NYT on RFID
The New York Times has a piece on RFID tags. It's basic, but worth reading as a milestone - the technology is starting to enter the public eye. These RFID tags will have unique serial numbers - every RFID-tagged item you purchase will be uniquely different from every other nearly-identical item, enabling it to be identified and associated with you long after the purchase. And no, microwaving will generally not destroy the tags, and no, most items won't be microwaveable anyway. Try to microwave your couch.
But How does it benifit the end user, oh wait I don't have to wait as lon in the checkout line with five screaming kids and a trolley full of sofas
No, I didn't RTFA, as it requires a requires a registration. My question is, how long do the power sources in these things last? The link to EPC global did not answer that question.
Why aren't RFIDs used for baggage handling at airports? In Europe all baggage of a passenger has to be removed from the plane if this passenger does not board. This may lead to delays because they have to sift through every piece of luggage.
RFIDs should make this much easier...
We may not be able to stop companies from putting RFID tags on their stuff, which becomes *our* stuff when we buy it, but we sure as hell can find these tags and remove or destroy them after purchase.
How difficult would it be to build your own RFID detector? If it is too difficult for Joe and Jane Average, how much might one cost at WalMart/Target/Walgreens/geektoys.com?
Somebody want to start a business making these? I have a manufacturing background...
For RFIDs to be exploitable in the way many seem to think they will be, and for them to be at all useful in a similar manner to bar codes for taking product inventory and the like, they're going to have to have a very generic way of checking the code. Otherwise the store is going to need several readers to check their stock, and the whole usefulness of the scheme will be lost.
If they can read it easily, you can read it easily. It's just a matter of getting a much lower power transciever or tweaking the wavelength in an existing one to manipulate the distance of the read -- you can easily narrow down the position of an RFID tag in an object if you have a modified reader that only works from a millimeter away, right?
Try not. Do or do not, there is no try.

I have to admit, I can see why retailers would want to exploit RFID tags. It would save them a lot of money in labor, as well as reducing the load on any loss prevention manager. This boils down to either more profits or lower consumer costs.
I have three opinions about them.
1) Everything you buy that contains an RFID tag must be properly labeled. The consumer should know what they are buying.
2) There should be a way to easily disable them after taking the product home. Ideally, they should be deactivated on your way out the door, but there are complications(non-technical) hindering the store's choices.
3) Any product that has a unique characteristic or property shouldn't have an RFID tag. For instance, if I go to the local Sears, Home Depot, Lowes, whatever and buy a personal fire safe(w/o the changeable combinations), I wouldn't want the safe to have it's combination somewhere indexed to the RFID chip's serial number. There is a greater security risk here, this is but one example.
You can't legislate goodness. Let each to his own destiny, by will of his freely made choices.
I'll worry about this when someone makes a reader that works well when several tags are in the field at one time. Currently farmers downunder are getting RFID tags for all their cows and most sheep. The farmers are sort of sold on a concept like Mr Spock's transponder saying Bessy is 126 meters at heading 74 with an arrow pointing at the cow. The problem is the current readers are good to read a cows tag at nearly .5 meters and when you consider how wide a cow is there is a bit of a problem.
In an unrelated subject, if someone has any clue about RF and DSPs and pulling several cruddy analog low powered alalog signals out of the either, I know someone that would like to talk to you.
Not so long ago, we had a story here in the Netherlands where a shop was able to locate people who bought a certain item, which was poluted by someone wanting to damage a company, because these people had used a bonus card, with a unique number identifying them, and because the shop did register who sold what. Some people had become seriously ill after eating the contaminated product. Luckily, they all recovered.
If a manufacturer wants to stop resale of it's goods on the second hand market (think: CD, software, E-book) it says so on the packet and puts a unique RFID into every item.
Then it goes round the car boot sales and picks up the items (doesn't even need to buy/touch them - scan as they walk by), tie back to the original sale (you did pay by credit card didn't you ?) and hit you with a court case.
Result: more profit

They are going to put these in tires. When you buy your tires the seller is going to be required to enter your information in a database.
One day when you are going a little too fast in a school zone or run a yellow that switches to red too fast an underground computer is going to sense the rfid in your tire, immediately reporting the number via rf link to police headquarters.
You would think that this would be for the purpose of giving you a ticket. You're right, you will get a ticket. But that is not the end the trail for your rfid number.
It immediately gets sent to the state government where it checks to make sure you are not a deadbeat dad that the wherabouts of are unknown. Simultaneously sending it to the FBI to see if you are a name on the "patriot" act watchlist and indexes your location. If you drive on the same street on a regular basis they will know where to find you.
You're not a deadbeatdad, lawbreaker, or terrorist you say??? Well the trail that your rfid number takes does not end there. Your rfid number is sold by cashed-strapped states to a commercial database under the auspices of "risk mitigation" that insurance companies subscribe to. Because you were speeding, you are at an increased risk and your car insurance rates are subsquently raised. Because you drive dangerously, your health insurance rates are also raised. Maybe they cancel your policy outright.
You're thinking I'll just remove the rfid. No you won't. Driving with unregistered tires is against the law, and if the police can't scan you as you drive past his cruiser he pulls you over and immediately suspends your license and impounds your car. But you won't be able to remove it anyway, without destroying the tire, as it is purposefully integrated with the "steel belt".
Does the trail end for your rfid tire number now? No, it most certainly doesn't. To see where it leads further, you are going to have to talk to my patent attorney.
Take the cheese to sickbay, the doctor should see it as soon as possible - B'Elanna Torres, "Learning Curve"
I just bought the C&C expansion pack, Zero Hour, and inside the CD case itself (behind the front label) was affixed the standard little rectangle (to trip sensors in case you try to steal the game) but underneath it was a 1.5x1.5 RFID patch. This is the first time I've seen an RFID tag used for videogames..
