Digital crimes are on the rise. Protect yourself from lurking thieves with RFID blocking sleeves for your wallet.
Picture this completely common scenario: you’re sipping your coffee at a crowded cafe, completely unaware that a nearby cyber-criminal is scanning your cards using a concealed skimming device. These devices can easily capture your card information through wallets, purses, or backpacks, leaving you with an emptied bank account and a sense of violation.
In the modern age of technology, convenience often comes hand in hand with vulnerability. Our wallets, once home to a simple stash of cash and cards, have evolved into digital repositories of sensitive information. One way you can protect your assets is with RFID block sleeves. Imagine a cloak of invisibility for your credit cards. That’s essentially what RFID blocking sleeves are – tiny sheaths of security designed to protect your contactless cards from remote theft.
RFID, or Radio Frequency Identification, is the technology behind those tap-and-go credit cards that make transactions lightning fast. However, this convenience comes with a downside. Criminals equipped with RFID skimming devices can remotely extract information from a banking card or key fob without your knowledge, leading to unauthorized transactions and theft.
How Does a RFID Skimmer Work?
An RFID card skimmer works by detecting the presence of an RFID card or key fob nearby, initiating scanning as the victim approaches with their RFID-enabled card. These cards communicate wirelessly via radio frequency signals due to a built-in chip and antenna. When within the range of an RFID reader, the card responds to emitted radio signals, transmitting stored data.
The skimmer, posing as a legitimate RFID reader like those at payment terminals, intercepts these signals and captures them via its antenna. The stolen data is then stored by the skimmer. Subsequently, criminals can exploit this information for unauthorized purchases or even duplicate the victim’s card onto a blank RFID card or duplicate key fob, allowing theft without the owner realizing anything is missing.
How Do RFID Blocking Sleeves Work?
At its core, RFID blocking sleeves are a barrier made of special materials that obstruct the radio frequencies used by RFID technology. These materials typically consist of a combination of metals – aluminum, copper, and nickel – woven into a fabric or film.
When your card is safely nestled inside the sleeve, these metals create a Faraday cage, a term derived from the legendary scientist Michael Faraday. This cage acts as a shield, preventing electromagnetic fields from reaching your card and thus safeguarding your data from prying digital hands.
Tests have revealed that while RFID blocking sleeves and other shielding devices aren’t entirely foolproof, they do significantly decrease the maximum distance for readability, reducing it from roughly 1.5 feet (50 cm) to 1–2 inches (3–5 cm).

DIY RFID Blocking Sleeve
Aside from wrapping your cards or key fob with tinfoil while out, there are easy and cheap ways to create your own DIY RFID blocking sleeve at home. You’ll most likely have all the materials laying around anyway.
- Aluminum foil or RFID blocking fabric
- Clear packing tape or fabric glue
- Scissors or cutting tools
- Ruler or measuring tape
- Contactless card or device you want to protect (for sizing)
- Measure and Cut: Start by measuring the dimensions of the card or device you want to protect. Add about 1/2 inch (1.27 cm) to each side for seam allowance and ease of insertion.
- Cut the RFID Blocking Material: Use the measurements from step 1 to cut out two pieces of aluminum foil or RFID blocking fabric. These pieces will serve as the front and back panels of your sleeve.
- Prepare the Panels: Lay one panel flat on a surface, with the RFID-blocking side facing up. Place the contactless card on it to make sure it fits comfortably within the dimensions. If using aluminum foil, ensure that the reflective side is facing the card.
- Attach the Panels: Apply a thin, even layer of clear packing tape or fabric glue along the edges of the panel that will form the sides and bottom of the sleeve. Make sure to leave the top edge open for inserting the card.
- Seal the Sleeve: Place the second panel on top of the first panel, matching up the edges. Press down firmly to seal the sides and bottom of the sleeve. If using tape, make sure the tape adheres securely. If using fabric glue, allow the glue to dry completely for a day or two.
- Insert and Protect: Open the top edge of the sleeve and slide your contactless card or device inside. Ensure that the card is fully enclosed within the sleeve and that the top edge is securely closed.
- Test the Sleeve: Before using the sleeve, test its effectiveness with an RFID reader or you can try putting your key fob into it and see if you’re able to unlock your car through the sleeve. If it does not work, your homemade RFID blocking sleeve works successfully. If large enough, you can also try putting your cell phone into the sleeve and calling it. It should not be able to receive any service if your sleeve was made correctly.
