Do It Yourself a RFID immobiliser

Sunday, May 2nd, 2010


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.

iPhone RFID Reader

Tuesday, March 16th, 2010


The idea behind this project is to see what the iPhone’s serial is capable of and to try and have a little fun with RFID along the way. This reader works with the low frequency (125Khz) tags but I have a half working version for MiFARE Hi-Frequency as well.

For this project you will need:

  1. An iPhone USB Cable (genuine one is best and probably at least 3!)
  2. A JAILBROKEN iPhone!
  3. An ID-12 RFID Reader
  4. An ID-12 Breakout Board
  5. Logic Level Converter
  6. It’s useful to have some IC Sockets for Soldering
  7. Glass Tags if you want extra fun or any
    125Khz Tags
  8. If you don’t like the idea of taking iPhone Cables apart, use an iPhone Breakout Board
  9. A Battery Pack with a 5V step up
  10. Wire.
  11. Some kind of switch.
  12. A box to put it all in.
Wow, is it really enough to finish the job? All we need is some determinations and courages – well, i think so! Check out this video!

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.

RFID emulator

Wednesday, January 6th, 2010


[Alexander] built an RFID emulator. It uses a wire coil (not pictured here) and an ATmega8 to represent any tag that is EM4001 compliant. This iteration requires connection to a computer to send the tag ID information to the microcontroller. In the video after the break it looks like he’s using a DIY RFID reader to test this. If the two were combined, cutting out the need for a computer, he would have an RFID spoofer on his hands.

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…)

How to Succeed with Real-Time Location Systems

Saturday, November 15th, 2008

An Awarepoint white paper describes critical factors required to maximize your RFID system’s return on investment.

Real-time location systems (RTLSs) are an increasingly important strategic capability for a variety of business applications. RTLSs allow organizations to efficiently identify and track the location of supplies, personnel, equipment, and other items in real-time, as a cost-effective operational management tool.

With the success early adopters have had with RTLSs, the question is not whether to implement, but which technology is best suited for the many applications that can benefit from location awareness. An Awarepoint white paper, “Considering a Real-time Location System? First Consider the 5 Critical Success Factors,” can help maximize your return on investment and ensure long-term success of your RTLS investment.

“The implementation of RTLS technology should pay for itself as a result of shrinking the incidence of misplaced equipment, decreased rental costs, and increased utilization of equipment,” stated Jason Howe, CEO of Awarepoint Corp.

The five critical factors outlined in the white paper to obtain maximum benefit include:

  • Enterprise-wide coverage—because assets and people move throughout your entire enterprise, to achieve maximum benefit, your RTLS deployment must cover every square inch of your enterprise.
  • Location accuracy—to affect the highest impact for your strategic initiatives, room-level accuracy is a clear critical success factor.
  • Installation and maintenance—a minimally invasive solution that does not compromise your existing IT network, does not interrupt daily business operations, and can be installed in days or weeks, is vital. Maintenance impact for hospital staff should be considered as well. It shouldn’t take a team of IT professionals to keep the system running.
  • Interoperability—your RTLSs should be supported by standards-based technology and should offer an open application programming interface so that it’s capable of providing location and status data to both your end-users and to third-party applications.
  • Low risk—you should partner with a vendor vested in your success. Look for a flexible business model that doesn’t require a large capital purchase or long-term contractual commitment, and allows you to easily expand assets as needed.

Added Howe, “In hospitals particularly, RTLSs can play an important role in automation of common tasks—improving operational efficiency, increasing patient flow, and enhancing patient safety. Knowing the location, status, and movement of equipment and people can be used to improve hospital business processes and asset utilization, reduce capital expense and rental costs, and improve staff productivity.”

Scratch built RFID tags

Thursday, November 13th, 2008


[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.

Florida toll system chooses eGo sticker

Saturday, July 12th, 2008

Illinois_toll.jpgFlorida’s Turnpike Enterprise (FTE), which manages the statewide SunPass system, has selected TransCore’s eGo Plus RFID sticker for use on the state’s 460 miles of toll road. The paper-thin, batteryless tags will be sold as the SunPass “Mini” and be available this summer.

The eGo Plus sticker tag is a 915 MHz programmable, beam-powered, windshield-mounted tag packaged as a flexible sticker. Each eGo Plus sticker tag comes equipped with a factory-programmed unique tag identification number to prevent the tag from being duplicated. The eGo Plus technology is also being used by Houston’s Harris County Toll Road Authority, the Texas Department of Transportation, and the Washington Department of Transportation.

The FTE’s initial order with TransCore is for 1.5 million of the tags, which will join the more than three million hardcase SunPass tags currently in use on the state’s roads.

Art of RFID Antennas

Sunday, June 29th, 2008

Check this beautiful line arts of RFID antenna design technologies:

Outer Space

µ-Chip Hibiki by Hitachi.

This is an astronaut’s mobile phone kit, right? Nope! It’s Hitachi’s early gen 2 µ-Chip Hibiki, pronounced mu-chip, also known as the “5-yen tag,” introduced in late 2006. Why 5-yen? If ordered in large quantities, each one costs only ¥5. A bargain! Now, why this Greek letter? It’s a variation of the µ-Chip which is only tiny 0,4 mm square. However, the Hibiki is 102 x 135 mm in size.

Alpine Serpentine

Japanese DNP’s Nile.

We bet that the lab behind the shape of the Nile RFID chip by DNP must have had something like a radiant heater in mind as inspiration. These serpents have a minimalist elegance. Don’t get lost in its beautiful wavy lines, this is still an ultra-high-frequency chip with 96 bit memories.

Gesturing Man

The ‘global tag’ by UPM Raflatac.

A 512 bit memory is hidden in this shiny metal, simply called ‘global tag’ by UPM Raflatac. Check the tiny filigree pattern! How about an RFID necklace with ultra-high frequency (UHF)?

Alien Sktechbook

This must be part of an alien spaceship! The Rafsec Memory Stick by UPM Raflatac.

A memory stick? Oh, not your USB stick, this one has only 512 bit. Note that ultra-high frequency (UHF) RFID systems are being widely deployed since several large corporations got that through, including international retailers and — not to forget — the U.S. Department of Defense.

Picture Frame for Geeks

Rafsec 49 x81 mm Tag by UPM Raflatac’s.

OK, the shape of this Rafsec Tag isn’t that peculiar, but hey, its high frequency (HF) is in use worldwide. A typical high frequency would be 13,56 MHz. HF systems are widely used in libraries, mass transportation (think SUICA and PASMO train cards) and product authentication applications. Capacity: 1024 bits! Depending on the usage, this HF tag either comes as non-adhesive inlay, die-cut web with adhesive, filmic face (for wet inlay,) or in a tag with a paper face. Stylish.

Weather Satellite

A satellite! The Avery Dennison AD-612.

This multi-frequency inlay code-named AD-612 by Avery Dennison has the usual 860-960 MHz frequency — and an utterly space age shape! We wonder which sci-fi scientist came up with this sketch-like design that resembles an orbitting satellite.

Next Season’s Jewellery

Golden plate by Texas Instruments, the Tag-it HF-I Transponder.

Blinded by this glimmering gold, we get that this one isn’t exactly brand new, but still a nice sight; the high frequency Tag-it HF-I Plus Transponder Inlay by Texas Instruments goes by the standard 13,56 MHz and has a 2 Kb memory to store your precious data. This wafer is inked, ground and sewn onto tape. Nice sewing job!


ALN-9540 – “Squiggle™” by Alien Technology.

A true tag for the world, at least so says manufacturer Alien Technology. This little squiggle is operating between 860 to 960 MHz, with a ‘generation 2′ performance. It was created for most types of packaging, including products containing metal and water. Metal bento, anyone? Watch out, it’s a mere 97 x 11 mm!

The Labyrinth

The ALN-9529 – “Squiggle®-SQ,” another one by Alien Technology.

Oh, a little squiggle! This fancy-looking UHF operates between 860 and 960 MHz. Said to be ideal for item level tagging of plastic packaging such as pill bottles and apparel tags. So this is already in use at your local department store. Also featuring near-field and far-field communication. So talkative!

Ancient Cave-painting

A very stylised crab! UPM Raflatac’s Rafsec Crab.

If this were an ancient cave-painting you’d be amazed by its geometric shape. Well, it’s a stylised crab called Rafsec Crab and only slightly newer — also from the high-performing UHF, ultra-high frequency, group by UPM Raflatac. By the way, the other chips of the the same series have some quite weird shapes named Frog, DogBone or Hammer. Welcome to this unusual family! And what a modest memory of 96/240 bits.
