QR (Quick Response) codes are two-dimensional barcodes that contain information such as URLs, contact details, or text messages. They have become increasingly popular in recent years due to their ability to quickly share content and connect people with the physical world.

Definition of QR Codes

A QR code consists of a square grid of black and white squares, arranged in a specific pattern that can be read by a device equipped with a camera and a QR code scanner. The information contained within a QR code is decoded using algorithms that convert the patterns of black and white squares into machine-readable data.

Importance and Use Cases

QR codes have numerous applications across various industries:

1. Marketing: QR codes are used in advertising campaigns to link customers directly to websites, online surveys, or promotions.
2. Commerce: QR codes enable contactless payments, making transactions faster and more secure.
3. Information Sharing: QR codes facilitate the sharing of information, such as product details, instructions, or news articles.
4. Event Management: QR codes are used for ticketing, registration, and communication with attendees.
