QR codes can be placed almost anywhere—on posters, brochures, pamphlets, newspapers, magazines, business cards, billboards, and product packaging. However, it is best to avoid adding them to shining, wrinkly, reflective surfaces and moving objects, as the QR codes will most likely be undetectable or unscannable. Once you have decided where to place your QR code, you can start using your code more effectively, which will positively affect the amount of scans you receive. The best placement for QR codes includes common customer touchpoints, in-store displays, printed media, physical products, etc.
