What is Digg?67 Comments
- Hypersapien, on 10/12/2007, -0/+4Great. Now all we need is a simple-to-make RFID detector. You want to fry the RFID tag in the new jacket that you just bought, but it is hidden somewhere inside the fabric and stiching. We need something to wave over the jacket and have a little light go on when it finds the tag, then we use the zapper until the detector stops lighting up and we are sure that we got the little bugger.
- NervousDuck, on 10/12/2007, -0/+3Well, people are confused about RFID. There are active RFID tags that actively transmit their information. They would be battery powered, and not designed to be used forever anyway, unless solar powered or something crazy like that. What an RFID tag on a PRODUCT would consist of is much like the SensorMatic security tags already in place on many products. It's just a wire coil that, when excited by a transmitter, responds with a unique signal. On these devices, there is no capacitor to blow, just rip the tag off of the box if you'd like. What will most likely happen with RFID product tags, is they will be included with a UPC, with the RFID tag just under your barcode. Unless you embed these tags inside of products, and they can't be easily removed, the magic of walking through an RFID transmitter, and checking out in seconds isn't realistic, because it's all too easy to just rip tags off and get away with purchases.
- jrsmith, on 10/12/2007, -0/+2I work at wal-mart and the way they are using it is to track merchandise going out of the warehouse and into the store... It's not on every single item, only in the case that it comes in.. There are sensors at every door leading in and out of the building EXCEPT for the front door because their intent is not to use it to catch shoplifters, rather to track where the case of merchandise was last "sensed" in order to help us keep track of merchandise within the building. I have had a some time to play with the RFID tags that are taped or glued to the inside of the cases and just simply bending the tag in half (not creasing, just gently folding) will make it un-detectable and also surrounding it with metal (such as the carts we use to stock) also makes it un-detectable. There is no need for a device that disables the tags. I can see people's confusion because nobody is really talking about what they are doing with RFID right now and it is possible that they could be used to track people but I don't see it happening..
- NervousDuck, on 10/12/2007, -0/+2If you want to listen to a good overview of how Zebra, a lable printing company, has worked with RFID. It covers the history of the technology, how it works, and how it will be used in the future.
http://www.zebra.com/id/zebra/na/en/documentlibrary/webinars/radio_frequency_identification.File.tmp/RFID_webinar.swf - Everman, on 10/12/2007, -0/+2Obviously RFID manufacturers will need to figure out how to defeat something like this. Similarly any chip on-board a satellite needs to be "hardened", be able to take the abuse of space such as radiation and extreme temperatures. How soon will we have hardend RFID tags?
- forgiste, on 10/12/2007, -0/+2Im sure that they would put the RFID tags inside the packaging to make it harder to rip off.
- bash, on 10/12/2007, -0/+2RFID is simply scary. its bad enough getting people (senators, RFID sellers, etc.) saying "it can't be read except within a distance of 10 feet" and meanwhile defcon guys are reading it from 60+ feet.
- jdong, on 10/12/2007, -0/+2Scariest thing, I've built one of these before, almost exactly the same way (disposable flash camera capacitor used with a nice, professionally-wound electromagnet for physics lab demos), and when discharged relatively near to any kind of electronics (walking past, for example), it's capable of dealing a pretty damaging blow, if not rendering the whole device useless.
- PlusTheBear, on 04/25/2009, -0/+1Thank you. Seriosuly.
- PlusTheBear, on 04/25/2009, -0/+1These people must be paid for saying these things. It's the only thing that will let me sleep at night.
- johnpombrio, on 10/12/2007, -0/+1 OK, once again, R FIDs are nothing more than barcodes that can be scanned at one foot instead of 4 inches.They are already being used in tremendous amounts in the US for the last ten years. The OUTPUT of an R Fid tag is a 15 digit number. OH MY GOD! It is giving away my entire life history! I mean all you have to do is to READ this number and learn... what? The only thing this number is good for is located on the database of the retailer. So you go out of the store with a passive R Fid tag that is still able to respond. The sneaky terrorist reads your number and learns... nothing. Well, he could crack into the retailer's database and learn what the number means. Campell's cream of chicken soup. Now that is scary! Wait, since the terrorist is already into the cracked database, would he not want to read your credit card number or home address instead? Hell yes, he would. But that is why companies protect their databases, I mean like REALLY protect their databases. So it is the DATABASE NOT the R FID that is your vunerable spot.
As for the passport, again the output of an R FID tag is only a number, no personal information AT ALL is on the tag. The real information is stored on the government's computer. Is the database safe? If it is, then there is NOTHING that can be learned for your R FID chipped passport.
Finally, as far as the government "tracking you" with short range R Fid's, give me a break. The FBI would have to get up close to you, read the campell's soup can R Fid, crack the supermarkets database and find out all of the customers in the store that bought the soup (if you use their express savings card that is) and track down each one of them. Likely? Hell, why don't they just read your CELL PHONE location. I mean that number is published and by law needs to tell where it is. So get rid of your cell phone!
BTW, if you have a toll booth R Fid device, the government is read that right now (but only if the toll authorities open their database of course). My God, I have to shield my EZPASS transponder right now! The government will know that I went through the Springfield toll booth yesterday! - solace9, on 10/12/2007, -0/+1So, what...then a nation that has all it's people get rfids and then gets into war with a nuclear nation will be in trouble when the first nuke is detonated midair to create an emp blast when the the damaged capacitor creates a sore? Plausible? Probable?
- mikeyG9x, on 10/12/2007, -0/+1Born, raised, and bred in the good old USA.
- nogami, on 10/12/2007, -0/+1You could probably have an interesting time with these if the US department of somethingorother goes ahead with their plan to RFID all passports. Apparently if the RFID chip in the passport is dead, your passport is also invalid and you ain't going anywhere out of (or back into) the country...
You could play havoc with people's travel plans by cooking the RFID tags in passports around airports and such...
Of course, the whole RFID-in-a-passport idea is a really dumbass thing in the first place. If they were smart (which isn't likely), they'd just something akin to a GSM SIM card embedded in the passport. The problem being that their plans are likely to eventually track every person and their path as they move through airports and across border crossings. (ya, they say they'll have the tinfoil "wallets" to protect reading from a distance, but anyone want to bet how long THAT will last?).
N. - Hypersapien, on 10/12/2007, -0/+1I have no problem with an RFID tag being used like a UPC symbol, the problem is when they use it as a serial number.
- DCstewieG, on 10/12/2007, -0/+1Am I the only one who thought from the headline that the Nintendo Zapper gun was going to be re-released using RFID for targetting? (if that's even remotely possible anyway)
- Tiak, on 10/12/2007, -0/+1If you're within range for the EMP to destroy an extremely small unpowered electronic device, you've got other things to worry about.
- Tiak, on 10/12/2007, -1/+2... You realize that's the equivelant comment of "it would be nice to smack someone in the face with an active tesla coil" right?... Or how about "It would be fun to beat a puppy"... Hurting people != cool
- surfing, on 10/12/2007, -2/+3This would be fun to use on folks that have rfid implants.
- deathpasser, on 10/12/2007, -0/+1"R Fids are about as dangerous as a barcode." johnpombrio
Barcodes aren't dangerous at all, thats stupid. RFID tags actually allow for unique potential tracking of individuals, you can't do that with bar codes. Its a matter of privacy, if privacy is unimportent for you, two thumbs up, but for those of us who do give a *****, thats who oppose RFID tags becoming more and more standardized in products. You should be allowed to risk your privacy all you want, but for those who want to maintain theirs, they should be allowed that similarily. - PlusTheBear, on 04/25/2009, -0/+1Later material possessions. And creepy guy hanging over me.
- PlusTheBear, on 04/25/2009, -0/+1It's the principle. The word is called 'principle'. Pick up a dictionary.
Oh and they'd be tracking ALL OF US. That's numerically different than YOU AND YOU ALONE. - multifaceted, on 10/12/2007, -0/+1"RFID Freaks - the new tinfoil hat crowd."
RFID can really be used to track you.
Tinfoil hat people are afraid of Aliens."
Okay tin foil = aliens
duct tape = RFID (that wallet) - kolop1, on 10/12/2007, -0/+1"RFID Freaks - the new tinfoil hat crowd."
RFID can really be used to track you.
Tinfoil hat people are afraid of Aliens.
RFID is a fact. Aliens are unproven. Don't compare the two. - tidal, on 10/12/2007, -0/+1will this disable the rfid chips oming to US passports?
http://www.digg.com/security/U.S._passports_to_get_RFID_chips
totally unnecessary in passports - QuiescentWonder, on 10/12/2007, -1/+2No digg.
If you morons would read a little before assuming you can cause mass chaos with one of these things Digg would be a better place. These only destroy ACTIVE RFID TAGS. Not the other kind, not the kind that would be in passports and the kind that will eventually replace bar codes. Besides, this is the equivalent of ripping UPC codes off of products, and we have all been capable of doing that for a long time haven't we?
"So, what...then a nation that has all it's people get rfids and then gets into war with a nuclear nation will be in trouble when the first nuke is detonated midair to create an emp blast when the the damaged capacitor creates a sore? Plausible? Probable?"
I usually wouldn't respond to this but this story is just so ridiculous. So... besides it not destroying anything but the ACTIVE version of RFID... how in the hell would the registers ring up bar codes anyway? Everything is ruined, not just RFID tags. Amidst all of that, you seem to have forgotten that this proposal is not even close to probable, plausable? Maybe with a lot of time and effort and money.
Those people who have RFID tags embedded in them? Those aren't active, so it won't work here.
"Obviously RFID manufacturers will need to figure out how to defeat something like this. Similarly any chip on-board a satellite needs to be "hardened", be able to take the abuse of space such as radiation and extreme temperatures. How soon will we have hardend RFID tags?"
They don't need to be hardend, because this device will pretty much ruin any electronic equipment if you get close to it, but OH! Look! Doesn't ruin anything buy ACTIVE RFID tags.
"Say goodbye to the chip in your credit card, PDA, digital wrist watch and that guy next to you with a pacemaker."
Exactly
"A high powered blast of EM waves is likely to be very dangerous for the user. There's a reason why microwave doors are so carefully designed to prevent any EM waves from escaping: it's dangerous. More like a cancer generator than and RFID deactivator."
Uhh, no. These aren't the same thing. Microwaves emit microwaves (hence the name), EM stands for electromagnetic. Not even close; no cancer.
"Barcodes aren't dangerous at all, thats stupid. RFID tags actually allow for unique potential tracking of individuals, you can't do that with bar codes. Its a matter of privacy, if privacy is unimportent for you, two thumbs up, but for those of us who do give a *****, thats who oppose RFID tags becoming more and more standardized in products. You should be allowed to risk your privacy all you want, but for those who want to maintain theirs, they should be allowed that similarily."
I'll ignore the fact that it's not possible and ask why WalMart would want to know which door you walked out of the exit... or where you were walking around the store? Marketing maybe, but who gives a *****, it doesn't invade your privacy as it would be illegal for them to track specifically you, it would be anonymous. RFID tags being used as bar codes can't be tied to you unless you use a credit card to buy them. Besides that, you care that WalMart would be tracking your movement around their store? You aren't involved in this, what are security cameras? Security cameras track everyone in the store at all times and it's recorded. Once again, these aren't active RFID tags so once you leave the proximity of the reader, they have no idea where it is.
"I may not be doing anything illegal today, but what happens when the laws change and what I did last week becomes illegal? Databases can be searched. I am not doing anything wrong, so the government has NO need to track me."
Not doing anything wrong buy destroying a store's property? I think that's a bit illegal. Even if it isn't illegal, you can't be arrested for rearranging all the items on a store's shelves, but they sure will get pissed and throw you out and tell you not to come back if you do it too much. - swarve, on 10/12/2007, -0/+1Anyone got a new RFID passport?
My new Aussie passport comes with one in the center page, im thinking of zapping it as i dont want my info read by anyone. - cshepherd76, on 10/12/2007, -0/+1Destroy the spychips

I am not doing anything wrong, so the government has NO need to track me. - dr_benway, on 10/12/2007, -0/+1I'm sure, almost positive, there was a perfectly good reason why you provided a link to a blog entry instead of the link to the original design article it references: https://events.ccc.de/congress/2005/wiki/RFID-Zapper(EN)
- bernardroth, on 10/12/2007, -0/+1In the US RFID is big business. Look at the GAO reports to see that the military spent $7mil in 2005 and a projected $437mil for 2006-2011 just for RFID.
Do a search for "rfid passport" here: http://www.gao.gov/index.html and you will find reports that they do not have solutions to the major privacy issues yet.
My big problem with putting rfid in passports is that it makes it easier for them to do things without asking you. Right now we have to show ID just to get on a plane. We have laws that are state secrets for national security reasons. Without an open system there is no accountability. There is no reason to fix a problem if no one knows about it.
A good rfid workbook: http://www.zapped-it.net/devices.html - repellent, on 10/12/2007, -0/+1Are you thinking what I'm thinking?
http://www.electric-clothing.com/chipped.html - asdfasdf, on 10/12/2007, -0/+1This won't last much longer. Soon they will make products that get disabled if the RFID tag is zapped. So you would have to do some sort of modding/hacking to get the product to work without the RFID component enabled.

Next on digg: "How to make bombs out of ordinary household chemicals" and "How to defeat security measures at our nation's airports" - deathpasser, on 10/12/2007, -0/+0"Great.

That there is heavenly innovation, I would start working on it if I knew anything about electronics (well more than the simple AND, OR, NOR gates etc. - jumjum, on 10/12/2007, -0/+0There could be alot of money in an RFID reader/zapper combo device: read the tag for the dotted data, zap it, then see if it has changed as much as it can. Some chips are engraved with their serial numbers at the factory and can't be erased, akin to a music CD that you buy, but the other prefix decimal data (the manufacturer and product category) can at least be erased.
- zelig, on 10/12/2007, -0/+0Great accessory to the magnet arthritis bracelet.
- Takumi, on 10/12/2007, -0/+0Hmm and what about the guy that inserted an RFID into his hand, that would be painful

I had somehow never thought of that, that would be awesome and in certain circumstances they could be embedded inside those ink anti theft tags although there would be the whole problem of removing the ink tag ( ie you couldn't just pay by walking out the door ). And yes I don't see any way of disableing a passive RFID tag other than just shielding it.

Well, if you have nothing to hide?.....This can be used to justify almost anything right?
Count me in for the zap squad. - meangene, on 10/12/2007, -0/+0I, for one, welcome our new RFID overlords.

Duh. - inactive, on 10/12/2007, -0/+0Submit a story on a 2-in-1 RFID detector AND zapper and then I'll digg it. What good is a zapper if you don't know where the tag is?
- Zonkzor, on 10/12/2007, -3/+2I would love to see this built into a easy to carry device like a wrist watch. It will be interesting to see what countermeasures are thought up to combat this. Eventually stores will completely switch over to RFID as a primary way to ring up items at the check out and do inventory. They sure wouldn't be happy with some guy silently walking down the isle frying everything.
This is going to be a fun cat and mouse game to watch :-)
