QR codes are two-dimensional barcodes that can be scanned by mobile phones to provide information like text or a URL. They allow physical retail experiences to be connected with digital experiences. Retailers should use QR codes because many consumers now use mobile phones during shopping and own smartphones. QR codes can enrich the customer experience by educating them about products and enabling social media interactions, store information, and offers to engage customers. Successful use of QR codes requires setting goals, clear instructions, incentives, and follow-up mechanisms. Several retailers like Best Buy are using QR codes well while others are missing opportunities.
