In an effort to help empower first world citizens to make donations, the UN World Food Program commissioned the 'Food Link' campaign. Food Link allowed people waiting at a bus shelter to carry food to a hungry child with their smartphones. With just three steps, users could pick up virtual food from one bus shelter ad and bring it to the other.
Using RFID technology, the ads let your smartphone acquire pixelated food from a print ad. All you have to do is walk over to an opposing ad and drop the food off. After giving the child food, a video appears on your phone from the child in the ad. Your phone then gives you the option to donate and make the virtual food a reality.
