In this step I will describe a few ways to permanently disable or kill an RFID chip. Most products that you own that contain RFID tags belong to you, so you have the right to destroy them; however, tampering with a US passport is a federal offense. Luckily there are ways to kill an RFID tag without leaving any evidence, so as long as you are careful, it would be pretty hard to prove that you did anything illegal.



-The easiest way to kill an RFID, and be sure that it is dead, is to throw it in the microwave for 5 seconds. Doing this will literally melt the chip and antenna making it impossible for the chip to ever be read again. Unfortunately this method has a certain fire risk associated with it. Killing an RFID chip this way will also leave visible evidence that it has been tampered with, making it an unsuitable method for killing the RFID tag in passports. Doing this to a credit card will probably also screw with the magnetic strip on the back making it un-swipeable.

-The second, slightly more convert and less damaging, way to kill an RFID tag is by piercing the chip with a knife or other sharp object. This can only be done if you know exactly where the chip is located within the tag. This method also leaves visible evidence of intentional damage done to the chip, so it is unsuitable for passports.

-The third method is cutting the antenna very close to the chip. By doing this the chip will have no way of receiving electricity, or transmitting its signal back to the reader. This technique also leaves minimal signs of damage, so it would probably not be a good idea to use this on a passport.

-The last (and most covert) method for destroying a RFID tag is to hit it with a hammer. Just pick up any ordinary hammer and give the chip a few swift hard whacks. This will destroy the chip, and leave no evidence that the tag has been tampered with. This method is suitable for destroying the tags in passports, because there will be no proof that you intentionally destroyed the chip.

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.

How would you kill a rfid chip that is injected under the skin? They put these in crazies and people with Alzheimers desease. Got any idea? Magnets maybe?
Sep 11, 2011. 11:56 PMkgee says:
can't you use a small controlled emp?

or can't you use a RFID writer? i seen somethig on this site a while agot about that.

Maybe its a good idea to able to track pop pop when he wanders off. And the crazies when they are on the loose.

I think I would hit them with the hammer method. The micro wave would be to cruel. Its a good question and would like to know myself.

yea. just wac a hobo with a hammer!!!

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.

sOUNDS WORTH A TRY WHEN THE TIME COMES.
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.
Feb 5, 2012. 12:27 AMlanceearlhaines says:
Sure wild electrons are escaping atoms all the time but without an accelerator and a sufficiently focused beam of high intensity, the ionizing effect of randomly escaped electrons from devices is quite minimal.

Furthermore, Without a significant fluctuation in the surrounding MAGNETIC field an overload current will not be induced in the sensitive RFID chip. Simply hoping escaped electrons from a device designed to create visible light, I would bet my life, is not adequate to fry an RFID. Just think of the thousands of cells and layer of fat not to mention the capsule around the chip that can absorb or deflect the incoming electrons. We are talking billions of atoms in the way.
May 28, 2012. 12:31 AMTreknology says:
RFID tags are meant to be activated by low-power fields. The rapid pulse of a high power nearby SHOULD stress the extra-sensitive components, and if the low power can get through for normal operation, those billions of body cells aren't going to be too worried about trying to deflect a Xenon flash. People can stick their hands in the middle of a carbon arc if they really want to zap things up.

Please name the race that tagged you.
Please also provide Registration and Vehicle type, along with photos of the formerly implanted device.

go have an injection/ blood drawn from there, in the hope the needle pierces the tag at a mental hospital? get sedated there...
Jan 17, 2010. 5:01 PMalmightyally says:
 using a tazer close to where the chip is implanted should fry it, itd hurt like hell though.

you my friend just made my day hahahaha
May 7, 2009. 3:03 PMand7barton says:
If we ever sleepwalk into a compulsory injected microchip society, the answer to this would be to cut the skin and pop the capsule back out as soon as you get home from the "Citizen's Implant Centre". Then you can tape it onto the outside of your arm, and remove it when you choose to.

How about don't accept it in the first place?
