Here are some possible answers to questions about the luggage scanner.

A) The passenger has to put his belongings on the conveyor belt and collect them afterwards. The operator has to look at the scan of the luggage, pointing out anything suspicious so someone can inspect it more carefully.

B) Without this material artefact, every item of luggage would need to be searched by hand. That would mean more people working longer hours, passengers queuing much longer at security, and could even mean the airport would have to be bigger to accommodate the queues.

C) The scanner delegates the work of searching the bags to a machine. As well as saving staff time, the scanner can record and identify the contents of bags and separate different materials-- organic, non-organic, non-penetrable – using colour codes.

D) Scripting during the security check is relatively limited and overt. It configures the passenger in ways that make the process run efficiently, giving instructions on conduct like removing laptops and shoes, putting phones and change into trays, and so on.
