(If only things were so simple!) But they will send you a new card if you tell them your old one is getting worn out and needs a replacement. Of course, they won’t just send you out a little RFID chip and antenna to mount in your hacked up project. Given the time and effort put into creating this contactless payment ring, we think it’s pretty clear which camp he’s in.Īlright, so the whole ring making part sounds easy enough, but how does one get an RFID chip that’s linked to their account? Easy. Others think the ease and convenience of paying for goods by tapping their card or smartphone on the register more than makes up for the relatively remote risk of RFID sniffers. Some only see the technology as a potential security liability, and will go a far as to disable the RFID chip in their card so that it can’t be read by a would-be attacker. RFID payment systems are one of those things that the community seems to be divided on.

And, if society does collapse, we’ll all have a great source of diodes when the ATMs have all become useless. While it’s not going to be the most replicated hack, as it requires the destruction of a credit card to achieve, we love the ingenuity. Cutting templates and other details are available on Github. breaks down the details for anyone wishing to replicate the feat, going so far as to wind the coils in real time in his Youtube video. Turning the dial allows stations to be tuned in, and with a high impedance earbud hooked up, you’re listening to AM radio. Doing this allows for a much cleaner, thinner design, rather than using a variable capacitor which is comparatively hard to find. Other cards are cut up to create bobbins for winding coils to form a variable inductor, used to tune the radio. Of course, goes the whole hog, building the entire radio on a single credit card. It’s then a simple matter of hooking up the right pads on the credit card to the rest of a crystal radio circuit, and you’re all set. This is possible because the smart chip on many credit cards contains a diode. decided to build a crystal radio using a rather unconventional detector – the smart chip in a common credit card. Using a diode as a detector, the design generally uses less than 10 components and no battery, getting its power to run from the radio signal itself. Perhaps the simplest radio one can build is the crystal radio.
