QR Codes in Airports: Wayfinding, Gate Changes, and Duty-Free Offers

1. Wayfinding at Scale

Airports are large and change layouts frequently. A QR on each major corridor sign links to a live interactive map showing the current terminal layout, gate assignments, and walking times.

2. Gate Change Alerts

A QR on the boarding pass links to a real-time flight status page. Passengers in the lounge or shops can scan once and bookmark the page to receive gate change updates without refreshing the departure board.

3. Duty-Free Offers

A QR at duty-free store entrances links to the day's featured deals and product availability. Pre-purchase and collect on arrival at the destination is also an option.

4. Accessibility Information

A QR at accessibility desks and information points links to a guide for passengers with reduced mobility: assistance request forms, accessible routes, and priority boarding procedures.

5. Link Stability

Airports have multiple terminals and the layout changes with construction. Use a URL structure that supports terminal and version parameters so links remain valid through building work.
