RFID Security
I put some research into a post some time ago; recently decided to archive the work for future reference. Regarding
RFID:
RFID stands for Radio Frequency Identification, and is essentially a Tesla-esque hack to allow contactless, bidirectional storage of small amounts of data on trivial circuits powered by the reader infrastructure itself. It’s most commonly deployed nowadays as a replacement for magnetic-swipe oriented systems, as the lack of an exposed data surface and the absence of contact during scanning make RFID astonishingly reliable. The functionality is quite compelling, as Gilette’s mass purchase shows — what if you never needed to do inventory? What if you could just have a few sensors throughout your warehouse do a “mass ping” and acquire from the mass of replies precisely what needs to be restocked?
What if indeed. The rest is available here.
