Disclosed is a method for a secure interchange of data between radio frequency identifier (RFID) tags/readers and the activity detection of tagged objects. Benefits include: • The ability for an RFID system to infer when objects it senses are moving • The ability for an RFID system to require increased effort on the part of physically distant readers, hence reducing the risk of unwanted reads by a physically distant, unknown, "attacking" RFID reader • The ability for RFID systems to flexibly report some, none, or all of the data they contain.
