wallet. They enclose your credit cards in a material that interferes with radio waves. If the wallet is properly constructed to be a Faraday cage, it will block all electromagnetic fields and prevent communication between your cards and RFID scanners.

The question is do you really need an RFID-blocking wallet? If your credit cards don’t have RFID chips, then you don’t need one. Even if you have RFID-chipped cards, the chance of being maliciously scanned is exceedingly low. It depends on how risk-tolerant you are. If you wish to have one go ahead and buy a RFID-Blocking Wallets.
