The New Zealand Herald uses a QR code to make it easier for readers to submit a letter to the editor for consideration. This is a smart use of a QR code. I mention it here because newsagents are yet to embrace QR codes in-store to drive shopper engagement -whereas big businesses in Australia and worldwide regularly use them to facilitate engagement.
A while back I launched a completely free QR code generation and content hosting platform – QRki – for any small independent retail (and other) business to use in the world. I funded the development of QRki and cover hosting costs as part of my commitment to support small and independent retailers.
