More and more today, it is becoming harder to avoid having some sort of RFID tag in your wallet. [bunnie], of bunnie:studios decided to ease the clutter (and wireless interference) in his wallet by transplanting the RFID chip from one of his subway cards into his mobile phone. Rather than the tedious and possibly impossible task of yanking out the whole antenna, he instead pulled the antenna of a much more accessible wristband with an RFID chip of similar frequency instead. Nothing too technical in this hack, just a great idea and some steady handiwork. We recommend you try this out on a card you haven’t filled yet, just in case.
[Matt] has mixed up a batch of two RFID reading door lock systems. While the “door lock” part of the setup has yet to come into existence, the “RFID reading” section is up and running. By using the Parallax RFID readers (for cheap, remember?) and an Arduino, [Matt] is able to parse an RFID tag, look its number up in a database, and then have a computer announce “Access Denied” in a creamy “Douglas Adam’s sliding door of Hitchiker’s Guide” kind of way with Python.
Good books aside, catch a not as exciting as you’re thinking video after the jump.

[Carl] has done a lot of work developing a collection of RFID hardware. The two cards you see above are spoofers that can be programmed in the field using the keypad on the left, or the rather intimidating banks of DIP switches on the right. We also enjoyed his look at the Atmel T5557 and ATA5567 on-card chips used for the tags themselves. He shared the schematics for his designs but unfortunately he’s not distributing the firmware. None-the-less, if you’re interested in learning more about RFID this is a wonderful resource as it covers readers, writers, spoofer, and tags.
[Jair2K4] likes his RFID almost as much as he likes his chaw. Ever since his car was stolen he’s had to start it using a screwdriver. Obviously this is not a good way to leave things so he decided to convert his starter to read an RFID tag. He installed an RFID transponder he picked up on eBay, wiring it to the ignition switch. He’s removed the clutch-check sensor and wired a rocker switch to enable the RFID reader. We presume the rocker switch will eventually be used to shut the car off as well.
While most would have purchased a key-chain RFID tag, [Jair2k4] went far beyond that and had the tag implanted in his hand. This is an honor usually reserved for pets and until he adds RFID functionality to the door locks maybe a key fob would have been a better answer. But, to each his own. See his short demonstration video after the break.

Have you been working on a MIDI controller that uses RFID to identify and control different instruments? No? Neither have we but now we’re going to have to look into it. That’s because [Martin.K] has done a lot of the work for us. His nfOSC package links an RFID reader to the Open Sound Control library.
In the video after the break we see [Martin] placing RFID tags onto a Touchatag reader. With each addition, his software triggers a tag add event that OSC picks up and translates to a midi event; in this case it adds a new instrument to the mix. Can this be used to relieve musicians from staring at computer screens during performances? What if there was a small shelf in front of you? As you happily play your electric Didgeridoo, small items with RFID tags on them can be added or removed from that shelf to change the samples that are triggered when toiling away on that sonic weapon. This should be fun!

During our daily rounds we stumbled upon Duino Tag. Sure it’s not as awesome as a coil gun but it really sparked our imagination. First the base: an Arduino is wired up with IR LEDs and placed inside of a plastic pistol. A second Arduino with an IR receiver is scanning for the first Arduinos signal. A ‘shot’ of IR light is ‘fired’ and detected, you get a ‘kill’.
The base is nothing amazing, but it really gives us some ideas and we would like to see it expanded upon. [J44] has already put in a piezo and other LEDs to simulate muzzle flash and other effects. But we like to go further. Start off with multiple pistols and players. Include GPS to track players current position, and wireless to update each player of another player. A small wrist watch display could act much like a UAV. Add some expansions like IR ‘grenades’ and you’ve got a full-out war! What would you like to see?
RFID seems to have invaded every part of our lives. Sure, the technology has been primarily used in government and industry, but that doesn’t mean that it doesn’t have consumer applications. Recently, we posted about [max’s] RFID dorm room lock, that he built to provide a safe, convenient way to access his room. A while back, we talked about an RFID spatially aware address book that used a combination of rfid tags and post-it notes to control the NFC enabled Nokia 3220 cell phone. Both of these projects highlight unique applications where RFID is used. We bash on RFID from time to time, mostly due to its security (or lack there of). That said, there is an interesting consumer solution out there for people who want to voluntarily use RFID called Touchatag (formerly known as Tikitag). The cool thing about Touchatag is that it uses a combination of RFID and QR (2-D barcode) tags to trigger applications on the Touchatag website. The starter kit, which includes 10 tags and a USB RFID reader, goes for about $40; a decent price considering the hacking potential for the RFID reader. In addition to using the reader, you can also use any NFC enabled phone to read the tags. While NFC enabled phones are currently few and far between, the technology will likely be implemented in many of the new phones released in the coming year.
We’re curious, what do you think is next for consumer RFID? What kind of innovative project ideas do you have?
