Now it’s barcodes that can be read at a distance
2009 July 28 by Mark Baard
Radio frequency identification tags are not fully catching on, thanks to objections from Alan Watt, Katherine Albrecht, and others who have been hammering away for years at RFID’s threats to privacy and civil liberties.
For global corporations and the US Department of Homeland Security, who remain eager to track individuals, that means it’s time to shift their efforts back to barcodes.
MIT scientists last week said they’ve overcome the barcode’s strongest privacy protections - its close read range, and fussy need to be scanned, line-of-sight. Now, using the camera in a mobile phone, a spy, or hacker, will be able to scan the barcode label on any object, or person, at an angle, and up to 60 feet away.
The MIT scientists are working with grants from Nokia, Samsung, and the Alfred P. Sloan Foundation named for its founder, the ruthless auto industry chief that one reporter counts among “Hitler’s carmakers.” Sloan is also a creator - through his strategy of “planned obsolescence” - of our modern, consumerist culture.
The new barcode labels, called bokodes, can be made “tiny, and imperceptible“ - each is about three millimeters in diameter.
Here’s an excerpt from the BBC:
“For traditional barcodes you need to be a foot away from it at most,” said Dr Mohan.
The team has shown its barcodes can be read from a distance of up to 4m (12ft), although they should theoretically work up to 20m (60ft).
“One way of thinking about it is a long-distance barcode.”

The funny thing here is that I stopped carrying ALL cards last year and was telling people that barcodes and magnetic strips could be read remotely and have been for quite somne time. Got a few of the usual skeptical reactions but going to show this to those people and see what they think now hehe! Unfortunately some people are so deeply asleep that no matter how much evidence you show them they will continue to deny...
Anyway, to me this is yet another example of the old "yeah we got it but we're not gonna reveal it till the time is right". I guess the time is right on this one now they've got everyone so into things like "One Cards" and they've installed all the remote readers everywhere - oh sorry, "anti-theft devices" at the exit to every big store, etc (yeah right, good one!). :wink: |

And further (just for a laugh), I had the misfortune of having to go into a K-Mart a couple of times over the last week. Both times as I had just finished a transaction at the counter I was asked what my postcode was with no further information. The first time I asked what it was for. The reply was "oh 'they're' doing a survey...". I said no, thanks, bye. The second time I was asked I just smiled and replied "No. I prefer not to contribute to corporate data collection, thanks." The lady behind the counter just laughed as she made eye contact, breaking from the monotonous tone she'd been using during the whole time I'd been standing there. Clearly she wasn't used to hearing anything other than small talk banter & unthinking automatic response! I was glad to have very briefly given her a tiny break from that heavily programmed monotony LMAO! :D
PS. I very quickly used cash of course after waiting ages for the line of card-users taking WAY MORE TIME to drag cards out and punch numbers in, at least 2 of them having to wait for the machine to say their transaction was declined so that they then had to drag out another card and try again. Cards more convenient? Uhhhh nah, SUCKED IN! |

Ever seen the barcode on the registration label of your car?
When was the last time you remember it being read? and by whom and where? |

Good call secondfield :wink: They do have quite a heavy-duty looking barcode on them and one has to wonder what the real purpose of this actually is especially given the now public release of the info above. And you're right - don't they scan the tear away piece of your rego when you "buy" them and not the main rego card? Or is it both? I can't remember now. Either way, all that's really doing is putting the info into the database - from then on any subsequent scanning would link you to that data.
I guess you could always place a strip of lead impregnated tape across just the barcode bit to be on the safe side :D Maybe on the inside of the windscreen just above where the barcode is so you can't ever get blamed for defacing your rego lol! I know you can get little envelopes for your bank & credit cards that are lead lined and supposedly stop any scanning of the cards inside it. Personally I just don't carry cards anywhere with me anymore unless I absolutely have to for occasional work purposes - cash is way quicker and a lot less hassle imho!
Oh and while we're on the subject - is anyone else getting really sick of the One Card thing in supermarkets now? Most of my shopping is done in the local organic store but one or two supermarkets around here have decent enough organic aisles to make them "after-hours" back-ups. I walked past the supplement section the other day in one and at least half of all the Blackmores range had One Card labels on them reducing the prices between about $1 - $12! When you look around there's tons of stuff now with One Card labels on them. I'm predicting that before long nearly every item instore will have them (we're just about there now!). I reckon this works well for them in so many ways - they can put their prices up more often now unnoticed by the large majority of customers who are just looking at how much they're saving off the "full price" with their One Cards and obviously it'll mean just about every customer will have to get one in order to be "part of the in-crowd" and to be able to afford to shop there! I guess as much as I'm sick of hearing "have you got a One Card sir?" I'm also starting to run out of reply lines like "No, luckily my name isn't in your computer system" or "No, I prefer not to have my every visit & purchase logged in the database" 8) |

| nice answers crakka i am heartily sick of being asked also. and i have definitely noticed a marked increase in only one card users can make use of the "specials" since it first came onto the scene. do u have flybys :twisted: |

Hehe! That's the line you get in every petrol station eh! You just can't get away from it now no matter where you turn. And yes, the number of non-OneCard specials is dropping rapidly as the OneCard tags take over! I was thinking at one stage of even trying to sign up for one as a joke with completely bogus information and saying I was of no fixed abode for my address - but the thought of buying into it even at that level left me feeling nautious LOL! |

Hi all,
I have a US client who is heavily into extracting number plates, serial numbers and such from moving vehicles and shipping containers.
Their current technology allows them to read a 2D barcode from 120 ft away in the outdoors.
I was talking with them about this technology and what's in the pipeling:
http://www.consumertraveler.com/today/new-iris-scanning-system-scans-30-passengers-per-minute-at-a-distance/
We now live in a world where your retina can be scanned from a distance without you even looking into the camera.
I thought you all should be aware of this because in this context, I'm not too sure how much of a big deal it is protecting your magnetic cards etc.
I've also worked with RFID technology as personal tracking devices where it's used in places like prisons, mines and now daycare centers in the US.
It is my opinion that these technologies will be widely utilised within the general population as a means of control as governments seek to maintain the status quo.
I suggest you all read Martin Armstrongs writings on the economic confidence model and the rammifications for the next 10-15 years. |

Thanks for the input Farside. Haven't had a lot of time to dig further into this field lately. As you can see the last posts here were in 2009 so obviously technology has advanced even further since then.
One question that comes to mind is whether or not those 2D barcodes have to be in line-of-sight to be read? I would imagine so. For instance, if your barcoded information is in a wallet or bag or just covered with something else can they still be read? However, I also think barcode technology is very much the lowgrade tech we're sold in lieu of much more advanced, more undetectable & foolproof techniques including such things as nano-tech.
Also, is there a similar requirement for iris scanning? I note that linked article says "IOM systems deliver accurate identification regardless of whether the subject is wearing prescription glasses, most sunglasses, or contact lenses." It would be interesting to find out what kind of eye coverings would block or cheat this gross invasion of privacy.
Bottom line is some people will always want to take action to prevent their information being "extracted" without their permission.
Mind you, most people don't even realise they're agreeing to ALL of this stuff whenever they make any transactions to purchase, travel, etc and many do but don't think it's a big deal. So well-trained aren't they?! |

| Always wondered why they had those funny looking barcodes on your vehicle registration label (mounted inside the windscreen), when I never once saw on being read by a conventional scanner. |

Good spotting chaps!
Not all the sheeple are wooly headed!
It has been in popular fiction, but because I don't even do films anymore I couldn't tell you which one - but apparently in it the protagonists car is spotted via some satellite system and the bad guys pounce on 'im in two tics of a laaaambs tale.
Resistance is futile. :lol: |

Notice it says most sunglasses. This is a key indicator that some prevent reading and my guess would be polarized lenses.
As far as barcodes are concerned, they definitely have to be line of sight (unless there is an RFID embedded in the label).
There are two big technical challenges facing nano-tech and they are the ability to fabricate transmitters and power supplies.
The only way we know how to create a transmitter requires some sort of RF circuit which needs wire coils. The more power you want (to transmit over a distance), the bigger the wire coils. Although a nano-scale transmitter could be built, it wouldnt have the transmission power required to send data further than a few centimeters.
The bigger the transmitter, the bigger the power supply needed too. |

| There is a way to energise a 'passive' circuit. The use of diode arrays called 'Rectennas' (rectifying antennas). These micro arrays collect AC waves propogated as RF (radio frequency) and convert them back into DC current to momentarily power any transmitters that are energised in this fashion. A Radio broadcast or microwave signal of sufficent energy is beamed at the passive RFID from a distance the Rectenna collects the RF, rectifiys it to DC and then powers up the devices tranmitter with this charge enabling transmission of its telemetry burst. |

| At higher frequencies (Ghz) coils LC / RC networks are not required, they layout of the PCB (printed circuit board) is done in a resonant / geometric fashion enabling passive power gain (much like the structure of a resonant antenna) via geometry. Like the Pyramids but on a tiny scale. |
