You see a QR Code on a sign and you scan it. Simple enough, the code resolves to a message urging you to make a phone call. Inquiring young people made the call. What happened next was not only entertaining, it was a brilliant marketing campaign.
Several bold young people scanned the QR Code, made the call, entertained the crowd and were well rewarded for following the directions received.
Chilean fashion company, Americanino created a “Flash event” with their QR Code and this message ” “Cuando vives el estado hipnótico de Americanino, los cambios no se hacen esperar. Atrévete a llamar a este número +56 9 67349967, compruébalo y no te muevas de acá”. This translates as: “When you live Americanino hypnotic state, the changes will not wait. Dare to call this number +56 9 67349967, check it and do not move from here. “ (Google Translate)
