i usually am active on /g/
so hi /diy/!

how can i turn my wallet (pic is related) into a RFID blocking wallet?

thank you

[Anonymous No.241841]

Put an arduino on it.

[ME No.241842]

To a have place compleatly closed to RFID waves, it has to be electricaly protected. Just put aluminium foil on all the in-sides. How to check if it's works ? Put mobile phone inside and try to call it. If you cannot, you have good made your job. (Sorry for my poor english i'm french ;) )

[Anonymous No.241844]

>>241842
A few corrections:
"in-sides" is just "insides"
"you have good made your job" should be "you have done a good job"

I'm not trying to be a jerk. I just want to help, and I know if I were on a French imageboard I would appreciate help from anyone willing to give it.

yep, a couple of layers of aluminum foil should do the trick

You need to make a Faraday cage around it and have it grounded properly. Otherwise, the radio waves will hit the Faraday cage and go right through it. It needs to have a ground to shunt off the energy.

[Anonymous No.241879]

yeah a completely enclosed netted cage with a ground is the only way to fully work but you could just wrap your card in foil,

[None !nyukka7cK. No.241897]

drink a can of soda, and use the aluminum from that. just cut a piece of it and put it in your money pocket. should work.

[Anonymous No.241898]

Lead lined "film bags", I got a bunch from American Science and Surplus. They are about half as thick as a business card (as big as a binder folder), the material is made to block everything, light weight and is easy to cut.

[Anonymous No.241970]

You might find it easier just to take a razor blade and remove the RFID chips from your credit cards.

[Anonymous No.242411]

>>241865
how should i do this?
walk around with a cable dragging behind me? Oo

>>241897
good idea!

>>241898
will google this!

>>241970
do you have any more accurate instructions on this?
i dont want to break all my cards :D

[Anonymous No.242423]

The card must be completely enclosed by conductive material in order to block all signals. RFID is weak enough that you don't need any more grounding than is already provided by contact with your person or clothing.

If your wallet doesn't clip or zip closed on all three open sides, it can never be properly RFID-blocking.

When an RFID transmitter is only partially enclosed, the signal will actually be amplified through any gaps in the enclosure. These signals could even bounce off nearby objects and still be detectable by a receiver in a "blocked" direction.

I kinda wanna make a Faraday cage wallet now. I can have a chain that attaches to my wallet, and whenever I go to sit down somewhere I can ground it by hooking it to a metal chair or attach a spike and ram it into the ground.

And whenever someone asks me about it I can go on Stallman rants about how RFID is like Hitler and AIDs combined.

ok... good to know!
so can you recommend me a wallet to buy that already has that functionality? i saw quite many, but i dont know which one are good / actually work.

thanks :3

Enjoy having your every move tracked by the government.

[Anonymous No.242865]

For me the biggest disappointment about RFID is that whenever people discuss it or think about it all they worry about is blocking it so people can't steal it. I've seen people talk about the evils of RFID for 5 minutes when it struck me that they had NO idea what RFID is, and just assumed it was a global tracking-chip that could be used to subvert people's actions or deliver lethal jolts of electricity to murder people remotely.

RFID is rad as fuck. The hobbyist uses of it are fun and easy to implement. But when it comes to the manufacturing/storage sector those things are a godsend. Scanning chips is soooooooo much cheaper than any other system of inventory management.

Long story short RFID is rad and people need to use it more.

[Anonymous No.242872]

>>242865

>inventory management

Sounds like what the government is doing. You must be a plant.

[Anonymous No.242876]

>>242872
I know you're trolling but basically here's the truth: I love the inventory management shit because those semi-passive RFID chips make me rock hard.

If I didn't have to order 1000 of the things at a time I would already have chipped everything small and easily misplaced in my house and programmed a wireless locater. I would do that shit TONIGHT.

[Anonymous No.242882]

Can someone please explain to me what is in your wallet that uses RFID in the first place?

[Anonymous No.243035]

>>242882
Credit cards, (allegedly) certain denominations of cash, drivers licenses, national ID cards and passports.

I have heard that some companies have been putting them in business cards so they can track who enters their building and have an idea of who they are there to see before the person even speaks with anyone.

[Anonymous No.243040]

>>242876
I'm with you bro.
I tried to figure out a way with my boss to get RFID for inventory management but for what we keep in stock, the tags cost relatively too much.

I tried to educate a colleague about how RFID isn't some nefarious global-tracking chip and that I told him I could buy RFID tags and related electronic components right now if I wanted. He said "yeah well, the information on how to use them is probably secret and only available to the government." I said no, you can download the datasheets right now. He remained pretty convinced that RFID is bad and that's that.

[Anonymous No.243139]

So, I guess I'm a bit confused reading the thread. Why do you need a ground for a Faraday cage to work? Airplanes get hit by lightning all the time and it makes a Faraday cage at 32k feet, so why do you need a ground for your wallet?

Second, the only reason you might want to stop RFID is because of identity theft. They have gotten to the point where they can mount an antenna on a car, drive down the street, and get the RFID info on people's passport without ever being seen or heard from. IDK what's on there, but if history serves, it's usually not good for other people to know that stuff.

[Anonymous No.243176]

Yeah, its cool until its mandatory to carry one around, in what form doesn't matter. So you are at a point where you cant even buy anonymously toilet paper because of "safety reasons" since you need one to pay for basic shit.

The government really doesn't care, aren't organized enough to do anything about it, nor want to spend the money to do anything about it.

Corporations on the other hand think this shit is a gold mine and are pushing it to the extreme. Corporations normally have more info about you than the government could ever dream of. Why? Because it makes them lots of money.

And yes, corporation are a big danger, but since they lobby in our government like no other group, have politicians on their paylists and influence the media it really doesn't makes a difference who is fucking you in the ass for the sake of controlling people.

Case in point,

Getting my driver's license required me to give the following info or do these tasks,

Social Security Number
Name
Birth Date
Home Address
Phone Number
Pass Eye Exam
Pass written test
Pass driving test
Photo taken
Blood type (optional at the time, but is no longer even asked anymore because of privacy issues, lol)

Getting a credit card,

Social Security Number
Name
Birth Date
Home Address
Email Address
Phone Number
Give employment info
Submit to a credit check
Must sign a privacy policy that gives the company rights to sell your info to other companies.

Car/health/home insurance,

Social Security Number
Name
Birth Date
Home Address
Email Address
Phone Number
Give employment info
Consent to a credit check
Submit to a physical examination
Answer questions about family health history
Allow school records to be checked
Must sign a privacy policy that gives the company rights to sell your info to other companies.

Home Loan,

Social Security Number
Name
Birth Date
Home Address
Email Address
Phone Number
Give employment info
Submit to a credit check
Allow school records to be checked
Must sign a privacy policy that gives the company rights to sell your info to other companies.

Those last 3 are in bed with each other and trade/sell/buy info with each other on a regular basis. This also means that if you have a credit card and are purchasing anything they can sell that info to anyone. For instance, if you use free email services like Hotmail then you buy something from Newegg or eBay, suddenly the ads on your hotmail page turn into items similar to those you just purchased. Pretty slick huh?

>Stasi

What does that have to do with this? The Stasi were removed over 20 years ago because it was illegal.

[Anonymous No.243201]

>>243199
Might as well add Bank Account to that since you need to give the same massive amount of info and histories. The banks have a pretty big system for it even between different banks. Also, if you have a debit card, it is the credit card companies that handle the operation of the debit card. Thus, they too get all your info even if you don't actually have a credit card.

My debit cards has the Visa symbol on it for instance.

Why so dense?
They where removed because the GDR collapsed, it only shows what a government is able to do if they are willing, its exactly the shit that most people think is impossible. Imagine what they could pull off today where its far easier to gather informations and tracking people without having an agent after them all day long, history repeats itself. Just look at the US after 9/11, if they can somehow justify violating your rights they will.
