OT So that is why (RFID Tag)

Barnes and Noble sticks those in the pages of their hardcover books, with a phony 'barcode' on the other side.

I make it a point to extract them and leave them in conspicuous places in the store.

It's fun to peel off the sticky ones and stick them to the backs of customers in front of me in the checkout line who are blathering loudly on their cellphones.

Just leave 'em sticky side up on the floor!

Sticky ones? Those are stickers!!?

Damn. I've been really missing out on some fun.

VHS Tapes, 'eh?

I presume those aren't the kind of tags that got "deactivated" by a strong magnetic field at the checkout counter.

Real fun is to catch an irritating co-worker who changes his shoes at work, and leave him a present (resonators) in the hollows of his shoe soles near the heels. Even imagining him going shopping after work is a hoot.

I don't see how. RFID tags are rendered neutral at checkout. If you take one off a purchased item post-sale, it's basically inert. Now, if you can get out of a store with one that is "armed", we'd like to talk with you :)

Just carry a small Al foil "envelope" into the store with you. The various tags are either RF-excited+RF-response or EM-excited+RF-response. Big envelopes will hide and shield the whole product and will make store security folks look at you funny. Fred

I recently saw a demo of RFIDs used to store the maintenance history of fire extinguishers. They have a small amount of memory that can be written to and read from with the right equipment. The idea with the fire extinguishers is the history is available to the fire extinguisher police ( not sure what they are called in Germany) just by walking past the thing. I think the advantage over just marking the tag like they used to do is that only someone set up to test the fire extinguisher can set the test info, whereas anyone with a sharp object can mark the tag.

We are looking at them to store protection relay settings and stuff on our equipment. From what I could work out, the store ones must send a code to the sensors in the store, and the checkout chick gives it a new code that says it's not stolen, of course I'm just guessing.

Wonder how long before they embed one of these suckers in the back of your head when you are born.

Rex, my method is deceptively simple. We get them by the thousands in a box. Some are hidden inside items. Someone has to put them IN the products, right? Now you see how.

I guess I could just carry them under my tinfoil beanie, then? Texas Parts Guy

The RFID tags only associate a unique number with a physical item. At the moment they currently do implant that tag on newborns - as a Social Security number. Same thing.

I think they are disarmed by placing them in a strong AC magnetic field at the checkout. The checkout counter usually has the magnetic coil concealed under a black rubber mat. Enough current is induced in the coil to blow a tiny fusible link built into the circuit. This kills the resonant circuit, making it unresponsive to the detectors at the doors of the store.

Jim, please tell us you are kidding. Texas Parts Guy

I'll take a wild guess that because the purpose of the RFID tags extends to tracking an item through its lifetime, not just to the cash register, the tag is not "zapped". Instead when you pay for the item, a database is updated to show that the item can leave the store without sounding the alarm, calling the police and electronically pre-booking you at the jail.

There's all sort of wild scenarios for these tags ... refrigerators that sense them, download the grocery stores' databases, then when your cell phone GPS sees that you're in the grocery store it text-messages you with a list of what you're out of ... etc.

You don't have that reoccurring wart at the base of your skull ? The operatives don't come out of the wood work and cops flipping a bitch to follow you forever in strange towns? Or the mark on your shoulder?

They use to be long metal strips deep in the pages of library books close to the binding.

Last time that happened was in New Orleans, but that's another story ;)

I guess that would explain the helicopters Texas Parts Guy

Most anti-theft tags (sensormatic is one of the biggies) are designed to be permanently inactivated once the item is out of the store. They either demagnetize the polarizing magnet when they are of the magnetic 'chirp' type, or they burn out a link in the coil/capacitor combination if of the resonator style.

Those tags don't have a unique identifying number, they won't squawk back to the base station the way a real RFID tag will. Putting one of those on mechandise to reduce theft would be too costly.

There is nothing implanted, of course. But in some sense the ubiquitous use of a SS number is *worse*. You could dig out the chip if that was how they did it.

Because an individual in the US can hardly do anything without their personal SS number, it might as well be tatooed on their forearm.
