CCTV surveillance is a fact of life nowadays for those living in large cities but the surveyors have been getting a surprise in Berlin. QR Code mosaic tiles applied with strong adhesive have been placed where they can be seen by the cameras and the pedestrians. The QR Codes when scanned read “please smile you’re being filmed”. Guerrilla campaigns like this one and a couple of others like QR Code spam and QR Code switch seem to originate in Germany, let’s see some worldwide competition here!
