How to block/kill RFID chips

How to block/kill RFID chips
In this Instructable I will describe different ways to block or kill RFID tags. RFID stands for Radio Frequency Identification. If you do not know about this technology yet, you should definitely start familiarizing yourself with it, because the number of different devices that utilize these types of tags is growing exponentially.

RFID chips are very similar to barcodes in the sense that a certain amount of data is contained within them, and then transmitted to a reading device which then processes and utilizes the information. The major difference is that barcodes have to be physically visible to the reading device, which is usually only able to scan them at a distance of a 12 inches or less. RFID tags, on the other hand, do not have to be visible to the reading device. They can be scanned through clothes, wallets, and even cars. The distance from which they can be read is also much greater than that of a barcode. At DEFCON an RFID tag was scanned at a distance of 69 feet, and that was back in 2005, the possible reading distance now is probably much greater than that.

There are a few different categories of RFID tags, but the most common ones, and the ones we will be dealing with in this instructable, are the "passive" type. Passive RFID chips contain no internal power supply. They contain an antenna which is able to have a current induced in it when within range of the RFID reader. The tag then uses that electricity to power the internal chip, which bounces its data back out through the antenna, where it will be picked up by the reader.

For more information on RFID tags check out the wikipedia entry.

Step 1Reasons for blocking / destroying RFID chips

Reasons for blocking / destroying RFID chips
The main reason someone would want to block or destroy RFID chips would be to maintain privacy. In the last step I explained that RFID tags can be read from very long distances. The potential for abuse of this technology grows as more and more products and devices are being created with these tags built in.

Companies are getting consumers to blindly accept many RFID tagged products with the promise of convenience; however, most of the devices that contain RFID tags don't really need them. The tags may save a few seconds, but sacrifice an enormous amount of privacy and security. It is now possible for someone, with relatively simple equipment, to walk down a busy sidewalk and pickup the personal information of people carrying RFID tagged devices, without them even knowing.

Being able to block or destroy these chips allows people to decide what type of information they are willing to sacrifice for convenience.

Anyone remember the tape head degausser that Radio Shack used to sell? I wonder if something like that would work??

Seems easy enough to make.

Also, FYI, stores like walmart will have RFID sewn into clothes. Ya know those 'alarm' scanners that you walk by to get in/out of the store?

Those could be easily used to determine who comes into the store, who leaves, their criminal and financial records, RACE, etc. And problems could easily ensue.

Let's say you were a stupid kid that got caught shoplifting at age 18 and a day. Walmart could determine by any RFID chip on your ID or clothing you bought with a check, credit card, or debit card, that you were once convicted of theft.

They could instantly sound alarms and flashing lights announcing over the loudspeaker - 'Convicted Shoplifter!' and BAR you from the premises!

Let's say that you went shopping in a rather ahem bad neighborhood (or any really). Let's say that the shop keeper needed a tax write off. You get close to his scanner, and his recorder gets your info. He then steals your information, uses you as a tax write off, and the IRS comes beating at your door. While this happens, the shopkeeper is on his way to his home country...

Anyway, does anyone know what coil those RFID chips use? I am sure is is a fairly standard RFI choke of sorts.
Knowing the size, shape, number of turns, there is a way to determine the amount of power it can generate.

Please note: The government will require you to have one. It will make it a major crime to tamper with it or disable it - similar to those breath machines drunks have to put into their cars or the ankle bracelets home incarceration people have to wear. If your RFID chip fails to 'phone home' for more than a specified time, they will prevent your car from starting, your accounts will be frozen, and a capias will be issued for your arrest.. Soon, credit cards won't work without it.

While it is fanciful to dream about having privacy, it just isn't going to be as easy as everyone thinks.

You can play now with the ability to disable them, but in real life, all governments will see this as a gold mine to control everyone.

How many of you can really live in total isolation? Nothing electrical. No ability to buy anything. On the run all the time.

This is coming. Best way isn't to destroy the chips but to reprogram them with the information YOU want them to have.

Anyone got a box of spare RFID chips that are blank? And a program machine? And a guide on how to program or reprogram one?

That will be your best defense. Until they get you for having a fake identity...

I'm not so certain that privacy is a valid issue. The guys conviction for shop lifting should be public record and should have life long consequences. When people try to fly the privacy flag it is often or almost always because they want to be able to get away with something. Yes the guy that cheats on his wife just hates the idea that his car might log every stop it makes and that that information was easy to access. The guy that cheats on his wife is also far more likely to cheat the company he works for. When facts are shielded then aren't the employer's rights compromised? If a salesman comes to my home with a product should I not be able to tell if he has had honesty issues or is in debt so deep that he will do most anything to get by? Freedom and the free flow of information go together.
May 28, 2012. 12:14 AMTreknology says:
I think privacy is a really big issue. I don't care that my neighbors know my income, my sexual behavior, or my upbringing history.

I do care when the government has this information. Time and time again, democratic or dictatorial, governments have demonstrated that they cannot be trusted with any of this information. On the other hand, I'm perfectly happy for my medical history to be an open book because it shows the negligence and ignorance of those who are living off our tax money in the name of "public health".

There are many people out there who can't keep their ***** in their pants, but that doesn't mean they're equally prone to turning over the till.

As demonstrated in "Brazil" the government is quite capable of getting Buttle and Tuttle confused with each other and then failing to accept the consequences of the actions that have been taken.
May 27, 2012. 9:40 AMLaserDave says:
The information contained in these "chips" is a factory-programmed string of characters only. Those characters are referenced to a lookup table to indicate what the code translates to. These types of passive electronic tags are far more basic than most people think - they are produced by the billions.

There is NO WAY these can hold your personal information - once they leave the factory they are finished - they spit up their codes only, they cannot take information in. One-way communication.

Answers to your proposals -

The tags require medium frequency waves to operate the chip inside it, the tape demagnetisers Radio Yack used to sell ran at the North American line frequency of 60Hz.

RFID patches are not sewn in, they are stuck on since the piercing of the metallic antenna would either reduce its effectiveness or kill it entirely.

Stores would NEVER be able to gain information like your criminal history, personal finance info and CERTAINLY NOT your race!!! I'm very curious about your reasoning for the race issue. I'm hoping you are joking about the loudspeaker part. This is all impossible because of privacy laws**.

The shopkeep story is pure fantasy, even if personal information *was* on these devices (which it isn't), there would be no way someone could directly access your financial wealth - nor would it be reasonable to assume that such information would secure enough money from a single source, off a single person, to promise a shopkeep a better life back "in his home country". There's the race thing again(!)

Now - there has been a lot of talk and "leaked" information (that I personally believe) that we will be soon on our way to a cashless society, where everything we do will be tied to the information contained in a non-removable implant that DOES contain all of our personal information, including debit card functionality. Yes, I believe that the government (and other unnamed entities) have the perverted and sick capability of using this technology as a means to enslave - absolutely. But those days are not here yet, and it won't be for quite a while - especially now that such plans are out into the sunlight where everyone can see them. The "undesirable and evil entities" we are all aware of NEVER counted on the internet to be the information exchange it has become.

Knowledge is POWER - and we MUST guarantee that NOTHING stands in the way of free information exchange, and we MUST ensure that we ABSOLUTELY preserve this freedom, NO GOVERNMENT INTERVENTION OR CENSORSHIP of any kind should be permitted. Several bills have been
recently introduced under the ridiculously-thin guise of "copyright protection" and to "fight piracy", while trying to sell it with the over-used "for the safety of your children" buzz-phrase that people are finally waking up to. Paid-off media lays the groundwork of making piracy and copyright protection such a hot topic by grossly exaggerating its impact on Hollywood - but in reality the percentage is in the single-digits - it is NOT a problem, it's a lame excuse to limit online content. Naturally, it may begin with only a very, very small portion that everyone could agree to - but once that ball starts rolling, it will pick up speed VERY quickly.

The only way we can prevent our private information from being available to just anyone is by SAFEGUARDING THE INTERNET. It's our LAST line of defense against being enslaved. (I'm not exaggerating) Information spreads from one end of the country to the other in mere minutes, we all need to watch out for one another and have his/her backs. There is going to be a massive SHOWDOWN coming, and I know everyone's instinct can feel it coming. Think about that.

Peace!!

P.S. I apologise for the "rant", but it seemed a reasonable forum to educate slightly as it dealt with privacy theft, the direction it is headed, and what we can do to limit the damage. Also, I don't want to debate this publicly (you may send me a message if you like), so if you don't agree, just ignore it - there is TONS of information out there that DOES agree.

As final comment to make a clarification -

The sticker-type such as pictured above contains no chip, it is just an induction coil that alerts the reader that it's still alive - going through a cashier's lane with a deactivation pad overloads the antenna and blows a fuse so the security system sees it as being "dead"

My comments above were about the types of these similar stickers, and other types of plastic devices that are used, that transmit their codes by activation via cashier's reader and security systems.

More advanced RFIDs such as those in credit cards, can contain a simple code to verify that the information on the magstripe is valid, or they can spit up larger volumes of encrypted information. Passports have a larger amount of personal information that is also highly-encrypted. They are capable of both read and write operations, but do not contain financial details.

At the moment, most RFIDs are basic and provide a simple code (like access control) to be referenced to a lookup table, unless they are used in important documentation instruments.
May 28, 2012. 7:18 AMTreknology says:
There are already people casually walking past someone whilst 'innocently' carry a netbook, and then coming back to their 'victim' and showing all the personal information that was read from RFID enabled credit cards or passports.

After seeing these on YouTube I contacted my bank, supplied them with a variety of URLs, and stated that under no circumstances would I allow my account to be accessed by an RFID enabled device.

I have read on a site that if you keep your biometric passport next to a mobile phone in a purse for example it can erase the information on the RFID chip or even damage/disable it. I have stored my e-passport a couple of times near my mobile phone. I am planning to visit the US in the near future and now I am really concerned. Will my passport chip work properly?
Thx in advance for your answers.

How about this super easy method:
You will needs:
-Electromagnet
DO NOT TRY W/ PACEMAKER. BAD IDEA.
Lets see...
The electromagnet generates a magnetic field that become induced (like a transformer) into the RFID chip, frying it. Yum! Fried RFID...

Does the magnetic field have to be on in it or can it be inchs away from the frid. Thanks OZ
Apr 9, 2012. 8:39 AMwaterlubber says:
depends on the depth of chip and strength of magnet.
Mar 19, 2012. 12:09 PMpuremagix says:
Some of you have been very close to the solution. What you must remember is that this ID chip utilizes a radio signal to power the ID chip. The antenna is nothing more than a coil of wire, which in this case is used to generate an electrical current to power the chip. Like any antenna utilizing and incoming signal to power hardware, it has limitations on how much current it can carry.

Strong electrical fields are capable of overloading the circuits within the chip, causing burnouts. That's why these things are limited on the distance they can be picked up. No matter how they build them later, there are always limitation on power handling capabilities. By using a signal generator and a transmitter, you can determine the frequency of the chip, and by increasing the output of the signal, you can burn out the chip.

Once you think you have defeated the chip. simply reduce the power and monitor the chip to see if it repowers up after reducing the output current. If it doesn't you're home free.

Anything electronic can be easily disabled with an old-fashioned device used by vinyl record aficionados, the Zerostat 3 Anti-Static Pistol by Milty. Records got dust in the grooves. When you pulled the trigger of this little pistol like device it compressed a piezoelectric crystal to emit a whopping powerful electric spark. Aimed at any non-groove part of the record, the whole vinyl was negatively charged so that any dust in the grooves would pop out instantly. No dust in the grooves meant the needle did not damage the record from abrasive buildup.



Aimed at a fingertip it hurt like anything. An electronic component so treated curls up it's pins and just dies as if hit by lightning...which, effectively, it has been.

Any device to overload the chip is a bad idea. You could get burned. Use a sterilized very sharp knife, preferably wielded by a doctor. Intramuscular would definitely require a procedure from a doctor or Vet. Aliens put one in me and I cut it out! J.K. Then microwave that sucker and watch the sparks fly!

My suggestion is using a Xenon flash gun from a camera. Get the glass tube as close to the "grain of rice" without electrocuting the patient and fire it several times. The random electrons emitted with the light flash should distress the silicon components of the RFID.

Remember that an EM Pulse is erroneously named. It is actually a Charged Particle Pulse. Those confused electrons and protons can overload the PN junctions in semiconductors and render them inoperative.
May 27, 2012. 12:45 PMcaptnkrunch says:
where did you learn that EMP are particles?
May 28, 2012. 6:52 AMTreknology says:
Deduction.

Alpha Radiation is made up of 'naked' Hydrogen and Helium Neuclei.
Beta Radiation is made up free-flowing electrons in search of a Nucleus.

BOTH of which are Charged Particles.

Read up on the reaction that occurs in the PN junctions of semi-conductors. If it were truly an EM pulse, then you would not be able to place a transistor anywhere near an inductor.
May 28, 2012. 6:58 AMcaptnkrunch says:
Ahhh. so from your understanding of the operation of PN junctions, you deduced that EMP is formed from charged particles. So if I can produce an EMP from an inductor and a capacitor you would deduce that they are radioactive?
May 28, 2012. 10:05 AMTreknology says:
That is a self-defeating rhetorical question. If that were the case, then my last sentence would have long been proven wrong through experience.

The fact that transistors can co-exist with inductors at ridiculously high frequencies in items such as switch mode power supplies demonstrates that the EM Pulse that can be generated by a collapsing inductor field is NOT ionizing radiation, although some of those frequencies, if too close to the resonance of an organic circuit, can lead to flesh damage, just as microwaves can do.

The classic "EM Pulse" that occurs in relation to fission detonation is the mass distribution of uncontrollable charged particles. The Wikipedia article on EMP is very informative even if the authors do not agree on particles vs magnetic fields. But pay close attention to the goings on inside the semi-conductor when exposed to this radiation.
May 28, 2012. 7:19 PMcaptnkrunch says:
Gee, I don't feel defeated at all. In fact, I think we're making good progress ... now that we agree that there is at least one kind of EMP which is completely unrelated to charged particles. Beside the fact that this discussion, when it began, had nothing to do with ionizing radiation, and still doesn't but you don't know that yet.

Now let's turn our attention to the charged particle theory of EMP. Let's suppose that a fission weapon comprising 22Kg of plutonium is detonated 100 miles away ... in the atmosphere say. What is the particle flux density through one square centimeter perpendicular to the blast assuming a spherical blast, all of the fissile material participates and produces 10 (charged) fragments for each atom of fuel? How does this flux differ from normal cosmic ray flux at sea level? How does this flux differ from that normally experienced in SpaceLab?
May 29, 2012. 6:38 AMTreknology says:
A mock-up of your proposed experiment was performed which yielded zero results, as the measuring equipment was completely vaporized. The observer is expected to survive for maybe another 24 hours. Also, if the premise is wrong (which is what we are arguing), the maths will prove nothing. If you have seen the graphic sequence from Hitch Hikers' Guide to the Galaxy involving the Babelfish and the equations that prove Black = White, the maths is correct, but the premise used was wrong. RGB is additive. CMY is subtractive. As an aside, this also means that if eInk ever goes color it will use the CMYK method.

As stated previously if it were purely magnetic fields that caused the damage then no transistor would survive in the vicinity of high-power inductors inside a switch mode power supply, unless that poor transistor is suddenly spiked by back voltage. I shan't introduce ElectroMotive Force, lest we end up with confusion over which acronym means what.

Are you reading this on a "classic" TFT LCD monitor lit with CCFL? As the thin-film-transistors on the LCD panel are so extremely delicate, have you or anyone else ever observed discoloration because the inverter coils (EMF) are affecting the TFTs?

RFID is several magnitudes more sensitive because it is powered by that field, overloading the antenna with EMF or the circuitry with CPP should be very easy. The firing of s Xenon tube scatters a great deal more than just visible light.

As you are only wishing to split hairs, I see no point in maintaining this argument which is verging on off-topic.

Dec 8, 2011. 3:59 PMlanceearlhaines says:
you are wrong about EM pulse.
Photons (electromagnetic radiation) a.k.a. light is what is emitted, not charged particles. They excite the electrons in electronics to the point where they escape the metal and the metal becomes so hot from the rapidly moving electrons that it melts and burns whatever is touching it.

Nuclear decay , fusion, or fission produce nuclear radiation in the form of charged particles. Some is ionizing radiation. Our earths magnetic field deflects these coming from our sun making life possible. Some charged particles "fall into" the poles giving us aurora borealis and aurora australis. When the charged particles strike the gases in the atmosphere they excite them and they glow much as a neon light does.

The point to a EMP is to strategically knock out electronic devices minimizing casualties. otherwise just use an A Bomb you get both EMP and nuclear charged particle radiation.
Feb 2, 2012. 1:48 AMTreknology says:
If a Xenon tube fired with 100% efficiency, there would be no escaping electrons. Just like a CRT, there are plenty of wild electrons escaping into the environment.

My suggestion is relying on the "super-sensitivity" of RFID chips. They rely on an induced current to commence operation, so a good whack about the electronic antenna should be pretty painful.

The alternative of modifying a microwave oven to attack that part of the body infested with a chip is extreme, haphazard and could do long term damage.

If these chips are to be embedded in the back of the hand, I see chain-mesh gloves suddenly becoming fashionable.
