What are QR Codes?

A QR code (Quick Response Code) is a type of two-dimensional barcode that can store data such as text, URLs, emails, phone numbers, and more. They were originally designed for use in manufacturing and inventory management but have since become widely used across various industries and applications.

QR codes consist of three main parts:

1. Finder patterns: The four squares at the corners of a QR code are called finder patterns. These help the scanner find the code and align it correctly.
2. Alignment pattern: The smaller square in the middle is called an alignment pattern, which helps the scanner determine the orientation of the code.
3. Data module: This is the area containing the actual data being stored within the QR code.

Importance of QR Codes

QR codes have become an essential part of modern life due to their numerous benefits:

1. Contactless transactions: QR codes enable seamless payments, reducing the need for physical cash or cards.
2. Inventory management: Manufacturers use QR codes to track inventory levels and manage supply chains efficiently.
3. Marketing and advertising: Businesses utilize QR codes to reach a wider audience, share content, and promote products.
