Chemical, Printable RFIDs 285
Syre writes "The RFID Journal says that CrossID, an Israeli startup, has developed an RFID system that can be printed using an inkjet printer. The 'nanometric' RFID system uses tiny particles of chemicals with varying degrees of magnetism that resonate when bombarded with electromagnetic waves from a reader. Since the system uses up to 70 different chemicals, each chemical is assigned its own position in a 70-digit binary number. 'Previously, there has been no way to protect paper documents,' says Moshe Glickstein, CrossID cofounder. 'We have created the first firewall for paper documents.' The big advantage is that the tag can be printed on just about anything. 'It's as easy to create as a printed bar code. And we can print in invisible mode for extra security. Printing the tags cost less than 1 cent each.' Their FAQ
says that 'CrossID can be read from quite a long distance'. No word on whether it can be user-disabled..."

That is not very practical in the real world.
Most times one wants to steal a whole bunch at a time.
I am sure we have all read interesting things that
are left sitting in the printer unattended... that might have
value to someone else outside the company doors.
So that seems to be what this system might stop.
One cannot stick 100 pages of information in their
pants, covered by their shirt and just walk out.
At one cent a page, it seems very reasonable to install those
directly into your printer. I want one too. Well as long as it
comes in a normal printer as an added feature. Let the printer
company pay the license fee, and I will buy the special inks.
Profit.

Actually, they say they could print this on all kinds of materials, so it could be sprayed onto products before they are painted, etc.
I kind of doubt you could deactivate them by overloading them, as you can other RFIDs.
This could be a rather invasive and hard to counteract development...

It's just a RF barcode. It lets machines read things a little bit easier. There is nothing very secure about it, especially once it becomes widespread.
The biggest change I forsee is that the cashier at the grociery store - if they still have a job - won't have to touch anything. The conveyor belt will scan all the food as it goes down to the bagger, and probably your RFID Credit Card too.

So if you want to mess with it, all you need to do is add a few drops of glue with (say) 15 of the chemicals in it onto the item, then the reader reads a 70 bit code with 15 extra 1's in it.... which is not the code that it's looking for, move along.

With a 3-10ghz range wireless reader, these would be the most feasible types of tags to use as a security device.
When entering a secured facility, you could get a unique card printed up and be allowed or denied access to rooms/areas via installed card readers. I'd much rather have a throw away card over biometrtics any day. And this such much more reliable over all.
And what about home security?
These could act as keyless entry, and also allow you to tag your belongings so that if they were detected as leaving your premesis, the authorities could be contacted.
There are plenty of 1984ish applications such as embedding these into ID cards/Drivers Licenses, which could in the future be a very effective way to monitor peoples comings and goings. But, I'm sure there are hundred of tinfoil cap wearing slashbts who could delve into those areas for me.

There would be real money in retailers being able to identify relationships between their consumers, too, and a clearinghouse could help them figure that stuff out pretty easily.
It wouldn't be all that expensive to implement, and isn't science fiction. As far as I know, it isn't against the law either.
The paranoid in me would also suggest that they could pay off Waste Management et al to install RFID readers so the retailers could figure out how long you keep your items before tossing them (which may actually be interesting information, but not something I am seeking to share with said retailers..)

But in all seriousness folks, this would probably backfire. The Fundamentalist Christians support the state of Israel precisely because they expect Armageddon to start there, and -- according to their Holy Book -- Armageddon has to happen before Christ returns to reward the Fundies.
That Armageddon is supposed to leave Israel hip deep in blood is one of those regrettably necessary evils. It'll be th blood of the Jews and the Muslims, not the Fundies. The Fundies will rule for 1000 years at the side of Christ, or rise bodily into heaven or however it is their Sky-Ghost is supposed to reward them.
Since another Sign of the "End Times" is the ubiquitous appearance of the Mark of the Best on foreheads or hands everywhere, I wouldn't be surprised to see Fundies being all for it, on the theory that the sooner the Beast comes, the sooner Christ follows.

I also wonder if they would make a good replacement for barcodes. Now that stores let you check yourself out, I have wondered if people bring extra bar codes with them. For instance, instead of paying for the 30 dollar bottle of wine, you swipe a bar code for the 10 dollar bottle of wine. Traditional RFID tags may be a counter measure to this, but this type of tag may not be.

It's definitely not something they could turn on today and have something totally useful in a month or two - it'd have to be in place for a year or more probably before it was pervasive enough to begin to be interesting. However nearly every item we buy has a UPC symbol now, so it's not unlikely that, as RFID becomes cheaper, every item could have an RFID tag in the future.
As an aside, I really dig the ideas people have proposed to combat this, namely having phony RFID serial number generators on their persons. Could make the databases less useful, and maybe not cost effective. Of course, getting enough people interested in "fighting" the technology would be a bit tough.
BS (Score:5, Interesting)
I believe that this company's technology is a hoax. The description from the RFId Journal page is nonsense. The CrossID [crossid.com] homepage is very vague and lacks any useful information (just read the last FAQ item at the bottom of the page.)
The description that the RFId Journal gives reads like pseudoscience. Here's an example:
The system uses "nanometric" materials--tiny particles of chemicals with varying degrees of magnetism--that resonate when bombarded with electromagnetic waves from a reader.
Some elements and molecules will resonate (emit electromagnatic energy [EM]) when exposed to EM radiation of a particular frequency, but only in the presence of a magnetic field! The process the article describes (without mention of the magnetic field) is that used by MRI machines. Why didn't the article or homepage mention the superconducting electromagnets necessary for the RFId tags to operate?
Even if the tag materials are magnetic (in which case its composition must be a ferrous metal, ceramic, or a magnetic plastic), then the very weak magnetic field is still not strong enough to cause the atoms/molecules to resonate in an EM field. Another sentence from article shows more inaccuracies:
CrossID is testing readers that operate at three to 10 GHz, which is higher than the frequencies commonly used by wireless LANs and handheld computers, although the company has not made a final determination on what frequency the readers will use.
They claim that 70 tag compounds are used which all have different resonate frequencies. Fine, the reader would use a wide-band receiver. I read the above as the tag reader using one transmit frequency. The trouble is that it is unlikely that those 70 compounds will all resonate when exposed to the same frequency EM waves. Anyway, it states that a "final determination" hasn't been made for what frequency to use! If the RFId tag ink exists then it MUST already be known what frequency must be used. This tech is bogus.
This article is just like the "Ubiquitous LED" article a few days ago. (if you want the reasons just reply) This article should not have been posted. It is not even wrong ;)

So that would seem to incline towards a control of the ink materials or production. I wonder how hard these chemicals would be to produce in a non-industrial setting?
I also wonder if the detectors could be improved to detect relative density -- of course that would just mean you need to do a little tinkering with the "eraser" so that it detects the signature and adjusts the masking mix . . .
Also, of course, having detectors capable of detecting relative density would increase the "namespace", though 2^70 already gives us ~200 million unique identifiers for each of 6 billion humans.
