In Melbourne, more than 25,000 kids are homeless. In order to help them find their way back home, the Public Transport of Victoria is using technology and a unique ticket purchasing system for commuters. Interactive posters were created that enable commuters to donate public transport cards for homeless kids directly through the billboard. By touching the billboard with their transport cards, the value of the ticket is transferred as a donation to the homeless youth charity, Ladder. Each time a donation is made, the young homeless person seen on the poster leaves for home.
