Hacking the RFID Network

An anonymous reader writes "The world's largest retailers are developing the EPC Network as the infrastructure for a global rollout of item-level RFID. In many ways this 'Internet of Things' resembles the ISBN system or CueCat's codes-to-content. But the network built for tracking consumer goods could also be used for intangible items: airline seats, music tracks or service calls."

    on overusing this new system

    Track music downloads and service calls? That's billions of unique items every year. How many items do these RFID tags support?

      Well, there is 96bits on info on the tag (the 64bit tags are already just about dead). The reprogrammable tags (unsecure) will have something like 196 bits of scratch space. Secure tags are laser programmed. Of those 96bits, some are dedicated to the same functions as the old UPC codes. But you can imagine 48 bits as a serial number. There are various EPC standards proposed that will dictate how many bits are dedicated to each data type.

      I propose we begin tagging RFID tags with RFID tags, and feed the data into a meta-tracking database.

    this is what I learnt about the system from a cursory read of the article:

    What they're saying is that RFID can be applied to intangible information - content rather than the physical media - just like ISBN/Library_of_Congress system uses an identifier for a book rather than an instance of it.

    In other words: RFID can be extended to apply to an entire class, rather than instances of it, as is usually done.

    Bet somebody'll mention how this is great for pr0n in the next 5 minutes.

    The major shortcoming of RFID tags is not their rollout in stores, it's that they want to do things like weave them into clothing fabric or hide them so you've got to work to get them out. I don't know about you, but that's a bit excessive. Moreso, the range on the tags is an issue; the tag may be tiny, but you can still get a considerable amount of range out of that, look what's possible with GPS.

    Then we've got the registering everything idea. If we put RFID tags on everything that can go for 100 feet, and if everything has a unique identification code, then the government can ask for a list of which codes are associated with which objcts. Then, as stuff is baught, you swipe through your drivers lisence and a database is updated with what you have. Combine this with bank account data, wifi hotspots on poles that are constantly pinging devices, garbage trucks equiped with rfid scanning technology, and other pieces of information, and you've got one hell of a spying system. All those evil laws the people in power dream of would be possible.

    If there was a law that said the RFID tags could only be put on removable stickers, and must have a range limited to less than 5 feet, then it'd be ok. It's the "weaving them into products" thing that's got everyone upset. Infact, if that weaving thing didn't exist, I think RFID tags would be pretty neat; you could buy a bunch of food and query it through your house, which could download and update a database of recipe's which could be setup on some kind of whacky algoritm that figures out which is going to go bad first.

    The only problem there is that as the chips evolve, we'll be throwing small flash cards on em with advertising or more complicated systems of ensuring produce hasn't been tampered with, which if the laws don't change, will require licensing since you're copying; licensing to eat, not a good thing.

    AS far as tracking people is conserned, we all know of the mark of the beast, and we all know that tracking accounts with rfid tags is just plain stupid. If you're going to track a person, have them wear a wrist band or something; even the guys on star trek didn't have that little pin thingy embedded in their forhead.

  7. A good use for existing RFID tags by Alaska+Jack · · Score: 5, Interesting

    It's my understanding that a common practice these days is to have microships (which I assume to be RFID tags) injected under the skin of pets, so lost pets can be identified even if they're not wearing collars.

    I think a good idea would be to make pet doors that can "learn" to unlock only when certain RFID tags are within 4 or five feet. You could set it for the pets you own, and other pets (and/or other critters) wouldn't be able to get in.

    Also, if your pets didn't have the chips implanted, you could just get a chip on a collar.
