Can a QR code be added?
A QR code can be added to a reverse graffiti, chalk or rain advertisement. The QR code can be placed next to the advertisement by means of a floor sticker that is specifically suitable for outdoor use. Usually a size of approximately 10x10cm is used for this so that the QR code is not too dominant, but it does stand out enough. Of course, the QR code can refer to a specific URL so that the interaction can be measured directly.
