Concept: QR Codes and Mobile Scanning

QR codes (Quick Response codes) are two-dimensional barcodes that contain information such as URLs, text messages, and contact details. They were originally designed for use on small areas like business cards or product labels but have since become ubiquitous in many industries.

QR codes can be generated using various tools, including online generators and software development kits (SDKs). They have become an essential tool for businesses, marketers, and individuals to share information quickly and efficiently.
