Cheap, Paper RF ID Tags To Replace Barcodes? 168
Chris writes: "From EETimes:
"International Paper Co. and Motorola Inc. have developed a low-cost RF identification system that could become commonplace on disposable items like cereal boxes, replacing the ubiquitous bar code."
While the article does mention that the cost of the technology must drop further (from about 10 to 30 cents per ID to a couple of pennies), it overlooks the potential impact on privacy. (Just imagine embedding these tags in your clothes.)"

On the other hand we won't need to worry about the police asking people to describe the suspect. Instead of "He was a caucasian, about 6 foot 2 200 lbs, wearing a tan sportscoat and running shoes."

This same sportscoat was later scanned at 1610 Maple Street at Walt's Bar, and is currently believed to be in that area.
Theoretically, if you paid for your clothes with your credit card, the store would know that you bought the clothing. Those records could almost certainly be subpoenaed.

Slavery is alive and well in this country, and I'm not referring merely to rhetorical or political slavery, but actual slavery [examiner.com].

These women (and even children) are trapped, since they don't speak English, don't have the money to fly home, and don't have the physical or mental stamina to escape their tormentors after so much abuse.
How is this relevant to RF tags? Think of how much easier it would be to kidnap people from airports if all you needed to do was wander around with a small device, picking up the signals from the tags embedded in clothing given to the erstwhile immigrants back in their home countries. No longer would there have to be complicated networks of international communication -- they'd just have to agree on a certain range of serial numbers (of which there are trillions, as the article points out), hand out "free" clothes to people boarding the plane at departure, and sit back while agents at the US airports haul in the "goods".

Presumably a "portable EMP generator" might incorporate this (and not be just a 9V battery and a piece of wire)? Since I'm just talking hot air on this one, I'm going to say my imaginary EMP generator would.
Two - they can be used in conjuction with proven anti-theft technologies.
There is no "proven anti-theft technology" that cannot be disabled by a skilled and knowledgable person. Moreover, the problem is in using these with an automated cart-at-once checkout as seen in that (AT&T I think) commercial (this being the idea behind my original hastily-written post). That is, where you just roll your cart through the exit and it bills your credit card and prints out a receipt. No holding items up one by one to a camera or receiver or tag remover or deactivator.
Take a look at Sensormatics smartEAS - based on Intermecs chip.
I have. Those things are as big and bulky as current anti-theft clothing tags, meaning they would have to be removed at checkout. (The smaller versions look to be attached with adhesive, but that just makes them easy to remove.) I'm not sure how they can claim (as they do) that this will enable "automated inventory returns, active merchandising, self-checkout." I certainly wouldn't want one of those things in my undies poking me you-know where. Therefore, at some point (probably POS), it must be removed. (Sensormatic explicitly says this.) If they are going to sell "readers (fixed and hand-held), detachers and deactivators," what is to stop a disgruntled Wal-Mart employee from lifting a detacher/deactivator and turning it over for reverse-engineering and duplication? (I have, ahem, heard that this has already been done.) Anyway, this still prohibits the automated cart-at-once checkout idea, which was the topic of my original post, so these devices, others like them, and this entire paragraph are not really relevant.
Lastly - jamming won't work easily. The chips work woth frequency hopping interrogatorators.
Who said anything about jamming? Presumably Jamming would just be silly--it's a good way to get busted for shoplifting and get in trouble with the FCC. It's about as smart to disable the interrogators by kicking them over and ripping them out of the floor.
Anyway, the point of my original post was that attempts to use RFID tech to allow self-checkout leaves one open to abuse. Retailers know this, and that's why these RFID tags are probably just going to end up doing three things in the short term:
1) reducing the amount of time the clerk spends looking for the barcode and repeatedly trying to scan the same barcode-less side of an item,
2) providing better inventory control for retailers, though that is debateable (Why do they need to know which box of cereal sold? Because management says so.), and
3) creating more jobs for programmers to re-write inventory systems to handle the new data.
There is, of course, the possibility that retailers will find the level of shoplifting allowed by self-checkout and imperfect security acceptable in light of the ability to lay off a few clerks and shorten lines. Which, as I said, I think is a great idea!

This went on for several years because the US regularly ran bug sweeps but it wasn't generating or storing any energy most of the time, and when it was being powered from the outside, the US figured it was some sort of attempt at jamming telecommunications within the embassy (which it was doing a very poor job of, being at the wrong frequency) so they basically ignored it.
Anyhow, this is all relevant because these RF tags are powered by inductance, which means any range limitation is purely a factor of the EM field powering it. There's no inheirent limitation in the device itself.
As for privacy, I don't care about tags in my cereal box. If I can walk out of a store and automatically debit my account instead of waiting in line, so much the better.

It sounds to me like you are saying we should not use technology because it would put people out of work who, I assume, could not be employed in other ways. Should we keep a certain percentage of shit jobs around just so these unemployable people will have somewhere to work?
I hate to break the news to you, but business are run to make money, not employ people. Here's a note from the clue train: economics is not a zero-sum game... increased technology opens up far more jobs than it eliminates, as you pointed out. Should we keep some people doing dull grunt work so the rest of us technology-haves can live in our ivory towers or should we work to educate, train and enrich everyone.
Again, how is this any different from the ridiculous examples in my previous post? If I am so ignorant... please enlighten me.

Concentrating energy like that only works with light because of it's small wavelength. At these frequencies, your wavelength is measured in centimeters- you're not going to get a smaller spot than the wavelength without a LOT of trouble. Since a couple of milliwats per centimeter isn't enough to overwhelm the chip or burn anything, you're back to square one.

The name of the company, Flying Null, was due to the technique used. By setting up a region where competing EM forces were exactly balanced (a null), when tiny objects (the tags) with particular properties were brought into the null they'd disrupt the balance, and would be detectable. How do you scan a broader region of space? Simple - set up the balance differently, and get the null to fly around the place...
And the cost of the tags? In bulk, pennies, and that was 5 years ago.
(SG was 150 employees, about 50 engineers at the time, and only 5-10 were involved in Flying Null.)

Washer/Dryer == Disabler? (Score:2)
Is that really necessary? Wouldn't a normal wash/dry cycle contain enough abuse to disable the RF tag?
Privacy? (Score:2)
What's the effective distance on these things? I didn't see it in a quick scan through the article. It's not like they could scan your ID code from 10 feet away...

We've been throwing more good money after bad for decades... it's time for some real reform, because the next time a country like Japan eats our economic lunch, we might not be able to catch up.

Practical applications and limitations (Score:4)
On the other hand, it can bring about two major application uses: shoplifting is one, as this type of id would be harder to tear off compared to the various tags they have now. The other is from an AT&T commercial (I think), where you push your grocery cart into a stall, wait a moment, and your total rings up, speeding checkout lines. Possibly even 'smart' cupboards and refridgerators could come from this.
Sure, there's privacy issues in some of these cases, but they're the same privacy issues that we deal with now with those frequent shopper cards. The technology really doesn't introduce anything new.
