QR codes can make mobile marketing faster and more direct. They give users a simple way to reach websites, product info, or discount offers just by scanning. For example, a small business can print a QR code on flyers or posters that links straight to a shop page. To make QR codes more useful, they should lead to pages that open quickly and look good on phones. Clear instructions like "Scan to learn more" help people know what to expect. The design of the QR code can also match the brand's colors so it feels more trusted and familiar. How else do you think QR codes can help reach more customers?
