Leeds based agency Propaganda have helped out homeless charity Simon on the Streets with a novel QR Code campaign. The QR Codes are printed on cardboard and then placed amongst blankets and belongings to look like a homeless person has been sleeping there. These installations are then situated around the city centre. The QR Codes resolve to a JustGiving page where the public can donate directly to the charity. Previous ideas to help the homeless with QR Codes have not really worked but I think this one does.
