Stocking shops at airports based on arrivals

With increasing restrictions and costs on what you can take with you on aircraft, and the ever-present threat of forgetting to buy some thing in the first place, being able to pickup souvenirs and gifts in arrivals as you return home is a good idea.

The challenge for the shops in arrivals is to carry enough stock to tailor to every destination that's being arrived from, and also to put that stock on display. One solution to this might be to have the display of arrivals' shops on a conveyor belt. The conveyor belt would be connected to a computer with access to the arrivals data, allowing relevant gifts and souvenirs to be brought into view to meet each arrival.
