[Eliot] and I hit [Major Malfunction]’s talk about RFID hacking. He’s put together a set of python scripts to read – and write RFID tags. He demo’d cloning a few tags – along with someone’s implanted RFID that’s used to lock and unlock a laptop. (It looked like the reader in the kit from ThinkGeek.) He’s kind enough to offer a selection of hardware on his site. (The usb RFID reader is pretty cheap.) His work has made plenty of headlines, including slashdot, but you can get the actual details, code and hardware on his site.
