Your mobile phone, now with 100% more RFID

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.

    0 RFID + 100% more RFID = 0 RFID, FYI

    adhesive tape + two devices = hack?

    I will be going to YK in the spring, and I think they use RFID tags in the student ID, any suggestions on “low profile” rfid readers/spoofers and a rfid tag?

    @Bob

    The posted image might give people the wrong impression on this one. If you look at the write-up, bunnie shows how to remove the RFID chip from the card and attach it to a larger antenna from a different RFID tag.

    It isn’t the most complicated hack on the site, but the images and description of grafting a new antenna on an RFID chip is pretty interesting.

    Opinion retracted.

    Be carefull doing this hack, depending on the transit operator, you might get in trouble with the rent-a-cops if they ask to see your ticket/pass.

      Usually you can claim to have “lost” your transit card, and get another for free/minimal cost. Just use the spare in case of that, and implant the RFID from the other into your hand/phone :)

  8. Bob says:

    Are you saying that if I do this with the rfid tag in my passport, the customs agent won’t accept my phone as id?

  9. James says:

    Is it really so much harder to get a card out than it is to get a phone out? Or are we all glued to our phones these days, so it gets in the way of extracting a card from a pocket?

    Younger people might not give a damn but older people +1 efficiency.

    I kind of did the same thing with much less work. I did have a huge case to work with on my Bold 9000

    have a look and tell me what you think. As well any experienced antenna users here that could tell me why phone manufacturers have not implemented this in phones yet?

    @Bob:
    DUCT TAPE + two devices = hack.

    Also, any geek could rip off RFID. My favorite hack is to take a hole punch to my credit cards’ RFID chips.

    FUCK THE CHIP!
