Do It Yourself a RFID immobiliser

Sunday, May 2nd, 2010

rfid-car-immobiliser

This guy, [andrew_h] has put together this slick anti theft device for his car. This RFID immobiliser is used to keep the car engine from starts unless you swipe an RFID tag. Depending on how well you hide it, and how well the person stealing the car knows you, they would have no reason to suspect that they have to swipe the tag. Even if someone steals the car while it is already running, they won’t be able to re start the engine if they shut it off. Guys, you should try this one if you have any car to experiment with, or you have to steal a car to do this.. kidding! All steps, schematics and PCBs are available.

How to build your own RFID reader

Thursday, April 22nd, 2010

DIY RFID

Do you have any idea on how easy it is to build your own RFID reader? Well, we stumbled upon some sites that’ll give you some clearer picture on how to make this thing happens. As pointed out by hackaday,

[Klulukasz] left a comment pointing to this DIY RFID reader that was a final project in 2006 for a class at Cornell University. It is well documented and includes not only a schematic and code, but an explanation of the design considerations used during the build. The project uses an ATmega32 and the parts list priced out at about $50 at the time. There were plenty of responses to theRFID spoofer post pointing out that there are readers available for $40, but we want the fun of building our own.

A bit more vague with the details but no less interesting is this other simple RFID reader design.

RFID tracking system

Wednesday, February 24th, 2010

This is a working tracking system using RFID tags built by Nicholas Skinner. The system’s tags operate in the 2.4 GHz band and are used to track either people or assets. The readers are on a mesh network and can triangulate the location of any tag for display on a map. His system is even set up to show the travel history of each tag. [Nicholas] shared every detail in his writeup including some background about available hardware options and how he made his final decisions on what devices to use for the job. His conglomeration of software that ties the whole project together is also available for download.

Feds at DefCon Alarmed After RFIDs Scanned

Wednesday, August 5th, 2009



rfid_4-300x200.jpgLAS VEGAS — It’s one of the most hostile hacker environments in the country –- the DefCon hacker conference held every summer in Las Vegas.

But despite the fact that attendees know they should take precautions to protect their data, federal agents at the conference got a scare on Friday when they were told they might have been caught in the sights of an RFID reader.

The reader, connected to a web camera, sniffed data from RFID-enabled ID cards and other documents carried by attendees in pockets and backpacks as they passed a table where the equipment was stationed in full view.

It was part of a security-awareness project set up by a group of security researchers and consultants to highlight privacy issues around RFID. When the reader caught an RFID chip in its sights — embedded in a company or government agency access card, for example — it grabbed data from the card, and the camera snapped the card holder’s picture.

But the device, which had a read range of 2 to 3 feet, caught only five people carrying RFID cards before Feds attending the conference got wind of the project and were concerned they might have been scanned.

DHS proposes funky ‘fix’ for RFID security

Saturday, November 15th, 2008

A proposal by the Department of Homeland Security attempts to address one potential security problem with RFID-chipped passports, but leaves more obvious problems hanging fire.

In an effort to detect attempts to clone the data stored on RFID chips used on US Passport Cards, DHS on Wednesday announced that it is recommending that manufacturers supplying these RFID chips include a “unique identifier number,” or Tag Identifier (TID).

The TID would be used to ascertain when a chip’s data has been cloned, as one would do to create a fake passport. If two passports with the same identifier number turned up at the border, one of them could be deduced as fake. That number would actually be the second unique number in the chip, since all a passport’s RFID chip stores is a unique number that is indexed in a database. (Currently the chips hold one unique number and one generic manufacturer code; that generic code is the one that would be replaced with a TID.)

It’s an identification model that works reasonably well with mobile phones and automobiles, but an identity document is a different creature. Conceivably, the ID number might help to determine whether, for instance, a hacker intercepting the snail mail has waved a reader near a State Department envelope and picked off the data without having to open the envelope — with “contactless” technology, the envelope would not have to be opened. But the model may not help with other security issues RFID researchers, privacy activists, and anti-terrorism experts have flagged. (more…)

Scratch built RFID tags

rfid.jpg

[nmarquardt] has put up an interesting instructable that covers building RFID tags. Most of them are constructed using adhesive copper tape on cardstock. The first version just has a cap and a low power LED to prove that the antenna is receiving power. The next iteration uses tilt switches so the tag is only active in certain orientations. The conclusion shows several different variations: different antenna lengths, conductive paint, light activated and more.

Thai researchers adopt RFID to track fish breeding

Saturday, August 16th, 2008

Fishery researchers in Thailand plan to adopt an RFID-enabled system to track the broodstock – the fish kept isolated for breeding purposes – of several fish species key to the country’s export business. With the system, researchers can track the development of the broodstock and supervise crossbreeding programs to improve the species.

Researchers at the Department of Fisheries Science at King Mongkut’s Institute of Technology Lad-krabang are embedding RFID chips in three aquatic species, the Giant Prawn, Nile Tilapia and Walking Catfish. The three species are crucial to Thailand’s economy, with an export value of about 2 billion bahts a year.

Since last year, the team has embedded RFID chips into more than a thousand of the three aquatic species. Researchers are working to determine the least disruptive way to insert the tags into the tiny juvenile creatures. To keep the system simple, the tags will only include a serial number to identify the individual. Other information, such as the animal’s breed, its growth and diet, will be maintained in a database.

“We will track an animal’s growth on a monthly basis, to monitor its overall development. The software will help us analyze the data. If we find that the animal is not growing well, we will implement cross breeding to improve the species,” said project leader Rungtawan Panakulchaiwit.

The project has received funding from the National Electronics and Computer Technology Centre, as well as support from two private RFID companies, Silicon Craft Technology and IE Technology. After the pilot program is completed, the research center plans to promote the technology to private aquatic-animal farms across the country to help improve their farm management.

RFID to test Indian driving skills

Sunday, July 27th, 2008




The Regional Transport Authority of Hyderabad, India, has announced plans to monitor its driving test tracks with an RFID-enabled system designed to automate testing for driver licenses.

The new system will be tested in a pilot program at one of the RTA’s three test tracks. The Nagole track will be equipped with a set of RFID readers buried 15 inches beneath the road surface. Applicants for licenses will drive vehicles outfitted with antennas, and the system will track variations in movement, speed limit and wrong turns within parameters preset by the RTA. Test scores, and the prospective driver’s ability, will be judged in a graph format.

The system takes human judgment out of the test administering, after accusations had been made that driving school agents and motor vehicle inspectors were manipulating test results. As additional insurance, thumb impressions would be recorded on the driving license to avoid manipulations

“No discretion is given to a motor vehicle inspector or others,” transport commissioner Raymond Peter said. “Once we see how it works, we will computerize the rest of the tracks. The system will be in place after the monsoon.”

RFID-enabled crop tracking

Saturday, July 12th, 2008

RFID producer Intelleflex Corp. has announced a joint solution with Minds Inc., a information systems provider for the road construction and agriculture industries, to create a system that would automate tracking of crop harvesting.

The solution combines GPS, RFID and wireless communications technologies to provide real-time visibility into the time-sensitive operations of field harvesting. Using this solution, growers and harvesters can track the exact location, timing and efficiency of harvesters, as well as the arrival, loading and departure time of crop transport vehicles.

“In the crunch of harvest time, people are focused on the task at hand (i.e. the harvesting of crops), and not the tracking, recording and communications of operational data. As a result, there is often a lack of the information required to ensure the most efficient operation,” said Pierre Vidaillac, president of Minds Inc.

In the new system, GPS units and RFID readers are mounted on harvesters to track their whereabouts in the field as well as the arrival, loading and departure times of transport vehicles. The information is then transmitted wirelessly for immediate access over the web and mobile phones.

Intelleflex and Minds Inc. have previously collaborated on a similar system which tracking hot mix asphalt for the road construction industry.

Printable RFID??

Saturday, July 12th, 2008

A research group in Europe has taken a major step towards the goal of developing printable electronics that can be used for creating RFID tags. Researchers in the EU-funded CONTACT project have demonstrated that with suitable inks and printers, organic liquid crystal displays and other optical electronic devices can be printed out precisely.

The project researchers hope to follow this proof-of-principle by developing a gravure printing press, called Labratester 2. The press will be able to print hundreds of thousands of organic thin film transistor arrays or other devices precisely and efficiently.

The end goal of the project is to establish the ability to print electronic components directly onto organic materials such as paper, fabrics, or plastic. This would allow the quick and relatively cheap printing of RFID tags, as well as everyday devices such as flexible watch displays, and could eventually lead to applications from the realm of science fiction, like electronic paper or eyeglasses with embedded displays.

Participants in the CONTACT project include Switzerland-based Schläefli Machines, the Technical University of Ilmenau, Belgium’s IMEC, and Imperial College London.
