- How to make a faraday bag, RFID blocking bag, NFC blocking bag, EMF blocking bag, RF shielded bag.
In this video learn to make a DIY faraday bag for your car key FOBs, RFID cards, NFC cards, electronics and electronic Passports that you can use when you are traveling or are out and about. Protect your data and vehicles from theft through RFID readers, NFC readers, Relay Attack devices and more.
Relay attack methods are used in keyless car thefts nowadays outside people’s homes and are also possible when they are out and about. There are proofs of concepts for relay attacks on credit cards too so it’s important to protect your cards and vehicle key FOBs from wireless access without your knowledge. Find links to these demo videos further below.
When you go out, protect yourself by putting your key FOBs, RFID cards and passports in a Faraday bag like the one we make in the video. Similar to faraday cages, these faraday bags block radio frequency signals from entering or escaping the bag.
Unique to our faraday bag is the magnetic close lip to help shield the opening from RF leaks. See how this is done and how we tested our faraday bag in the video.
If you need to, you can also make one to fit your smartphones and laptops too… just like the one I demo for my smartphone.
NOTE:
The copper shielding tape can be sharp so be careful not to cut yourself with it. Use clear packing tape as a protective layer over your bag. Make sure a little tape wraps over the lip of the opening of the bag on both sides (but don't cover the whole magnet on the inside lip). This will help prevent sharp edges on the lip of the opening.

First of all I love your you tube site, frakking creations. I also love the video. Very informative. I did not know that RF acts like water. A small defect in the Faraday pouch can allow RF to escape. Other google sites, suggested using Aluminum foil as a Faraday insulator. I tried it. And much to my surprise, Aluminum foil it wrapped out well, works. The test was to bring your car key near the door and tried to open it. Also tried to turn on you car with and without the aluminum package. Thanks again for the video. You should test a similar aluminum bag. Since aluminum is relatively cheaper.
Thanks for the comments. We appreciate that.
You are correct that aluminum will work too. Several points to keep in mind is that some aluminum foil comes in different thicknesses and the cheap ones are often too thin and tear easily. There is also aluminum tape but note that a lot of aluminum tape use non-conductive adhesive which will cause adjacent tape not to conduct properly to form a good cage. This happens when you tape layers of aluminum tape together and overlap the tape. Just another point to keep in mind.
Please subscribe and share our videos with anyone else you think it will help.
Copper is also denser than aluminum at the same thickness so you may need more layers of aluminum, which could make the cost difference not too different.
In some cases a proper cage may not be enough and signals can actually penetrate the cage if the thickness of the material is not thick enough. That's where it will matter what material is used.
@@FrakkingCreationscould you use an actual piece of copper??
Love it! So easy!!
Thank you.
Unfortunately flipper zero doesn't need the key fob to Access ur car. But this is great for credit cards and phones.
could you tell me does the copper tape work as well as the faraday tape. The price difference is huge. the copper tape is 1/2 price of the faraday tape. Thanks.
I haven't used the tape in the same way to make a Faraday bag so I won't know if the durability is better or worse when comparing the two. The Faraday tape is made using metal infused threads that supposedly can flex more easily, which could allow it to last longer.
In general, for the bag both materials will eventually fail from flexing and use. That's why I came up with the DIY portable Faraday box video. It should last longer but I still have to verify.
idk aboot putting magnets in a bag meant to carry electronics. Might it not be better to double up the bags to go tip to toe like when you're using bin bags for oversized things?
I don't think it will affect too many electronics other than magnetic ones like old audio/data tapes, floppy disks, hard disk drives, etc.
Even cell phones nowadays have MagSafe cases that have metal plates on the back that allow the phone to be attached to a charger or holder that uses strong magnets. The case attaches to the holder using magnetism.
Is there a specific concern you have with what the magnets will damage?
And, it's up to you how you want to create and use your faraday bag. If you want to double up the way you mentioned, that can work too. You will just have to test it to make sure no signals are leaked.
What would we put in them ? And you would likely have to keep it in the bag until the attack happens, which you would never know when… so taking anything out to use until then is risky.
True. Though typically, wouldn't reading the RFID require the crook to be close to you with the scanner? Plus timing would have to be right for the crook to be next to you or near you and ready to read your RFID items when you do take them out.
Faraday bags are not perfect but they do serve some purpose.
So you have a link to faraday tape that is pretty expensive for tape but i didnt see you use any faraday tape, i only seen you use the copper tape so im a bit confused. Where did you use the faraday tape?
I provide the copper tape and faraday fabric tape so that viewers can choose what they want to use. Both can block RF radiation and have adhesive that is conductive to work best (unlike aluminum tape which typically has non-conductive adhesive)
I don't use faraday tape to make the bag here but I do use it to make the faraday book box in my other video. The copper tape is heavier so it may make sense for some to use the faraday tape instead.
It's up to you.
@@FrakkingCreations awesome! Thanks for clearing that up.
Would aluminum tape work as well as copper tape
It probably won't work well, if it works at all. The reason is that the aluminum tape usually uses adhesive that is not conductive.
As you layer one layer of tape on another it's important that they conduct with each other. This will maintain the RF shielding.
Also, the aluminum is less dense than copper so you will likely need more layers.
What kind of plastic should I use for a bigger device? (Oxygen machine approx 2 feet"X1 foot)
Probably a larger ziplock style bag you can get from some dollar stores or camping stores.
If you don't mind me asking, how come you are using it for your oxygen machine?
j'ai essayé avec de l'aluminium adhésif....j'arrive quand même à ouvrir/fermer le véhicule. (juste, je n'ai pas mis d'aimants )
L'aluminium ne fonctionnera probablement pas bien. L'aluminium aime être recouvert d'oxyde d'aluminium, ce qui empêchera la conduction entre les feuilles d'aluminium. Pour avoir un blindage adéquat, chaque couche de métal doit être conductrice électriquement avec les couches adjacentes.
L'aluminium est également moins dense que le cuivre, vous aurez donc probablement besoin de plus de couches.
Avec l'ouverture, les aimants ne sont pas nécessairement nécessaires, mais les couches d'ouverture des deux côtés doivent se toucher pour que les deux côtés soient conducteurs l'un avec l'autre. Sans cela, les signaux peuvent s'échapper de l'ouverture du sac.
J'espère que ça aide.
Can I use aluminum tape instead of copper tape?
It's possible but not ideal. Aluminum tends to have an oxide layer form on it that is non-conductive. Also the adhesive used is typically not conductive too. When you apply multiple layers of the aluminum tape on top of each other, the layers may not end up being electrically conductive and will not work as well to prevent signal leaks.
Copper tape will not oxidize like this and the adhesive used is typically conductive. Best to stay with the copper tape or the shielding tape that I linked to in the video description.
Hope that helps.
@@FrakkingCreations Great, thank you.
Don't worry about an oxide layer on the aluminum tape. Just spray some acrylic lacquer on the surface and no layer will form; also you can stick a layer of ducttape on top of the aluminum tape. Aluminum tape works fine and it's cheaper than copper tape.
