Abstract
A system and method of asset sealing and tracking includes a first RFID device with a first identity that is permanently affixed to a container door, and removable second RFID device with a second identity is coupled to the first RFID device—and inserted through a locking hasp of the container door. The first RFID device inherits the second identity of the second RFID device thereby automatically associating the two devices. Thereafter the first RFID device broadcasts both identities. When the second RFID device is opened, so that the container door is allowed to open, the first RFID device can sense this and change its broadcast message to include that the second RFID device was opened.
