Putting small QR codes 8’ in the air makes it a challenge to participate in your promotion. I literally had to hold my camera at maximum reach overhead to scan this one. There was signage with functional QR Code at the store entrance. But everything else storewide was well-nigh impossible to access. CLICK the thumbnail for a lead-in to the promotion. Please, place your QR where accessible, not overhead.
