This article aims to provide answers for questions regarding RFID blocking / jamming sleeves. Including what they are, how they work and most importantly what is the best RFID blocking / jamming sleeve.
With the rise in contactless card crime many RFID blocking and jamming products have become available, helping combat this theft. Card skimming is where an unauthorized person gets your card details, using an RFID reader near your bank cards. According to the Evening Standard, in the UK occurrence of this theft increased by 128% from 2017 to 2018, and looks to rise.
There are several products available to help stop card skimming, they are RFID blocking wallets, purses, sleeves, and cards. Wallets, purses and sleeves work by acting as a Faraday cage. Creating a screen around your cards which stops electromagnetic fields interacting with the cards. The RFID blocking / jamming cards are the same shape and size as a regular credit card and interfere with signals from a card reader and block transactions.
RFID blocking / jamming sleeves offer some distinct advantages over wallets, purses and cards. The main benefit is that sleeves take up very little space, this is particularly useful for people who frequently travel or spend lots of time outdoors.
What are RFID blocking / jamming sleeves and how do they work
RFID blocking / jamming sleeves are like a pocket that your contactless credit cards slides into. The sleeve produces a Faraday cage around the card so that no signals operating at 13.56MHz can interact with said card. Typically, these sleeves help protect your credit, debit and bank cards along with driving licences. Some suppliers also sell sleeves for your passport too.
The easiest way to check if your RFID blocking / jamming sleeve works is to head to a supermarket with your contactless card inside the sleeve. When coming to pay keep your card inside the sleeve and place the sleeve and card on the contactless payment machine. If the card is read and payment taken the sleeve does not work. If the cards is not read or causes an error the blocking / jamming material works. If payment is taken then the blocking / jamming product is defective and ineffective and should be returned for replacement.
One of the main things to remember when using an RFID blocking / jamming sleeve is that each sleeve is built to hold a single card.
