Heathrow's Terminal 5 is the first UK airport building to be designed around the technology that runs it.

BAA and British Airways worked together on T5. The baggage system was designed by BAA, Vanderlande and IBM. A 2D barcode is attached to each bag with information on where it needs to go, and handlers use hand-held scanners to update the bag's position on the system and to work out which route it should take.
