Aluminum Foil for RFID Protection?
Вставка
- Опубліковано 8 сер 2024
- In this video, I test to see how well aluminum foil works for RFID protection. If you want to try the coolest and super effective RFID-blocking card, check out the Survivor Symbols card at disasterpreparer.com/product/....
What I have found effective is that you can put a large piece of foil in the paper money pocket of your wallet and it effectively surrounds all you cards in a foil taco when it is closed.
try sandwiching the 4 cards between the aluminum foil
Duh
Did you try sandwiching all of them?
Not sure why he didn't try it in this circumstance he had it already there. I was wondering the same thing.
Checkout his part 2 video for his revised test wrapping multiple cards in one foil...hint - it works!
Just to annoy everyone lol
since aluminum works, you could make a little "sleeve" using aluminum tape wrapped around your card.
O really? No one mentioned that part 🤣
Yeah basic physics. How hard can this be to understand?
That's what I do
Interesting...thanks for showing your results!
You're welcome!
Great video on a good question from a viewer. I was wondering the same thing.
Wonderful video. Well done considering all relevant situations. Thanks
I like this channel, we need to share it with others...
I know. It's my "go to" channel when people talk about faraday cages or surge protection.
@@HabitualButtonPusher yep same here!
@@Saint696Anger Yep, same here!
Dr. Bradley, I love what your bringing to the tube. What could somebody use to shield themselves against an offensive FLIR targeting system?
Hmm... I'd have to think about that. Warm-blooded creatures are of course sources of IR radiation, so you'd have to envelope yourself to prevent that release from being seen. It'd be like trying to hide a flashlight that's always turned on. You'd need to cover yourself in something that prevented the IR energy from being seen. I've seen posts of covering yourself in a space blanket, and I suppose that might work (sort of), but I think it would be difficult. It's my understanding that glass won't pass themal IR, so a large glass shield (I know, not practical) would in theory do the trick. Sorry, I don't have a better answer.
Newer combat clothing is coming out that blocks a lot of IR but your exposed body parts remain an issue. I have a better idea why dont you set off an EMP to stop you from being watched
Very informative video.
Hey Doc,please help!
I stack 3 RFID cards in my office ID card holder to scan through three different gates every day, they are interacting with each other and not working, how to fix this?
Can you reproduce similar results of the Vaultcard by stacking multiple sheets of aluminum essentially making it thicker? Would the increased mass make a difference or increase the effectiveness?
I'll try this today when I do the experiment of wrapping the stack of cards with foil. Stay tuned...
How can we tell if the thick pieces of aluminum protect against a RFID reader. I'm using heavy duty foil with multiple thicknesses.
It's interesting to test one card with the aluminum foil facing the scanner but not with a few cards.😅
Exactly! That was my comment exactly. What fool would put the foil in front of the card? Of course you’d have it behind the card. Even if you put foil in the cash part of the wallet there is no way the scanner would get through it to scan the card.
how about stacking multiple cards with aluminum foil in the bottom? can it protect it? thanks!
I'm curious if the scanner can read from the edge of the wallet; esp. the top or side near the RFID.
What if you thicken the foil around several cards? Does this protect?
Thanks!
try inserting a piece of aluminum foil of the size of a bill in a bifold leather wallet
I have a big mundi rfid wallet can I put that vault card in one place of my wallet and it protects the whole wallet. The wallet is medium size with lots of pockets for cards and a zipper pocket for a phone. Other question how would you protect your phone from thieves I hear people using their phones now as credit cards. Any suggestions?
Great information too
What can disrupt heterodyning, or elf/uhf frequencies?
Nice test on the foil. If someone has a limited budget ,That would get them by. I'm impressed by the Vault Card. I Don't know if some passports have RFID chips in them. But one Vault card in a passport case would stop a reader.
Thank you for testing these things.
You're most welcome.
well so if you wrap EACH CARD with foil will work right?
I am wanting to make a purse with a protective layer to keep my phone and cards from being read. Do you have any suggestions on what type of liner to use to go in between my fabrics? Aluminum foil, silver lined fabric, etc........?
Assuming you have a smartphone, you really don't have to worry about it being read. The security in the phones is quite sophisticated. Blocking the EMF from the phone is a different problem, however, and one that I plan to address in the next few weeks. As for protecting the credit cards, you could simply keep a VAULTCARD with your other cards (see disasterpreparer.com/?product=vaultcard). You can also purchase an RFID wallet. They also sell RFID purses, but they might not be to your liking. If you choose to make a purse yourself, you'd want to find a conductive cloth to put between the layers. I sell a cloth that would work well (see disasterpreparer.com/?product=emp-cloth), but there are many other conductive cloths on the market.
Cool video, would be curious to see a repeat with the foil insulated from your body as it would be in a wallet
What if you line your purse or bag with tin foil...would that do the trick too?
Are you planning to do more videos like this? I am interested on the imeetu RFID Credit Card Holder, Small Leather Zipper Card Case Wallet for Women
Would you be able to test it out?
What about JUST putting wallet in refrig or freezer for protection ?
very useful
Gostei da explicação.
What about the rfid on Michellin and Goodyear tires? Any ideas on jamming or blocking that threat?
What are you up to that you're so worried about being tracked by the government?
@@forrestunderwood3174 It's not worry. They ARE tracking everyone. It is called tyranny, fool.
any reason why you didn't test multiple cards stacked inside the foil flap (the foil folded to cover front and back)? good info, though!
I believe it would work fine to sandwich the cards. I just didn't think it was a particularly practical configuration for most wallets. I'll double check tomorrow, and if it doesn't work, I'll post a reply to you. I'm confident it would work.
@@disasterprepper thanks! i saw your reply to a similar comment after i posted mine.. lol.
Thanku. Can magnets prevent readings? I know heavy but just wondering
No, I wouldn't think so. Magnets are not time varying, so they likely wouldn't have any effect on the RFID reading.
@@disasterprepper I've heard a strong magnet can demagnetize/deactivate the tape on the back of the card, so not a good idea. Do you have a promo coupon code for ordering? Thanks for the demo!
Excellent. Is there such a thing as a rfid protector that covers a laptop (if you leave it in your trunk)? I heard that theifs ( there are apps out there) are using apps to track electronics in cars ( esp trunks of car). How can you protect your lap top IF you need to leave it in your trunk?
There are RFID cases and sleeves for laptops that would prevent remote detection while the laptop was in the trunk. Look around on Amazon, and I think you'll find some. I'm not sure that laptops when closed would actually emit any signals though, I haven't checked that.
Why would your laptop be turned on when it's in your trunk???
What about three layers of aluminum foil on each side of your credit cardS?
What if you line a wallet with aluminum foil would that stop the RFID reader
I suspect it would work fine, just like an RFID wallet. The problem might be whether or not the foil lasted without getting messed up.
One factor you didn’t take into consideration is using the stronger portable readers that can read info from 3-6 feet away.
The government can read them 100 feet away.
😲 Thats very scary.
Lots of claims above and no links to proof.
can i just have a foil bag and go shoplift a store discretely and when i exit the alarm wont go off? just a question
Yes you can, but if you do it in California, nobody would pay any attention to you in any case.
Just ordered thx
I'm guessing you probably ordered from Amazon. Just FYI... I managed to get a discount by ordering a large batch of VAULTCARDs, allowing me to sell them at a significantly lower price on my website disasterpreparer.com. The first batch should be in next week.
thank you !!!!!!!!!!!!!
... why can't you just wrap a stack of cards -- like just put all three or four of them *inside* the foil...?
One of my credit cards is made of metal. What's that all about?
Why didn’t you wrap all four cards together in foil? Would that had stopped rfid?
Kindly check out the second video on other foil combinations.
Hey - what effect if upper and lower of a stack had foil ?
I suspect that would work fine. It just didn't seem practical for most wallets.
Checkout his part 2 video for his revised test wrapping multiple cards in one foil...hint - it works!
i opened the seams in my wallet and then sandwiched 2 rfid blockers on each side and then glued them back up.
this way i was able to get a RFID blocked wallet years back without paying the premium price
nowadays the price ofc is much cheaper.
No excuse for the card companies not providing it with the card to begin with. They cry about losses from scams yet they encourage it.
so what is the point of doing that to the credit cards...once u use one the information is there for grabs...please educate me thanks.
Interesting. I presume that putting the four cards in the folded aluminum foil would work. And maybe just between two pieces.
I suspect neither would be as good as what I presume is active jamming from the Vault.
Yes, I didn't test that because I thought it's not practical for most wallets, but I suspect that would work fine.
@@disasterprepper the aluminum acts as what is called a faraway cage... If you put as many cards as you want inside of an aluminum enclosed cage, the field inside would be zero... In other words you could not read the cards inside of the enclosed foil...
@@russellsmith9509 Actually that's "faraday" cage.
So did you sell EMP Storm to another company? I see there is an EMP Shield website and UA-cam channel (with someone else on the videos), and I don't see it on your normal site anymore. If EMP Shield isn't your product it sure does look exactly like yours and has the same certifications.
Hi Devin, no I didn't sell the EMPStorm. I had to suspend the project while I work through a health issue. I hope to return to it soon.
@@disasterprepper Well, I pray you heal up soon. That EMP Shield looks almost just like EMP Storm, it's weird, and do you know if there is much difference between the two? I would prefer to order EMP Storm, I was just surprised to see something similar out there.
@@Devin82m Their product is designed differently, so I would encourage you to reach out to them to discuss the specifics. I think they've had their product out for a couple of years now.
thx
My waller has a 6 slot stack cardholder, would 1 VAULT card prevent it from being read? By the way, excellent video, I am sharing with my friends.
Yes, a single card would protect the stack. I'd suggest putting the VAULTCARD in the center of the stack, but based on my tests, it would work anywhere in the stack.
Hi, instead of wrapping individual cards, why not line the inside your wallet with foil?
There is no one right way. I'm sure you could line your wallet, since that's essentially what RFID wallets do. You might also check out my new Survivor Symbols card (disasterpreparer.com/product/survivorsymbols/). It's an effective solution that's kind of cool.
@@disasterprepper Aluminum credit cards.
Fold the foil into the shape of a dollar bill and place it in the wallet like a bill. In a trifold wallet. When you close the wallet, it incases the cards in the wallet..?
Would have shown how it worked putting the aluminum foil inside an actual wallet putter wall and once folded to see if would still protect 😊
getting that special card on your website would be a great idea
I checked with the manufacturer. It looks like I have to order 50-100 to get discount pricing. If I can get enough folks interested, I'll order a bundle and put them up on the website at a discounted price.
@@disasterprepper I'm game for at least one. Looks like less than $35 each on website.
What about a alum. tin?
Any kind of conductive material works fine.
You didn't put more than one card inside a folded aluminum foil. I was waiting for that one test from the beginning. I guess the results would be great.
I only had one card that could be detected, so putting more than one credit card would only increase its thickness. It wouldn't make any difference in the case of the foil.
I could smell that he pushed for the vault-card. That's why he did not do that experiment.
@@Phil27939 Perhaps, but I don't mind. I'm going to buy a vault card from him bc he's put a lot of work into helping us.
I was hoping you would wrap several cards in aluminum foil in a taco style.
For the aluminum foil to work, you needed to put it on the bottom of the cards, between the cards and the reader. Why didn't you do that?
Actually, for the aluminum foil to work it has to cover one's whole head.
What about an aluminum Pop can? I’d like to make some RFD wallets. So I was hoping that the aluminum pop can would work.
What if I lined the exterior of my wallet with al foil?
That would probably do well in terms of shielding, although it might tear easily.
I was wondering why you did not rap a pile of cards with the foil? It was strange to me that you dint.
You didn't show us all those cards between the _folded_ foil- I'm sure that would've worked.
My observation here is that by holding the aluminum foil in your hand with the card, your hand is acting as a ground for electricity.
With your hand as a ground for electricity, the foil works.
Does the foil work ungrounded (without your hand)?
Yes, it works fine without my touching it. The reason is that a conductor reflects and absorbs far-field RF energy even when ungrounded.
@@disasterprepper thank you for replying to my question!
Putting the foil on top of the card is genius!!!
You didn't try to put all the cards in the wrap of aluminum foil.
There's a second video in which I do various combinations.
The one test that you did not show was wrapping around ALL the cards.
My bank card is inside the bank sleeve they gave me, three layers of foil on both sides and a paper cover.
What if you put the foil on the bottom side? This would simulate the outside dollar bill pocket of a wallet having tin foil in it and the wallet being foldered over in 1/2 and zippered closed if it has zipper. So the complete wallet is wrapped in foil when the wallet is closed.
I can't help but sing Weird Al's "Foil"...
Was this video sponsored by that “volt” (sp?) card vendor? Because the video felt like an infomercial to me.
it'd be nice if there's a longer vault card for those longer wallets like clutches and other purse wallets
Also, I was expecting you to have flipped the cards so that the aluminum is on the bottom to see if that makes a difference
That's a good idea.
tape two together ^_^
I have $18 in my bank and I'm worrying about this
Ill just get a foil wallet
Why didn't you put all the card inside the aluminum foil that fold which will surround the entire card to see you only did one Not all inside the aluminum foil.
I'm sure that would work fine, but it didn't seem practical for most wallets. Even so, I'll check it tomorrow and post the results.
@@disasterprepper Thanks
Junk food wrap works...tell you kids not to throw it..
You didnt test the cards in the same way as the one your trying to sell!
You put the valt card on the bottom but the foil on the top of the stacked cards.
I find this very deceptive!
there is a problem with your testing. when you tested a single card with foil, you testing the white card ONLY. you did not test a real credit card with foil. you did test a stack of cards mixed but you never tested a single real credit card with foil only .... your mistake was assuming that the white test card was the same exact tech as the other cards with the logos on it
Real credit cards won't trigger the reader, only the white card will do that. It uses the same exact technology as a credit card but is tuned to the reader.
USE CASH, YOU MUPPETS!
Really? So I'll just make tinfoil card sizes and put them in my wallet. And a dollar sized tinfoil so it's in the wallet as it closes. If these expenses RFID cards are foil, then my idea should work.
Nice sponsored
So why don’t you put the foil next to the reader? Why are you putting it last? They’d be scanning the foil side, not the card. What dope would put the foil in front of the card?
This doesn't make sense. Why would you put the card toward the sensing unit with the foil in the opposite side? You should put the foil toward the sensing unit not the card.
