QR codes have evolved from a simple utility into one of the most powerful tools in modern marketing. What was once used primarily for inventory tracking is now a dynamic bridge between the physical and digital worlds—connecting print, packaging, events, and real-world experiences directly to online engagement, data, and conversions.
