Episode 9 should be hitting the site within the next week…until then, enjoy the teaser!
In the second half of the RFID TTJ episode we covered how to clone or spoof an existing RFID tag. This was partially to expose the security flaws of RFID, but also because it can be very useful. I’ve stayed in a few apartments now that require an RFID tag to get in and out of the main gate. Sometimes you’ll end up getting only one or two RFID tags for the main gate when you have more people living in the same apartment. It’s also inconvenient if you have friends that come over often and you have to let them into the gate every time.
Almost all of this information and work was put together by Micah Elizabeth Scott over at scanlime.org. We simply experimented with the technology and found what works best for us.
I’ve been a college student for a few years now and one of the first things that I hacked together while staying in a dorm room was an RFID (Radio Frequency Identification) lock. I was always in a rush to get in and out of my room and having a wireless key made it that much easier. The challenging bit was that I needed to be able to attach it to my door without modifying any of the hardware and I also wanted it to be hidden from the outside. My first prototype was pretty rough, but over the past year I’ve refined my design and finished a minimalistic circuit board.
In this episode of TTJ we show you how to build your very own RFID door lock using our open source plans. We also take it to the next step and show you how RFID tags can be read and duplicated.
