Laptops no longer ‘expensive paperweights’.

The product is larger than a conventional 3G card, but doubles as a network
card and a laptop “ignition key”. The laptop’s drives are encrypted, and the
card contains all encryption keys and network passwords so the laptop cannot be
used unless it is inserted. It contains an embedded Linux system, and a GPS
receiver, as well as its own five-day batteries, so it can be used to remotely
locate and disable any laptop that goes missing.
