First of i want to say, the government isnt RFID tagging everyone to keep track of people, that is a ridiculus claim. RFID chips cant hold very much data and need to be fairly close to be scanned. (However your phone is a better target for stuff like that…)

Anyway, there might be reasons to want to check if things are marked with an RFID tag. Maybe on clothes you bought that set of alarms in stores, or check if a buscard is broken.. Either way here is an open source RFID sniffer, to check if there are any RFID chips nearby! (more…)
