QR codes were first introduced in Japan in the 1990s for use in manufacturing and inventory management. However, it wasn’t until the rise of smartphones that they gained popularity as a marketing tool, particularly in Asia. Today, QR codes are used worldwide in various contexts, including:

• Marketing campaigns to drive traffic to websites or landing pages
• Providing information about products or services
• Sharing contact details or social media handles
• Accessing exclusive content or promotions
