QR Codes, short for Quick Response Codes, are two-dimensional barcodes that contain information such as text, URLs, email addresses, or even GPS coordinates. They were first developed in 1994 by Masahiro Hara, an engineer at Toyota, to track parts during the manufacturing process. Today, QR codes have become a ubiquitous technology used in various industries and everyday life.

What are QR Codes?

QR codes consist of a square grid of black and white modules that can store up to 7,089 characters or more. The structure is divided into three main components:

• Finder Patterns: The four squares on each corner and the middle square on each side form a square dot pattern. These patterns help the scanner (camera) locate the QR code.
• Alignment Patterns: The two smaller squares inside each finder pattern serve as alignment markers to ensure accurate scanning.
• Data Module: The remaining space in the grid contains the actual data being encoded.

Importance and Use Cases

QR codes have gained popularity due to their unique advantages:

• Convenience: QR codes allow users to quickly access information, such as a website URL, with just one tap on their smartphone camera.
• Space efficiency: QR codes can store more data than traditional barcodes in less space.
• Versatility: QR codes can be used for various purposes, including:
  • Marketing and advertising (promotional offers, coupons, product information)
  • Event management (tickets, schedules, maps)
  • Education (interactive learning materials, quizzes)
  • Logistics and supply chain management (tracking inventory, shipping information)
