In November, a Knorr food truck in chilly Stockholm offered free warm samples of the brand’s tomato and Thai soups. Visitors could eat it on the spot or take home the samples.
To ensure the visitors could also be retargeted through relevant mobile ads, Knorr equipped the truck and the people handing out the samples with battery powered iBeacons. Through these iBeacons, visitors to the truck who had the popular Swedish newspaper Aftonbladet app preinstalled were registered as having been there. Then instead of immediately pushing a coupon for Knorr soup to the user, they waited until the next time the user opened the Aftonbladet app to serve it up through a mobile ad on the start screen.
