Patent attributes
A container security device includes a housing, electronic circuitry, and cabling. The electronic circuitry is disposed within the housing, and includes first and second microprocessor functions and an interface for accepting and providing data. The cabling is removably coupled to the housing, provides the only communicative coupling between the first microprocessor function and the second microprocessor function, and is adapted to be attached to a container latch so as to break the communicative coupling if the latch is opened. The housing includes a port for the electronic circuitry interface. A method of providing container security includes closing a container using a latch device and removably coupling the cabling to the housing so that the communicative coupling is broken if the latch is opened, providing the only communicative coupling between the first microprocessor function and the second microprocessor function.
