Modified maximum reading range of passive rfid to 1 meter as per http://www.rafsec.com/rfidsystems.pdf

just had a look at rfidbuzz.com and found that it isn't at all so 360° as it would have to be to qualify to be mentioned as such. Not as it comes across now. These "360° views" (as the article had it before now) are not nearly (equally) "from privacy and industry backgrounds" (as the wording would make expect) but in fact largely industry based (and biased) and few are even just about fairly critical of RFID problem potential. Well, what should one expect when the site's name is RFIDbuzz, compare the descriptive marketing term of buzzwords... Think this justifies adjusting the link comment just a bit. - 00:58, 19 Mar 2004 62.180.204.140

Had another look at the other links and found out most of them are industry not openly saying it. Adjusted the comments to be fair (i.e. reflective of who's talking on those lines). If privacy organizations are identified as such, so should industry sources. Does seem to me that somebody passed by editing the page who is simply a less conspicuous sort of a link spammer. (Didn't remove the links, though, not playing as unfair as I don't think that's professional - although I fear some less conscientious individuals will just maliciously ROTFL about it.)

Reviewed versions: So 13:27, 23 Feb 2004 193.113.48.7 added those spam links on RFIDbuzz.com claiming they were a 360° (read unbiased) information clearinghouse. Sure they seem to be a clearinghouse, but clearingly;-) in a biased (industry) interest. While there's nothing wrong (well, maybe) with interest, there sure is with mislabeling it, whether maliciously or being unprofessionally blindfolded.

What is the distance a passive RFID tag can be read? And how big is such a tag? What size is an active tag? Guaka 18:08, 1 Apr 2004 (UTC)

Altered the range on UHF, Japan uses 950-956. Also removed a funny link to a Spanish site that seemed to have nothing to do with the topic



"If a tagged item is paid for by credit card or in conjunction with use of a loyalty card, then it would be possible to tie the unique ID of that item to the identity of the purchaser" This can be done with traditional UPC labels too- is this really relevant to this article? This is nothing new that comes with a switch over to using RFID tags from UPCs.

No, it can't be done with traditional UPC labels - they do not have globally unique ID numbers, and do not have room to add them. They only identify the product type. Thus your identity can be linked to having purchased a particular type of product, but the specific item is not linked back to you. With RFID of the EPCGlobal flavour, every individual item (above a value of about a dollar) would be personally linked to you. This is an "enabler" feature that synergises with other RFID features that barcodes don't have (inability for the owner to remove or disable the tag, plus ability of unauthorised persons to remotely read it) to create security and privacy risks that simply don't exist for barcodes.

From the article:

The first known device may have been invented by Leon Theremin, as an espionage tool for the Russian Government, in 1945.
Perhaps the first work exploring RFID .... reflected-power communication ...

This stuff about reflected power communication and reflected power bugs is very interesting, but it seems to me that it isn't really about RFID. For a start, until very recently the overwhelming majority of RFID devices were active transmitters and many still are; secondly the essential feature of RFID is storage and transmission of data, especially identity data - a feature not related to these examples. We probably should have an article on reflected energy communication/passive transmitters, link to it from here, and include these two comments. But these comments are not particularly relevant to RFID per se. (I will shortly start a stub for this unless someone beats me to it, but I have an appointment at the moment.) As for the actual history of RFID, I'm guessing it starts with IFF systems, but that's speculation. We can certainly throw in some dates for more recent developments such as Auto-ID consortium, EPCGlobal and so on. Securiger 07:51, 9 Sep 2004 (UTC)

From the article: Also, to deter identity thieves one would simply need to wrap ones driver's license in aluminium foil.

Does anyone have good links to confirm (or deny) this claim, which I've noticed is sometimes in dispute? (The 2 external links after this sentence seem (somewhat misleadingly) to be about the general issue of RFID in driver's licenses, rather than specifically about using foil or other means to counter the RFID.)

Car key cloning?

From: Graduate Cryptographers Unlock Code of 'Thiefproof' Car Key (http://www.nytimes.com/2005/01/29/national/29key.html):

Mr. Sabetti of Texas Instruments argues that grabbing the code from a key would be very difficult, because the chips have a very short broadcast range. The greatest distance that his company's engineers have managed in the laboratory is 12 inches, and then only with large antennas that require a power source.
Dr. Rubin acknowledged that his team had been able to read the keys just a few inches from a reader, but said many situations could put an attacker and a target in close proximity, including crowded elevators.

Can't they use a modified high-power reader and a good antenna? Can't they put two key readers in a door frame or the side walls of an escalator? Anyway, I think tin foil is a clumsy solution. I'll put a switch button on the key. Only when you press it, the key works like a transponder. -- Toytoy 18:04, Jan 29, 2005 (UTC)

electronic details

i'd love to know more about the electronics involved. i'll look it up elsewhere and contribute if i figure it out. - Omegatron 19:52, Feb 3, 2005 (UTC)

History of RFID tags

Theremin's bug and RFID are not the same thing at all, besides the fact that they are both passive radio devices that transmit information. I propose a new article like Passive radio transponders to cover the general principles and mention these two examples, as well as others that exist. This will also provide a place to move stuff like tracking devices and electronic money that aren't really RF identification. - Omegatron 23:03, May 1, 2005 (UTC)

Removed all the linkspam crap. Probably more should be removed. Move back individual links if they are truly relevant. (Hint: They aren't.) - Omegatron 17:43, May 6, 2005 (UTC)

rfid

look at us in the tech age right now, one day we can be able to track anthing that exists on this world!

Movie references

When I saw the third James Bond film Goldfinger, do RFIDs exist back in the 60's? There was a device which is similar to the little metal wafer that James Bond tucked into the heel of his shoe.

Several RFID factoids

Latest comment: 20 years ago1 comment1 person in discussion

In the recent DefCon, someone demonstrated the ability to read (presumably passive) RFID that should be read at 4-5 inches at 69 feet. http://blogs.pcworld.com/staffblog/archives/000798.html http://www.makezine.com/blog/archive/2005/07/_defcon_rfid_wo.html

Toronto's 407 Expressway has a transponder that will charge the car's owner based on mileage. At least this device perform similarly to the RFID. --Calyth 17:09, 10 August 2005 (UTC)Reply

RFID equipment vendors (External links)

Removed the equipment vendors external links section in its entirety. I feel it violoated WP:NOT on several counts. If anybody thinks I was wrong. feel free to drop a note on my talk page. --GraemeL (talk) 12:47, 3 September 2005 (UTC)Reply

RFID history

Latest comment: 19 years ago1 comment1 person in discussion

It's true that Theremin used reflective radio waves, but I wouldn't call that RFID either. IFF protocols are an interrogator/responder system that works over radio waves, but I don't know that in its original incarnation in the 1940s it was automatic? Anyway, the first patent for a generic passive transponder that communicates over radio, light, or acoustical waves was issued to Mario Cardullo in 1973.

UHF

Doesn't EPCglobal's EPC Gen 2 standard define a global UHF standard?

added to == Passports ==

Added som stuff to the passport section about the US issuing passports with RFID tags from October 2006 and about the Norwegian Passport authority.

changes to types of RFID tags

I removed the sentence Analysts from independent research companies Gartner and Forrester Research agreed that a price less than $0.10 (production volume of one billion units) is achievable in 6–8 years, thus limiting near-term prospects for widespread adoption of passive RFID; however, the high demand for the tags from Wal-Mart, DoD, METRO, etc., has created a market gradient to support these prices. because it made no sense in conjunction with Today, as universal RFID tagging of individual products become commercially viable at very large volumes, the lowest cost tags available on the market are as low as 7.2 cents eachin volumes of 10 million units or more.. Maybe the Gartner sentence should have the cost as one cent instead of ten? I couldn't find the source for the Gartner claim so I removed it for now.
