RFID Eraser, how make?

[Nehmo]

RFID tags are becoming more prevalent, and being able to turn them off is becoming more important. You can block the radio transmissions to and from a device simply by covering the device with foil, but disabling the cip is most effective.
A passive RFID device is an antenna attached to an accompanying chip, and physically destroying the chip or disconnecting the antenna works, but it's crude in terms of procedure. I'm looking for a non invasive method. You can see one such non invasive method at store point of sale cash registers. They use a disabling-mat. I suspect the mat is just a coil with some kind of AC going through it.

Once, as a kid, I had a jig saw, the kind that just vibrated the blade up and down. It was done by an electromagnet attached directly to the 120V 60cps line. I think that kind of coil would work to kill an RFID chip. I don't have a magnet like that now. But maybe I could find some other similar device. What kind of electro- thing commonly available has a decent electromagnet inside, something that could be used to zap an RFID tag?

Those mats erase EAS tags, Electronic article surveillance. They're magnetic, and easy to erase.
RFID are passive chips that respond to a radio signal. EMP might destroy it, but getting a big enough pulse to damage it might need to be done in a shielded box.

More likely it just reads the code and removes that item from the stores' inventory so alarms aren't triggered as you leave.


Easiest methods would be a hammer to the chip, or putting it in a microwave, but both could be a bit destructive if it is stuck on an item.


Really high ESD may also work. But the RFID would be designed to withstand a nominal amount and it would take trial and error to figure out what level (>10kV?) may work reliably

 

[nutnspecial]

What rfid's do you want to eliminate?

I heard people microwaving rfids to destroy them. Never tried it.


Hmmm, hold on a sec.. . . .







Well that worked. This is my latest credit card and the first they sent me that was 'smart'.
I think it made a little pop immediately. Now you can see the little circle raised on back side. Wonder how I would test it.
I wonder if they're in our money yet.

If the pretense is for 'privacy', RFID is low on the totem pole when it comes to active or passive tracking and mostly misplaced fear/FUD.

Most RFID is concerned with supply chain tracking and you'll find it at the pallet level for most large retailers. Active RFID is more for asset tracking internal equipment and usually doesn't make it out in the wild.

Aside from physically damaging the device - the only other way is to put lots of energy back into it (ala the microwave method above). But when they are in things like your tires, how exactly are you going to stuff them in the microwave .

You can buy a cheap software defined radio and go about searching for RFID and you'll find it's not that nefarious .

There isn't any smart listing of items in store front alarms. You could take a tag from one store and it will set off the alarm of another store.

That's how this prank works:

I don't know, I don't like the idea of having a tracker (an rfid- that uniquely identifies and can be programmed for different info) that small and then have companies wanting to but them on everything, while people are in the news talking about injecting them under human skin.
Reminds me of the beginning of the 'bourne legacy',
complete with active rfid and drones

Imagine the possibilites. Even cash anonymity could be completely quashed by maintaining a cash rfid system.
I can imagine a society where you need an rfid implant to buy or sell, but I have a big imagination I guess, or I'm just old fashioned.

Also check out 'smart' meters the power companies are starting to use. Not just wireless power usage amounts, apparently they identify and are capable of transmitting what is running and when in each household, from a hairdryer, to a pc, to a light bulb etc.

If you were a multinational conglomerate, wouldn't you love to know how, when, and how much customers used your goods? Enter 'smart' devices. They're smart alright lol.

Yeah, I'm against that idea too. The furthest I would go is a virtual wallet in my phone so I have a choice.

I also don't think it will eliminate cash money. Too many drug deals going on for that to happen. Now, if the war on drugs ended, they might be able to rid us of cash.

Then you shouldn't use a cell phone, the Internet, purchase from large retailers, drive a car, use a debit/credit card, etc. I agree that this urge to track everything/everyone is kinda absurd, but it's so pervasive I could list hundreds of ways that individuals can be tracked/de-anonymized in modern times.

But RFID has little to do with it and this fear of it has made commerce less efficient.

On the flip side:

under human skin.

Doing the same to track lost pets is kinda awesome, right?

complete with active rfid and drones

The DoD already has plenty of ways to actively track 'targets' and RFID is at the bottom of the list (cell phone, IR lasers, FLIR, SAR, ARGUS, good ole' GPS, etc). RFID research [and later the 'smartdust' project from Berkley...which evolved into Zigbee/BluetoothLE/Apple iBeacons] was championed/funded to keep track of military assets when in travel and to avoid things 'falling off the truck' so to speak....

Again, the RFID fear is overblown.

Even cash anonymity could be completely quashed by maintaining a cash rfid system.

Cash is already at least partially de-anonymized. All major banks used cash counters which detect serial numbers and even log pictures of the bills for 'auditing'/'counterfeit protection' which are date stamped and correlated to each tellers daily drawer change. Same with ATMs. And US currency (even lowly $1 bills) are detectible at a distance thanks to magnetic ink (not the mylar strips as once supposed).

Also check out 'smart' meters the power companies are starting to use. Not just wireless power usage amounts, apparently they identify and are capable of transmitting what is running and when in each household, from a hairdryer, to a pc, to a light bulb etc.

My specialty is in Zigbee (the protocol powering 'smart meters') and the tracking of appliances has little to do with the 'smart' part of the meters. Detecting transient power signatures has been around since the 90s at least. A negative public opinion of 'smart meters' just makes moving to 'green' power sources with solar/wind micro-grids nearly impossible.

If you were a multinational conglomerate, wouldn't you love to know how, when, and how much customers used your goods?

As a consumer, wouldn't you also like more knowledge about the supply chain of the stuff you consume? To better target recalls, facilitate recycling, verify authenticity, ease checkout times, etc. People that use Easypass (RFID) aren't exactly wanting to go back to tollbooth operators, etc.

'Privacy is Dead' and has been for a long while. It's now up to us to embrace technology to improve our lives and the environment.

 

[nutnspecial]

Wow, excellent reply. I would not disagree with a word you said. That's too strange that you have first hand experience with smart meter software too!!!!

Hopefully without disagreeing I can say 'slippery slope' and 'downward spiral':

To me the line was crossed in lost years millenia ago, and everything since is just
a 'slide for home'.

There are no happy endings in this life, and technology cannot change this.
In this world, of flawed mankind, tech's negative affects will always outweigh the positive.
No different than our perception of the life of a fly, or a solar system.

I really do try to be an optimist. . . where my realist nature permits .

Seriously no worries here. I don't mind if people want to grid tie everything to a potentially inescapable system (of control). It's actually comforting to know things are moving towards an outcome.
I just don't want history to keep repeating, it gets old.

Rfid in us news https://www.youtube.com/watch?v=IoRXNgCqyyA
On bbc https://www.youtube.com/watch?v=7JPlTEnUO4E

Implantation, just another step towards the irreversable loss of our humanity. Transhumanism, watch out for it. I truly believe there will come possibly 'hybridizations' that could threaten one's very soul.

Think about it, what makes you human, and are you prepared to lose it?

 

[markz]

Why do they stop, when the buzzer goes off when they leave?
I bought a winter coat from walmart that had one of those rfid thingys, and I never bothered to remove it. Buzzer would go off and I would just keep walking, no one ever came running after me, ever. I want to find one that goes off on ever exit alarm. Now that would be fun. I'd even act all suspicious.

Wouldnt those RFID's work to track your ebike?

 

[nutnspecial]

They do have ebike, or other unique identification capability at a distance, but gps is more for tracking lost stuff.

Rfid's are a different beast, they are a 'passive' information storage system, able to be powered and then read from a distance with radio frequency.

 

[markz]

OK Gotcha, so the new chip cards have the tap-n-go, which is RFID, its easy to buy stuff, also easy to steal that info too.
How close do you have to be to read the info from a chip RFID card?
If you have stacks of cards in wallet, then lots of RFID's, so the theif would need a reader under the corded remote machine. No pin no nothing needed.

Im damaging my RFID's on my cards now. And requesting the bank send me non RFID, doubt they care!

 

[nutnspecial]

Funny story, had to go to the county building, and they have new 'smart' coinmeters. I had no change, and it only wanted a smart card lol. The one I fried above didn't work so well . I had completely forgot I did that until that moment, so I had to laugh.
Parked anyway. It was a short visit anyway.

On the distance, I've heard it's mainly dependant on the power of the rf source. Could be from a large distance. But would have to find some sources to cite.

 

[Punx0r]

RFID is used to tracking inventory through a system. Don't be paranoid.

 

[markz]

Theres a county in the USA somewhere, I think its do to with Space or Military, but they have strict rules on RF stuff, no cells, no radios, no phones, no tv etc.
They have a truck roaming around all the time scanning the airwaves.

The government can track down a specific signal pretty easy these days.
Makes you want to get an old bag phone on the AMPS system, if they still have that legacy network still running.

 

[Punx0r]

It's called the National Radio Quiet Zone: http://www.bbc.co.uk/news/magazine-32758042

It's home to an enormous radio telescope for scientific research and an NSA listening post.

 

[markz]

Ut oh, NSA is listening in to our convo's.
Where is their main NSA headquarters building located?
Highly Top Secret Stuff going on there. I hear they got football fields stacked a few stories high of data collection. Just store it away I guess and skim throught it.
They record everything, like Google and Gmail. They might be in kahoots with each other!

 

[Scottydog]

I remember watching a youtube vid on this few years years ago where they modified an old disposable camera.

Awesome hack Scotty! that leads to a whole world of cool hacks on utube I never looked at.

 

[nutnspecial]

So that card I fried only works on non smart readers, even though the 'smart' readers can read old cards. I guess there is still evidence of the radio frequency idendtifier that is linked to the magnetic strip.

Anyway, now lowes is forcing a smart card. (sent one and disabled the old one for "greater protection"). I am considering calling them and raising some sort of stink that I want the old strip card, but likely that will go nowhere. I would tell them to pound sand, but the damn lowes card gives 5% off all store purch and 20$ deliveries. Raugh! This will be how it goes when we are 'forced' to take an implant or whatever the next step of 'progress for our protection' is.

What do you'all think of this logic.
Struck a cord with me on passwords and usernames lol.

The stores are being forced to used them due to their higher security- if they use the old cards the store is liable for fraud, not the credit card company.

 

[nutnspecial]

I thought perhaps the stores had some say, or at least only one major provider's store affiliations are a target presently. If not already widespread, it will be.

It is logical for the card companies to make policy because they cover the fraud.
My attitude remains tho. Also what did u think of the wellsfargo/online password above?

Also, I hate how they call them 'smart' & 'chip' cards. Sure they store data, but they really don't process anything.
Passive radio identifier, with the ability to be read, and maybe be written to?

I don't believe it is admitted there are any rfid's in money, correct? Has anyone felt a stack of the new 100$ bill? There is a little bump in the bill that becomes more noticable against the paper thickness as stacked. Try with at least 10x.
