Transit Tales is an audio storytelling experience built on live train data and powered by AI. QR codes across Sydney's 215 stations launch the free mobile web app. Commuters select their destination and the platform calculates the exact journey time, then delivers a classic novel reimagined into an entirely new genre, its pacing and narrative arc shaped by the route, ending precisely as they arrive. For Mastercard, the activation transforms the transit network itself into a brand canvas, turning the moments between taps into something genuinely Priceless.
