Big Brother Gets Smaller

Dude, I can see such inventory potential in that kind of chip.

Not to mention, a good way of determining a fake or illegal copy from a legit one.
 
Yeah, though I can see some good from this (hopefully more so than bad).

Like I said, I see it's potential in inventory or package tracking. Maybe a new way for FedEx or UPS to know where your package is. You know, like setting a transmitter/receiver where the packages come in to identify them. Might be more accurate/less fallable than the current laser-barcode scanners.

As for the government, this could be used for water-marking original copies or important documents.

I don't see too much potential for misuse, as a chip transmitter of that size won't be able to broadcast very far. Unless the RIAA wants to know who's buying what (or at least, who's being bought the most), and have a chip reader at every store they sell at. From what it seems in the article, it's not easy to manufacture the chips, so I don't see them being used to watermark every piece of paper to be printed -- only papers or items that are of much importance.

Maybe over time, if they improve the manufacturing and the range on the radios, then it may be a problem, but you'd still need something to activate the chip to make it 'talk'. I doubt those things are running 24/7. I could imagine the story:

Senator walks into Radio Shak holding a piece of paper, "Hey, how do I recharge my bill? I think the batteries are dead." :lol:
 
RFID was been used since quite a while i think, but these transmitters are really small.
For a package you wouldnt require such a small chip, the bigger one's would do it as well, but for things such as chocolate bars or even smaller products it's perfect.
 
and again we're paying more for the package we just throw away....
 
Just FYI for you guys who havn't been following RFID:

The tech is supposed to only be readable from a few CM, but recievers have already been made that will read RFID data from several yards away, big can-o-worms right there.

There is also some concern that these tags may not be deactivated once you leave the store as stated, enabling you to be tracked by your possessions.

The tech is being forced on consumers without them being told the dangers, even with a standard reader a nefarious character no longer needs to take your wallet, someone could just walk through a crowd and get potentialy thousands of different credit card, ID, passport and other numbers, without even touching you. The credit cards have been sent out already, my bank just sent me one with a note saying how wonderful it would be to not have to actually touch the scanner, and that my old card would be invalid in 30 days.

no technology ever stays limited to it's intended use, look at things like the bluetooth sniper, etc. If the tags are not deactivated this would not only enable the government or businesses to track you, but thieves could build a profile of you easily by your possessions and target you or your home.

These aren't just paranoia schemes, this kind of thing is already happening, this tech just makes it easier.

There is no power source, the tags are charged by RF, so wherever there is a reciever they can be read. It wouldn't work that great for document marking, as one could just encode a tag with the same info, like writing different info to a credit card.

well for document marking, the data in the chip would be a unique serial number, probably encoded with a very high security cipher(1024 bit or greater) that would be protected by the company who's document it is.

I welcome RFID (partially because it actually makes life easier), but I won't be trusting it with my financial information just yet. It's also fine if it's encrypted, or if it's a serial number on the card that links to a database in order to look information up, preferrably with high strength ciphers.
 
So just copy the data bit for bit? Works just fine with credit cards, hotel room keys, IDs, passports, etc. etc. These techniques are already being used, RFID just makes it easier to exploit remotely. People don't need to mount skimmers to ATM machines anymore, they can just hide one nearby, or sit in a car with a good antenna(see bluetooth sniper). Financial data is already encrypted and tied to an internal database 98% of the time, but if you copy the data none of that matters, because you have an exact clone of a legit card. Trust me on this, I have been involved in security for around 8 years.

I still don't see how getting the card close to a credit machine instead of actually swiping it makes it any easier. For inventory tracking it's just fine, but don't expect it to work against thieves. Also there are other implications beyond simple inventory tracking that I have outlined. I don't want to blast all my possessions with RF to destroy the tags on everything I buy.

RFID is also going into passports and license plates.
 
Thousands of people are already using RFID tags in "Fast passes" on toll bridges. I welcome RFID tags because they are already here.
 
RFID passive tags: The simplest tag is the radio frequency identification (RFID) passive tag, which supplies no more than its own identity, the 64-bit value, when read. The manufacturing process for the least expensive RFID tag etches a different number onto each tag that is unalterable.

Power for the RF transmission of the tag's ID data field comes from the reader that emits a low energy electromagnetic field (EMF) in order to power the tag. When the tag energizes by being in this EMF radiation, it repeatedly transmits its own identity field value. A recent variation on this protocol allows the transmission to occur only once after a fixed time delay unless it detects a query message generated by the reader. This allows many tags in the same field of the reader to register individually.

The value of the RFID passive tag is approximately the same as for a barcode; the tagged item has a unique identity. The data for the tagged item is usually located in a computer database, not on the tag. Simplicity of the tag keeps the cost at a minimum.

However, the fact that the RFID tag needs only to be located within the EMF field of the reader, not necessarily in a direct lineof-sight as required to read a barcode, enhances its functionality for item tracking over barcodes that need direct line-of-sight to the reader.

The RFID passive tag in the form of a credit card works now in automatic fare collection for public transportation systems. The card is similar to a magnetic stripe identity card, except it does not need to come into physical contact with the reader, only near the read station.

RFID active tags have an on-board battery enabling higher power transmissions to cover longer distances. Reading an active tag is usually a transaction in which the reader continuously polls to determine if any tags are within its reading range. Often, an electromagnetic field comes from the reader signaling that it is ready to read the active tag. When the tag receives the poll read-request, it returns its ID value. This pattern avoids wasting the active tag's battery life since the power required to receive is far less than the power required to transmit a signal. Because the reading range of an active tag is usually much larger than for a passive tag, there is a strong likelihood that more than one tag will be within reading range at the same time. A reading protocol usually exists to make sure that only one tag clocks in at a time.

The most common uses of active RFID tags are in automatic highway toll collection and in tracking of railroad boxcars. Some systems, such as EZ-Pass and FastPass, use active RFID tags that are readable at distances of up to 10 meters when located behind the windshield of an automobile.

In North America, all railroad freight cars carry an active RFID transponder as part of the Rail and Intermodal Asset Tracking System. As the rail cars pass in front of readers located at strategic rail switching yards scattered all over North America, their identity is read and reported to a common tracking system.


RFID programmable tags: "Programmable tags"is an old name but means only that the user can write the ID number on the tag. Most often, the technology used is the Electronically Erasable Programmable Read-Only Memory (EEPROM). Both passive and active programmable tags are available, although the use of these tags is diminishing and giving way to more connected databases using RFID tags or by more flexible RF Data tags.

RF data tags are readable, and one can write to them. Usually there is an ID field of the same 64-128-bit length as for both passive and programmable RFID tags, but there is extensive read/write memory located on the tag as well. In all cases, RF data tags are active with a long-life battery on-board. They generally have a read range equivalent to other active tags, up to 10 meters, depending upon the reader's antenna gain. Writing distance is less, typically to about 3 meters. The read/write memory is usually Flash RAM with capacity up to 256 Mb. Flash memory is usually organized into blocks similar to disk and is supported to maintain a file system similar to that used for disk drives. RF Data tags are similar to USB memory devices except for the wireless connection to an RF reader. Flash memory does not require battery power to retain data. Read and write speeds for RF Data tags with Flash RAM are comparable to that of USB memory, slower than disk drives.

It is also possible to produce a high performance RF Data tag using battery-powered CMOS RAM memory. Read/write times are similar to that of computer main memory; however radio speeds necessary to actually use this high speed memory are not attainable. Although it does not require much power to retain memory in CMOS RAM, any loss of battery power erases memory content. Therefore, there are no commercial RF Data tags using CMOS RAM.

Location tags or beacon tags are proprietary VHF radio devices that usually attach to pallets or containers stored in a large flat warehouse space. The tag generates an intermittent signal with the tag's ID value that broadcasts throughout the warehouse space. Usually, the tag is equipped with a motion sensor so the interval between broadcasts becomes shorter when the tagged item is in motion. Readers are logistically located at the corners of the warehouse space to receive the RF signals. When a reader receives the beacon from the tag, it also receives the strength of the signal, indicating the approximate distance between the tag and the reader. In order to map the two-dimensional location of the item in the warehouse space, the beacon signal identification and signal strength must simultaneously read into a second reader.
 
Your point? These tags are different, yes they use RADIO FREQUENCY but they are not the same as the fast pass systems, they are all types of RFID but not the same. Get it? Furthermore the actual technology isn't the problem, it's the questionable uses.
