RFID hacking has been around for years, but so far all the builds to sniff data out of someone’s wallet have been too large, too small a range, or were much too complicated for a random Joe to build in his workshop. [Adam]’s RFID sniffer gets around all those problems, and provides yet another reason to destroy all the RFID chips in your credit cards.
The project was inspired by this build that took a much larger RFID reader and turned it into a sniffer capable of covertly reading debit cards and passports from the safety of a backpack or briefcase. [Aaron]’s build uses a smaller off-the-shelf RFID reader, but he’s still able to read RFID cards from about a foot away.
[Aaron]’s build is very simple consisting of only an Arduino and SD card reader. [Aaron] is able to capture all the data from an RFID card, write that data to the SD card, and emulate a card using his RFID cloner.
What’s really impressive about the build is that [Aaron] says he’s not a programmer or electrical engineer. His build log is full of self-denegration that shows both how humble [Aaron] is and how easy it is for anyone with the requisite skill set to clone the bank card sitting in your wallet. We don’t know about you, but you might want to line your wallet with aluminum foil from now on.
