People get bored at airports, I suppose. But this is still an unlikely use of barcode + mobile, I think.
Gatwick Airport is using 1D barcodes to give links to information about the airport – specifically about upgrades it is carrying out.
A Release says:
“Gatwick Airport has unveiled a novel way of bringing its £1 billion investment programme to life, through a barcode ‘Gatwick Discovery Tour.’ Becoming the only airport in the world to use standard barcodes as an audio-visual information tool, Gatwick is also the first UK brand to work with stickybits (www.stickybits.com), whose free mobile application is used to scan the codes.
Gatwick is kicking the tour off at the North Terminal inter-terminal shuttle departure point. A video shows how the new shuttle route between the North and South Terminals was built
Over the coming weeks and months, more barcodes will be introduced at check-in and just after security in the North Terminal as well as the forecourt areas and immigration in the South Terminal.”
