How to block/kill RFID chips

March 5, 2010 by Infowars Ireland

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.

RFID Chips in Tires and Roadside Monitors
Executive Summary – Tire companies are putting RFID chips in auto tires. This is supposed to be part of the low air pressure in tires warning system. These RFID chips are keyed to the VIN number of the car if the tire is original equipment with the new car. The VIN number of course leads to the registration information. Add in roadside monitors for RFID chips which are already in place in parts of the USA and you have the plot. Of course the government is genuinely concerned that you might be driving around with low tire pressure. It seems there are not enough cars with GPS systems to enable easy tracking of cars.
Wal-Mart is another RFID disaster. If you buy some items it will have an RFID chip embedded inside the item making removal difficult without damaging the item. If you pay by check or credit card this item through the RFID chip can be associated to your identity like by a roadside scanner. Things like New York’s EZ Pass, Florida’s Sun Pass, and California’s Fast Trak are all RFID monitoring systems to collect road revenue.
Blocking RFID Signals – Put your wallet and passport in aluminum carry case to block the signal. There are special wallets and passport cases sold on the Internet now that do a good job of this. Your RFID credit cards should be in the aluminum wallet to block their signal as well.
Disabling RFID Chips – When you buy an item (not a government issued passport or other id which is actually the property of the government that issued it) and they include an RFID tag with the item, the RFID tag is now your property and you can destroy it freely. Here are some ways to kill your RFID chips so they do not commit any further privacy invasion.
1. If you know where the RFID chip is hit it with a hammer hard a few times.
2. If you know where the RFID chip is puncture it with a knife or an ice pick a few times. They do not bleed. Attacks with a pliers or vise grip can also be rewarding.
3. If you can get visual access to the chip, sever its antenna so it can no longer transmit or bounce a signal back.
4. Put the chip in a microwave for five seconds. This will kill the chip but may get a little messy. Not so good for your microwave either so don’t keep doing this in that it could damage your microwave.
5. Possible Solution – Place the RFID in an item on or in a demagnetizer. This may screw it up. Try it in magnetizer and demagnetizer mode.
6. Possible solution is to zap the RFID chip with a strong stun gun or taster several times. This should have some disabling effect.
Disinformation Fun With RFID Chips – Take RFID chips out of items when you can get to them and remove them carefully to keep them functional. You can now place these RFID tags in other items. Be creative. Try to enjoy yourself as much as possible. Do not place them inside of items for sale in stores in that this can disrupt their business. Random items like vehicles in the street can be likely places for RFID transplantation. Imagine the fun, especially with certain kinds of vehicles. Leave a RFID or two inside of busses and taxis in nice places where they are likely to stay for years. Send your RFID chips around the country or continent in trucks.
When traveling to foreign lands bring your inventory of liberated RFID chips, they are not contraband and can be transported. Donate some RFID chips as you see fit always remembering to enjoy yourself and not break any laws. Trade RFID chips with people in other countries. Load your car up with numerous RFID chips. Best if from different countries or at least different regions. Great RFID reader interpretations for sure. Why are you traveling all the time every day?
Make up your mind to have a good time and enjoy yourself. Disinformation is the real weakness with the RFID chips being used other than for what they were intended to be used for.
