Radio frequency identification (RFID) chips are everywhere today: in credit cards, driver’s licenses, and passports, and stuck to pallets of inventory for big retailers like Wal-Mart. Yet some RFID tags—especially the smallest and cheapest—still have no means to prevent them from yielding up their data to any passerby with an RFID reader. However, a soon-to-be-published report from a team of American computer scientists proposes a new RFID security measure that works by using the memory circuit. (source: spectrum.ieee.org)
