A QR code (Quick Response code) is a type of two-dimensional barcode that can store various types of data, such as text, URLs, emails, and even videos. It’s a matrix of black and white squares arranged in a specific pattern that allows smartphones to scan and decode the information stored within.

Importance and Use Cases

QR codes have become increasingly popular due to their ease of use and versatility. Here are some use cases:

• Marketing and Advertising: Businesses use QR codes to promote products, services, or events.
• Payment Systems: Some payment apps use QR codes for contactless transactions.
• Event Tickets: Event organizers distribute QR code tickets that can be scanned for entry.
