摘要: The system of the invention includes a method for monitoring changes in status or condition container using one more units (21) mounted to container. preferably include power supply (52), sensors (22) reflective energy with programmable parameters, globally-unique sensor identification, recording capability on timeline, long term memory and ability rebroadcast information RFID radio technology. Programmable hardware unit detects significant outputs as triggering event. (49) storing identification which can conventional devices that detect various forms including visible light, infrared magnetic fields, frequency sound. In embodiment, is inside shipping suitable distance transport. event be used tamper detection security.
