Q&A: Should I Use a QR Code on My Direct Mail Marketing Piece?
Yes! Adding a Quick Response (QR) code to any printed piece makes it interactive for mobile phone users. A QR code is a two-dimensional graphical representation of information; after scanning the QR code, the information is displayed on the mobile phone screen.
Early uses of QR codes were to display a website or telephone number. Now they are used to display a coupon at checkout, send an email or text message, go to a personalized web page, or launch a video.
